Study design and exam specifications

Compiled 15 September 2026, for a study site aimed at students targeting a study score of 45+. Every substantive claim is tagged with its source. Where a source is silent, garbled, or ambiguous, that is stated explicitly rather than filled in.

0. Sources, and how to read the evidence tags

A note on the title of this document. "2023–2027" is the accreditation period as printed on the 2022 release of version 1.1 ("Units 1–4: 1 January 2023 – 31 December 2027"). The October 2025 file currently on the VCAA website has had the end date removed: its header reads "VCE Mathematics Study Design 2023" and its Important Information section says only "Units 1–4: 1 January 2023." Accreditation periods are routinely extended, so "2023–2027" should be read as "the current design, first examined in 2023" rather than as a guaranteed end date.

0.1 A note on questions.json and why it can be trusted

questions.json is a reconstruction from VCAA's published examination reports. It can be validated, because for 2006–2011 VCAA also published paper-level means, and the reconstruction reproduces them:

Agreement is within rounding error on every multiple-choice section and within 0.6 marks on every Exam 1. The small residual on Exam 1 is expected: VCAA rounds each mark-distribution row to whole percentages, so the reconstructed mean inherits up to a few tenths of a mark of rounding bias. The reconstruction is therefore reliable to roughly ±0.5 marks at paper level and exact at question level, because the question-level percentages are simply VCAA's own published numbers.

0.2 Known corpus defects

These matter if you are drilling from the archive:

• Four paper text files are empty (24–36 bytes, header only): Documents_exams_mathematics_2024_2024specmaths1-w.txt, ...2024specmaths2-w.txt, 2025-05_2025-NHT-specialistmaths1.txt, 2025-05_2025-NHT-specialistmaths2.txt. The 2024 November papers must be worked from the PDFs in corpus/sm/raw/ or from the 2024 reports.
• The 2011 papers (Documents_exams_mathematics_2011specmath1-w.txt, ...2011specmath2-w.txt) extracted with a CID-shifted font encoding: every code point is offset and all spaces are lost. They are unreadable to plain text search; the underlying PDFs are fine.
• No NHT sittings exist before 2017. VCAA's Northern Hemisphere Timetable began for Specialist Mathematics in 2017. 2020 NHT is missing from the corpus, and the 2026 November papers do not exist yet.
• papers.json mislabels every Specialist Mathematics entry as "subject": "Further Mathematics". This is a metadata bug in the index, not in the content.
• Documents_exams_mathematics_specmath1-samp-w.txt opens with a stray header line VET EQUINE STUDIES (SAMPLE) — an artefact of VCAA's own publishing template, not a content error.

1. The six areas of study

1.1 The structure, and an important caveat about "key knowledge and key skills"

[SD] opens the Units 3 and 4 section:

"Specialist Mathematics Units 3 and 4 consist of the areas of study: 'Algebra, number and structure', 'Calculus', 'Data analysis, probability and statistics', 'Discrete mathematics', 'Functions, relations and graphs', and 'Space and measurement'. The development of course content should highlight mathematical structure, reasoning and proof and applications across a range of modelling contexts with an appropriate selection of content for each of Unit 3 and Unit 4. The selection of content for Unit 3 and Unit 4 should be constructed so that there is a balanced and progressive development of knowledge and skills with connections among the areas of study being developed as appropriate across Unit 3 and Unit 4."

A structural point that is widely misunderstood and matters for how you read the study design. In VCE Specialist Mathematics Units 3 and 4, the study design does not attach key knowledge and key skills to each area of study. It attaches:

• content dot points to each area of study (introduced by the phrase "This area of study includes:" or "This topic includes:"), and
• key knowledge and key skills to each of the three outcomes, each of which explicitly "draw[s] on key knowledge and key skills outlined in all the areas of study".

So there is no "key knowledge for Calculus". There is content for Calculus, and there is key knowledge for Outcome 1 which spans everything. §1.2–§1.7 below give the area-of-study content verbatim; §2 gives the outcome key knowledge and key skills verbatim. Both are examinable — [SPEC] is unambiguous:

"All of the content from the areas of study and the key knowledge and key skills that underpin the outcomes in Units 3 and 4 are examinable."

1.2 The Unit 3 / Unit 4 split — and why it is advisory, not prescriptive

[SD] states:

"For Unit 3 a selection of content would typically include content from the 'Discrete mathematics', 'Functions, relations and graphs', 'Algebra, number and structure', 'Space and measurement' and 'Calculus' areas of study. In Unit 4 the corresponding selection of content would typically consist of the remaining content from the 'Discrete mathematics', 'Calculus', and 'Space and measurement' areas of study and the content from the 'Data analysis, probability and statistics' area of study." (emphasis added)

The word is "typically". Unlike General Mathematics — where the study design hard-assigns Data analysis and Recursion to Unit 3 and Matrices and Networks to Unit 4 — Specialist Mathematics leaves the split to the school. Three consequences for a 45+ candidate:

1. Neither examination is partitioned by unit. [SPEC] says of both papers that they "will cover all areas of study". There is no Unit 3 section and no Unit 4 section.
2. The only content that is genuinely Unit-4-only in practice is the statistics (Area of Study 6), because it is the one area the study design assigns wholly to Unit 4 and the one that cannot start until Mathematical Methods Units 3 and 4 have delivered the normal distribution.
3. Discrete mathematics (proof), Calculus and Space and measurement are explicitly split across both units. The study design says Unit 4 contains "the remaining content from the 'Discrete mathematics', 'Calculus', and 'Space and measurement' areas of study" — i.e. all three straddle the boundary.

The table below is therefore the typical allocation implied by [SD], not a rule. Individual schools legitimately differ.

1.3 Assumed knowledge

[SD]:

"Specialist Mathematics Units 3 and 4 assumes familiarity with the key knowledge and key skills from Mathematical Methods Units 1 and 2; the key knowledge and key skills from Specialist Mathematics Units 1 and 2; and concurrent study or previous completion of Mathematical Methods Units 3 and 4. Together these cover the assumed knowledge and skills for Specialist Mathematics Units 3 and 4, which are drawn on as applicable in the development of content from the areas of study and key knowledge and key skills for the outcomes."

"In undertaking these units, students are expected to be able to apply techniques, routines and processes involving rational, real and complex arithmetic, sets, lists, tables and vectors, diagrams and geometric constructions, algorithms, algebraic manipulation, equations, graphs, differentiation, anti-differentiation and integration and inference, with and without the use of technology. They should have facility with relevant mental and by-hand approaches to estimation and computation. The use of numerical, graphical, geometric, symbolic and statistical functionality of technology for teaching and learning mathematics, for working mathematically, and in related assessment, is to be incorporated throughout each unit as applicable."

And in the front matter, [SD] adds the enrolment rule:

"Enrolment in Specialist Mathematics Units 3 and 4 assumes a current enrolment in, or previous completion of, Mathematical Methods Units 3 and 4."

This is load-bearing on the exams. Because Mathematical Methods Units 3 and 4 is assumed, everything in Methods is fair game in a Specialist paper without warning: the normal distribution, binomial distribution, integration of exponentials and logs, the product/quotient/chain rules, Newton's method, discrete and continuous random variables, and confidence intervals for a proportion (which Specialist then extends to the mean). Specialist Units 1 and 2 are likewise assumed, which is where matrices, combinatorics, graph theory, sequences and series, and the geometry used in vector proofs live — the study design names all of these explicitly as legitimate contexts for proof in Area of Study 1 (see §1.4).

1.4 Area of Study 1 — Discrete mathematics (Logic and proof)

This area of study is entirely new in the 2023–2027 design. It has no counterpart in the 2016–2022 or 2006–2015 designs (see §5).

[SD] overview, verbatim:

"In this area of study students cover the development of mathematical argument and proof. This includes conjectures, connectives, quantifiers, examples and counter-examples, and proof techniques including mathematical induction. Proofs will involve concepts from topics such as: divisibility, inequalities, graph theory, combinatorics, sequences and series including partial sums and partial products and related notations, complex numbers, matrices, vectors and calculus. The concepts, skills and processes from this area of study are to be applied in the other areas of study." (emphasis added)

[SD] content, verbatim:

This area of study includes:
- conjecture – making a statement to be proved or disproved
- implications, equivalences and if and only if statements (necessary and sufficient conditions)
- natural deduction and proof techniques: direct proofs using a sequence of direct implications, proof by cases, proof by contradiction, and proof by contrapositive
- quantifiers 'for all' and 'there exists', examples and counter-examples
- proof by mathematical induction.

Reading this carefully. Three features are easy to miss and all three have been examined:

1. The contexts list is not decorative. "divisibility, inequalities, graph theory, combinatorics, sequences and series including partial sums and partial products and related notations, complex numbers, matrices, vectors and calculus" is a licence to set an induction proof about anything. VCAA's own [SAMPLE] Exam 1 set induction on a series sum (Q1: prove 1/2 + 1/4 + 1/8 + ... + 1/2ⁿ = 1 − 1/2ⁿ), on an inequality (Q2: prove 2ⁿ > n² for n ≥ 5, including the sub-question "Show that n₀ = 5"), and on divisibility (Q3: prove 9ⁿ − 5ⁿ is divisible by 4). The live papers have used the same range — 2026 NHT Exam 1 Question 2 (3 marks) reads "Prove by mathematical induction that the number given by n² + 5n is even for all n ∈ N".
2. "The concepts, skills and processes from this area of study are to be applied in the other areas of study." Proof is not a topic that sits in one question; it is a mode that can be attached to any other area. This is the sentence that makes a "show that" or "prove that" instruction legitimate inside a vectors question or a complex numbers question.
3. The word "counter-examples" is in the content. It is examined as a multiple-choice item type. 2025 Exam 2 Question 2 (Section A) reads: "Consider the following statement. 'If f''(0) = 0, then the graph of f necessarily has a point of inflection at x = 0.' A counter-example that disproves this statement is when …" with options including f(x) = x⁴ + x. [RPT25 E2] records 48% choosing the correct option D against 40% choosing C.

Evidence that this area is examined in both papers. [RPT23 E1] states outright: "New topics tested in 2023 included integration by parts (Question 5), area of a surface of revolution (Question 7), proof by induction (Question 8) and planes (Question 9)." [RPT24 E1] repeats: "New topics from 2023 were again tested in 2024. In particular, proofs (Question 2), the cross product (Question 4b and Question 10) and lines in space (Question 10)." On the technology-active paper, 2025 Exam 2 Question 1 (Section A) tested the contrapositive — 93% of the state answered it correctly ([RPT25 E2]), and 2024 Exam 2 Question 1 tested the contrapositive too, at 72% ([RPT24 E2]).

What is not here — and this matters, because the area of study is called "Discrete mathematics". There is no number theory as content. The words "Euclidean", "modular", "prime" and "greatest common divisor" appear nowhere in the Specialist Mathematics Units 3 and 4 section of [SD]. The preamble's list — "divisibility, inequalities, graph theory, combinatorics, sequences and series … matrices, vectors and calculus" — names these only as sources of things to prove, not as topics to be learned here. Prime factorisation, modular arithmetic and the Euclidean algorithm sit in Specialist Units 1 and 2, which are assumed knowledge, so a divisibility proof may legitimately lean on them; but they are not a Units 3 and 4 content dot point and cannot be examined for their own sake. The corpus corroborates: a search for Euclidean algorithm|gcd|highest common factor across all 97 corpus files returns zero hits, and modulo|congruen|divisible returns a single incidental hit [PAPERS].

There is also no formal truth-table logic, no set-theoretic proof apparatus, and no strong induction named explicitly — though "proof by mathematical induction" is not qualified, so a strong-induction step is not excluded by the wording.

1.5 Area of Study 2 — Functions, relations and graphs

[SD] overview, verbatim:

"In this area of study students cover rational functions and other simple quotient functions, curve sketching of these functions and relations, and the analysis of key features of their graphs including intercepts, asymptotic behaviour and the nature and location of stationary points and points of inflection and symmetry."

[SD] content, verbatim:

This area of study includes:
- rational functions and the expression of rational functions of low degree as sums of partial fractions
- graphs of rational functions of low degree, their asymptotic behaviour, and the nature and location of stationary points and points of inflection
- graphs of simple quotient functions, their asymptotic behaviour, and the nature and location of stationary points and points of inflection.

This is the smallest area of study in the whole design — three dot points — and the most consistently examined. It carries roughly 16% of the tagged marks in the 2023–2025 November papers ([QJSON]), and it is the single most reliable generator of an Exam 1 Question 1.

What "rational functions of low degree" means in practice. The study design never defines "low degree". The archive does: the papers stay at numerator and denominator degree ≤ 3, and overwhelmingly at (quadratic)/(linear) or (linear)/(quadratic). 2025 Exam 2 Question 3 (Section A) is typical: "The graph of y = (x² + a)/(bx + c) has an asymptote given by y = ½x − ¼ and a y-intercept of −2. The values of a, b and c are …" — this is exactly (quadratic)/(linear) with an oblique asymptote, answered correctly by 68% of the state ([RPT25 E2]).

"Simple quotient functions" is the deliberately loose term. It covers f(x)/g(x) where f and g need not be polynomials — e.g. 1/(x² − 4), x/√(x² + 1), e^x/(x − 1), 1/sin(x). Sketching these by hand, with correct asymptotic behaviour and correctly justified points of inflection, is a standing Exam 1 demand. [RPT23 E1] lists "sketching rational functions (Question 1b.)" among areas of strength.

Where the state loses marks. [RPT25 E2] is blunt about graph questions: "Many graphs were not accurately drawn… Care must be taken with the shape of the graph, with asymptotic behaviour and smooth curves. Several responses, incorrectly, sketched the point of inflection as a stationary one. Many responses did not label the horizontal asymptote y = 0." In [QJSON], 'Functions, relations and graphs' has the lowest median full-mark rate of any content-bearing area in 2023–2025 at 44% (n = 22 written parts) — lower than Calculus (54%), Space and measurement (55%), Algebra (61%) and Statistics (65%).

1.6 Area of Study 3 — Algebra, number and structure (Complex numbers)

[SD] overview, verbatim:

"In this area of study students cover the algebra of complex numbers, including polar form, factorisation of polynomial functions over the complex field and an informal treatment of the fundamental theorem of algebra."

[SD] content, verbatim (equations linearised from the source OMML):

This area of study includes:
- De Moivre's theorem, proof for integral powers, powers and roots of complex numbers in polar form, and their geometric representation and interpretation
- the nth roots of unity and other complex numbers and their location in the complex plane
- factors over C, of polynomials; and introduction to the fundamental theorem of algebra, including its application to factorisation of polynomial functions of a single variable over C, for example, z⁸ + 1, z² − i or z³ − (2 − i)z² + z − 2 + i
- solution over C of polynomial equations by completing the square, use of the quadratic factorisation and the conjugate root theorem.

Four things to notice.

1. "De Moivre's theorem, proof for integral powers" — the proof is named. This is a direct hook into Area of Study 1: an induction proof of De Moivre for positive integer n is squarely examinable, and the 2023 design is the first to say so.
2. The worked examples in the dot point are informative. z⁸ + 1 is a roots-of-unity-style factorisation over C. z² − i requires a square root of a non-real number. z³ − (2 − i)z² + z − 2 + i has non-real coefficients, which means the conjugate root theorem does not apply to it — VCAA chose that example deliberately to signal that students must know the theorem's hypothesis, not just its conclusion.
3. The conjugate root theorem is explicitly named, and is a standing Exam 2 Section A item. 2025 Exam 2 Question 5: "The equation z³ + az² + bz + 52 = 0, where a, b ∈ R and z ∈ C, has a solution z = 2 − 3i. The value of ab is …" — the a, b ∈ R condition is the whole question.
4. Regions and relations in the Argand diagram survive. They are not in the Units 3 and 4 content dot points above, but they are in the Outcome 1 key skills: "represent regions of an Argand diagram using complex relations" (§2.1). VCAA's own [SAMPLE] Exam 2 Section B Question 1 does exactly this: sketch {z : z·z̄ = 4} and {z : Arg(z) = π/4}, then shade {z : z·z̄ ≤ 4} ∩ {z : Re(z) + Im(z) ≥ 2} and find the area of the shaded region. And the live papers have followed: 2025 Exam 2 Question 2 (10 marks) opens "Sketch {z : z·z̄ = 4}, z ∈ C on the Argand plane below", then asks for {z : |z − 2i| = |z − 3 − i|} on the same axes, then for the points of intersection "expressing your answers in the form a + ib, where a, b ∈ R" [PAPERS]. Anyone who assumed complex loci disappeared in 2023 because they are not in the area-of-study list is reading only half the study design.

What is not here. There is no arg/modulus inequality machinery beyond loci and regions, no complex analysis, no Euler's identity e^{iθ} = cis(θ) as a required form (the study design consistently writes cis, and the formula sheet does likewise — see §3.6), and no roots of unity as a group-theoretic object.

---

1.7 Area of Study 4 — Calculus

This is the largest area of study by examination weight: about 28% of the tagged marks in 2023–2025 November papers ([QJSON]), and about 26% across the whole 2006–2025 archive. It has three named topics.

[SD] overview, verbatim:

"In this area of study students cover the advanced calculus techniques for analytical and numerical differentiation and integration of a broad range of functions, and combinations of functions; and their application in a variety of theoretical and practical situations, including curve sketching, evaluation of arc length, area and volume, differential equations and kinematics, and modelling with differential equations drawing from a variety of fields such as biology, economics and science."

1.7.1 Differential calculus and integral calculus

[SD] content, verbatim (equations linearised from OMML):

This topic includes:
- the relationship between the graph of a function and the graphs of its anti-derivative functions
- derivatives of inverse circular functions
- second derivatives, use of notations f''(x) and d²y/dx², and their application to the analysis of graphs of functions, including points of inflection and concavity
- applications of chain rule to related rates of change and implicit differentiation; for example, implicit differentiation of the relations x² + y² = 9, 3xy² = x + y and x·sin(y) + x²·cos(y) = 1
- techniques of anti-differentiation and for the evaluation of definite integrals:
- anti-differentiation of 1/x to obtain logₑ(x)
- anti-differentiation of 1/√(a² − x²) and a/(a² + x²) for a > 0 by recognition that they are derivatives of corresponding inverse circular functions
- use of the substitution u = g(x) to anti-differentiate expressions
- use of the trigonometric identities sin²(ax) = ½(1 − cos(2ax)) and cos²(ax) = ½(1 + cos(2ax)) in anti-differentiation techniques
- anti-differentiation using partial fractions of rational functions
- integration by parts
- numerical and symbolic integration using technology
- application of integration, areas of regions bounded by curves, arc lengths for parametrically determined curves, surface area of solids of revolution, volumes of solids of revolution of a region about either coordinate axis.

Three of these are new in 2023 (bolded above) and are confirmed as such by VCAA itself. [RPT23 E1]: "New topics tested in 2023 included integration by parts (Question 5), area of a surface of revolution (Question 7) …".

Integration by parts. [SAMPLE] Exam 1 Question 11 is simply "Find ∫ x² cos(2x) dx" (4 marks) — a double application. [RPT23 E1] lists integration by parts among areas of strength in its first live outing, which is unusual for new content and tells you the technique is mechanically learnable and therefore not where a 45+ candidate should be losing marks.

Surface area of revolution. [SAMPLE] Exam 1 devotes four questions (Q6–Q9) to it — rotation about the x-axis, about the y-axis, from parametric equations about the y-axis, and from parametric equations about the x-axis. That is VCAA signalling that all four variants are in scope. Note the formula is supplied on the formula sheet (§3.6), so the difficulty is set-up and by-hand integration, not recall.

Arc length is restricted — and the formula sheet confirms it. The dot point says "arc lengths for parametrically determined curves", and the Outcome 1 key skill repeats the restriction: "curve lengths (where described parametrically)". Correspondingly, the Cartesian arc-length integral ∫√(1 + (dy/dx)²) dx was removed from the formula sheet in 2023 — the 2016–2022 sheet carried both forms; the current sheet carries only ∫_{t₁}^{t₂} √((dx/dt)² + (dy/dt)²) dt (§3.6). This is a clean example of the specification, the content list and the formula sheet all moving together, and it means pre-2023 Cartesian arc-length questions are no longer representative practice.

Implicit differentiation is named with three worked examples, ranging from the trivial circle to x·sin(y) + x²·cos(y) = 1, which needs the product rule twice. 2025 Exam 1 Question 1 (4 marks) is an implicit-differentiation tangent question; [RPT25 E1] records the mark distribution 10/3/27/12/48 and an average of 2.9/4, noting "While the implicit differentiation was often performed successfully, arithmetic errors prevented some students from obtaining the correct gradient" and that "A small number of students who successfully found the value of the gradient at the given point neglected to give the equation of the tangent" — i.e. the loss was not conceptual.

1.7.2 Differential equations

[SD] content, verbatim:

This topic includes:
- formulation of differential equations from contexts in, for example, chemistry, biology and economics, in situations where rates are involved (including some differential equations whose analytic solutions are not required, but can be solved numerically using technology)
- the logistic differential equation
- verification of solutions of differential equations and their representation using direction (slope) fields
- solution of simple differential equations of the form dy/dx = f(x), dy/dx = g(y) and in general differential equations of the form dy/dx = f(x)·g(y) using separation of variables and differential equations of the form d²y/dx² = f(x)
- numerical solution by Euler's method (first order approximation).

The logistic equation is new in 2023. [SAMPLE] Exam 1 Question 10 sets it out in full: dP/dt = 2P(6 − P/8000) — sorry, the extracted text renders this as dP/dt = 2P(6 − P/8000) but the OCR of the sample paper is imperfect in the coefficient; the structure dP/dt = kP(1 − P/M) is what is being tested — with parts asking for the carrying capacity, the population at maximum growth rate (i.e. M/2), and the closed-form solution P(t). Flagging the uncertainty explicitly: the exact constants in [SAMPLE] Exam 1 Q10 could not be read reliably from the text extraction; the PDF should be consulted before this question is reproduced.

The solvable forms are closed. dy/dx = f(x), dy/dx = g(y), dy/dx = f(x)g(y), and d²y/dx² = f(x). Nothing else is required analytically. In particular there are no integrating factors, no linear first-order dy/dx + P(x)y = Q(x), and no second-order equations except the trivially double-integrable d²y/dx² = f(x). Anything harder must come with technology (Exam 2) or with the solution given for verification.

Euler's method is "first order approximation" only — i.e. yₙ₊₁ = yₙ + h·f(xₙ, yₙ). No Runge–Kutta, no improved Euler.

Slope fields are for verification and representation, not for solving. The dot point ties them to "verification of solutions". They appear as multiple-choice matching items.

1.7.3 Kinematics: rectilinear motion

[SD] content, verbatim:

This topic includes:
- use of velocity–time graphs to describe and analyse rectilinear motion
- application of differentiation, anti-differentiation and solution of differential equations to rectilinear motion of a single particle, including the different derivative forms for acceleration a = d²x/dt² = dv/dt = v·dv/dx = d/dx(½v²).

This is the residue of what used to be a full Mechanics area of study. Note the phrase "a single particle". Under the 2023 design there are no connected-particle systems, no pulleys, no inclined planes with friction, no resolution of forces, no Newton's second law as a modelling step, and no momentum. Those were removed at the 2023 transition — see §5.4. The formula sheet's Mechanics block was removed at the same time (§3.6).

But gravity did not disappear. Every Specialist paper, including 2025 Exam 1 and 2025 Exam 2, still carries the front-page instruction: "Take the acceleration due to gravity to have magnitude g m s⁻², where g = 9.8" [PAPERS]. Vertical-motion-under-gravity questions remain squarely in scope as kinematics; [RPT25 E2] on Section A Question 13: "Constant acceleration formulas may be used. However, care must be taken with the signs. Taking upwards as positive then: …".

Constant-acceleration formulas remain on the formula sheet (see §3.6), which is the giveaway that constant-acceleration kinematics is still examinable content rather than merely assumed.

1.8 Area of Study 5 — Space and measurement

Historically the biggest area in the archive (41% of tagged marks 2006–2015, when it absorbed both vectors and mechanics; 21% in 2023–2025). It has three named topics and it is where the 2023 design added the most new machinery.

[SD] overview, verbatim:

"In this area of study students cover the arithmetic and algebra of vectors; linear dependence and independence of a set of vectors; proof of geometric results using vectors; vector representation of curves in the plane and their parametric and Cartesian equations; vector kinematics in one, two and three dimensions; vector, parametric and Cartesian equations of lines and planes."

1.8.1 Vectors

[SD] content, verbatim:

This topic includes:
- addition and subtraction of vectors and their multiplication by a scalar, position vectors
- linear dependence and independence of a set of vectors and geometric interpretation
- magnitude of a vector, unit vector, the orthogonal unit vectors [i, j, k]
- resolution of a vector into rectangular components
- scalar (dot) product of two vectors, deduction of dot product for the [i, j, k] vector system and its use to find scalar resolute and vector resolute
- vector (cross) product of two vectors in three dimensions, including the determinant form
- parallel and perpendicular vectors
- vector proofs of simple geometric results, such as 'the diagonals of a rhombus are perpendicular', 'the medians of a triangle are concurrent' and 'the angle subtended by a diameter in a circle is a right angle'.

Source note. In the two dot points above, the symbols shown in square brackets are rendered in the published DOCX as embedded MathType OLE images, not as text or live equations, so they extract as nothing. Reconstructing them as the standard orthogonal unit vectors i, j, k (VCAA writes them with an under-tilde: i~, j~, k~) is an inference from context and from the formula sheet, which uses exactly that notation. It is a safe inference but it is an inference.

The cross product is new in 2023. [RPT24 E1] confirms: "New topics from 2023 were again tested in 2024. In particular, proofs (Question 2), the cross product (Question 4b and Question 10) and lines in space (Question 10)." The determinant form is explicitly named, and [SAMPLE] Exam 2 Section A Question 3 asks students to identify the correct 3×3 determinant |i j k; …; …| for a vector perpendicular to two given lines. [SAMPLE] Exam 1 Questions 18–19 use the cross product for area: "The position vectors a = 2i + 4j − 2k and b = i − 2j + 3k form two sides of a triangle. Find the area of the triangle in the form c√d, where c, d ∈ N" and a parallelogram-area problem solving for an unknown component.

Vector proofs of geometric results are named with three canonical examples. These three — rhombus diagonals, concurrent medians, angle in a semicircle — are the study design's own list and should be treated as a minimum drill set.

1.8.2 Vector and Cartesian equations

[SD] content, verbatim:

This topic includes:
- vector equations and parametric equations of curves in two or three dimensions involving a parameter (and the corresponding Cartesian equation in the two-dimensional case)
- vector equation of a straight line, given the position of two points, or equivalent information, in both two and three dimensions
- vector cross product, normal to a plane and vector, parametric and Cartesian equations of a plane.

Planes are new in 2023. [RPT23 E1] again: "New topics tested in 2023 included … and planes (Question 9)." [SAMPLE] Exam 1 devotes Questions 12–17 to planes and lines in space, and the list of sub-types is worth memorising because it is VCAA's own statement of scope:

• plane through a point containing two given direction vectors → Cartesian equation (Q12)
• plane through three given points (Q13a)
• intersection of a line r = a + t·d with a plane (Q13b)
• angle between a plane and a line (Q14)
• vector equation of a line through two points, then the sine of the angle it makes with a plane (Q15 — note sine, because the angle between a line and a plane is the complement of the angle between the line and the normal)
• angle between two planes, expressed via sec(θ) (Q17)

[SAMPLE] Exam 2 Section A adds two more: the plane perpendicular to a given normal through a given point (Q5), and the shortest distance between two parallel planes (Q6: 5x − 4y − 12z = 10 and −15x + 12y + 36z = 20). The second of those is a genuinely non-obvious inclusion — note the two planes are parallel because (−15, 12, 36) = −3(5, −4, −12).

2025 Exam 1 Question 2 (3 marks, mark distribution 14/13/15/59, average 2.2 — [RPT25 E1]) is the intersection-of-two-lines-in-space question, and the report's diagnosis is precise and worth quoting to students: "It was common for students to use the same parameter for both lines. This did not result in viable equations to solve. In this case, students were ineligible for full marks."

1.8.3 Vector calculus

[SD] content, verbatim:

This topic includes:
- position vector as a function of time and sketching the corresponding path given the function, including circles, ellipses and hyperbolas in Cartesian or parametric forms
- the positions of two particles each described as a vector function of time, and whether their paths cross or if the particles meet
- differentiation and anti-differentiation of a vector function with respect to time and applying vector calculus to motion in a plane and in three dimensions.

Note the quiet survival of conics. "including circles, ellipses and hyperbolas in Cartesian or parametric forms" — the conic sections were removed as a standalone area of study after 2015, but they re-enter here as paths traced by a vector function of time. A 2023–2027 question can legitimately require you to recognise that r(t) = 3cos(t)i + 2sin(t)j traces the ellipse x²/9 + y²/4 = 1, or that r(t) = sec(t)i + tan(t)j traces x² − y² = 1. What is not in scope is the 2006–2015 apparatus of foci, directrices, eccentricity and asymptote-of-hyperbola-by-formula.

"Whether their paths cross or if the particles meet" is the study design distinguishing two different questions — the paths intersecting (solve for two independent parameters) versus the particles colliding (same parameter value). 2025 Exam 1 Question 5 (4 marks) is exactly this: part (a) "Show that for collision to occur when t = 1, the value of c is −4" [PAPERS].

1.9 Area of Study 6 — Data analysis, probability and statistics

[SD] overview, verbatim:

"In this area of study students cover the study of linear combinations of random variables and introductory statistical inference with respect to the mean of a single population, the determination of confidence intervals, and hypothesis testing for the mean using the distribution of sample means."

1.9.1 Distribution of linear combinations of random variables

[SD] content, verbatim (equations linearised from OMML):

This topic includes:
- for n independent identically distributed random variables X₁, X₂ … Xₙ each with mean μ and variance σ²:
- E(X₁ + X₂ + … + Xₙ) = nμ
- Var(X₁ + X₂ + … + Xₙ) = nσ²
- for n independent random variables X₁, X₂ … Xₙ and real numbers a₁, a₂ … aₙ:
- E(a₁X₁ + a₂X₂ + … + aₙXₙ) = a₁E(X₁) + a₂E(X₂) + … + aₙE(Xₙ)
- Var(a₁X₁ + a₂X₂ + … + aₙXₙ) = a₁²Var(X₁) + a₂²Var(X₂) + … + aₙ²Var(Xₙ)
- for n normally distributed independent random variables X₁, X₂ … Xₙ and real numbers a₁, a₂ … aₙ the random variable a₁X₁ + a₂X₂ + … + aₙXₙ is also normally distributed.

The aᵢ² in the variance rule is the single most examined trap in this topic, together with the distinction between X₁ + X₂ (variance 2σ²) and 2X (variance 4σ²). [RPT23 E1] lists "calculating the mean and standard deviation of the sum of independent random variables (Question 6a.)" among areas of strength, which means it is a mark a 45+ candidate simply must not drop.

1.9.2 Distribution of the sample mean

[SD] content, verbatim:

This topic includes:
- the concept of the sample mean X̄ as a random variable whose value varies between samples where X is a random variable with mean μ and the standard deviation σ
- simulation of repeated random sampling, from a variety of distributions and a range of sample sizes, to illustrate properties of the distribution of X̄ across samples of a fixed size n including its mean μ, its standard deviation σ/√n (where μ and σ are the mean and standard deviation of X respectively) and its approximate normality if n is large.

1.9.3 Confidence intervals for the population mean

[SD] content, verbatim:

This topic includes:
- determination of confidence intervals for means and the use of simulation to illustrate variations in confidence intervals between samples and to show that the likelihood of a confidence interval containing μ depends on the level of confidence chosen in the determination of the interval
- construction of an approximate confidence interval, (x̄ − z·σ/√n, x̄ + z·σ/√n) where σ is the population standard deviation and z is the appropriate quantile for the standard normal distribution, or construction of an approximate confidence interval (x̄ − z·s/√n, x̄ + z·s/√n) where s is the sample standard deviation and z is the appropriate quantile for the standard normal distribution, and n is large (n ≥ 30 in many practical contexts).

Two intervals, two conditions. The σ-known form and the s-estimated form, the latter requiring large n. The study design puts a number on "large": n ≥ 30, hedged as "in many practical contexts". Note VCAA uses the normal quantile in both cases — there is no t-distribution anywhere in VCE Specialist Mathematics.

1.9.4 Hypothesis testing for a population mean

[SD] heading, verbatim: "Hypothesis testing for a population mean with a sample drawn from a normal distribution of known variance, or for a large sample"

[SD] content, verbatim:

This topic includes:
- concepts of null hypothesis, H₀, and alternative hypotheses, H₁, test statistic
- level of significance and p-value
- formulation of hypotheses and making a decision concerning a population mean based on:
- a random sample from a normal population of known variance
- a large random sample from any population
- 1-tail and 2-tail tests
- interpretation of the results of a hypothesis test in the context of the problem
- hypothesis test, relating the formulation, conduct, errors and results in terms of conditional probability.

The last dot point is the deepest one and the one most often skipped. "errors … in terms of conditional probability" means Type I and Type II errors, framed as P(reject H₀ | H₀ true) and P(fail to reject H₀ | H₀ false). VCAA examined this immediately: [SAMPLE] Exam 2 Section A Question 7 gives a machine with μ = 20, σ = 2, a claimed reduction to μ = 18.5, sample size 16, α = 5% with critical sample mean 19.2, and asks for "The probability of a type II error (β) for the test", with options 8%, 34%, 36%, 46%, 95%.

The live papers do the same in extended-response form. 2021 Exam 2 Question 6 (under the previous study design, which also contained hypothesis testing — see §5.3) asks in part (d) "Find the range of values for the mean daily sales of another 14 randomly selected days that would lead to the null hypothesis being rejected when tested at the 1% level of significance" (1 mark), then in part (e) "Find the probability that the null hypothesis would be incorrectly accepted … assuming a standard deviation of 5000" (2 marks) [PAPERS] — a Type II error computation in all but name.

Statistics is the highest-scoring area for the state. In [QJSON], written statistics parts in 2023–2025 have a median full-mark rate of 65%, the highest of any area. [RPT24 E2] lists "applying statistical methods" among areas of strength. This is the area where a 45+ candidate should be banking marks, not fighting for them.

2. The three outcomes

[SD]:

"For each unit the student is required to demonstrate achievement of three outcomes. As a set these outcomes encompass all of the areas of study for each unit. For each of Unit 3 and Unit 4 the outcomes as a set apply to the content from the areas of study covered in that unit."

The same three outcomes apply to Unit 3 and to Unit 4. Each is stated as a single sentence, followed by key knowledge and key skills.

2.1 Outcome 1 — knowledge, routines and procedures

"On completion of this unit the student should be able to define and explain key concepts as specified in the content from the areas of study and apply a range of related mathematical routines and procedures."

"To achieve this outcome the student will draw on key knowledge and key skills outlined in all the areas of study."

Key knowledge, verbatim:

• principles of proof and deduction techniques
• the proof scheme and method for mathematical induction
• functions and relations, the form of their sketch graphs and their key features, including linear asymptotes
• complex numbers, Cartesian and polar forms, operations and properties and representation in the complex plane
• geometric interpretation of vectors in the plane and of complex numbers in the complex plane
• differentiation techniques and the meaning of first and second derivatives of a function
• anti-differentiation techniques, the relationship between the graph of a function and the graph of its anti-derivative functions, and graphical interpretation of definite integrals
• analytical, graphical and numerical techniques for setting up and solving equations involving functions and relations
• modelling contexts for formulation of differential equations and associated solution techniques, including numerical approaches
• definition and properties of vectors, vector operations, the geometric representation of vectors and the geometric interpretation of linear dependence and independence of a set of vectors
• standard contexts for the application of vectors to the motion of a particle and to geometric problems
• techniques for solving kinematics problems in one, two and three dimensions
• the vector product and methods determining vector equations of lines and planes
• systems of equations with two and three variables and their geometric interpretation
• the distribution of sample means

Key skills, verbatim:

• apply deductive reasoning and language, including mathematical induction, to mathematical arguments and proofs involving concepts and contexts from the areas of study
• sketch by hand and describe behaviour of the graphs of specified functions and relations, and identify their key features, including the use of the first and second derivative
• perform operations on complex numbers expressed in Cartesian form or polar form and interpret them geometrically
• Interpret and apply algorithms in a variety of contexts including the use of pseudocode for representation
• represent regions of an Argand diagram using complex relations
• apply implicit differentiation, by hand in simple cases
• use analytic techniques to find derivatives and anti-derivatives by pattern recognition, and apply anti-differentiation to evaluate definite integrals
• set up and evaluate definite integrals to calculate areas, volumes, curve lengths (where described parametrically) and surface areas
• set up and solve differential equations of specified forms
• perform operations on vectors and interpret them geometrically
• apply vectors to motion of a particle and to geometric problems
• solve kinematics problems using a variety of techniques
• formulate problems which require solutions with systems of linear equations
• apply a range of analytical, graphical and numerical processes to obtain solutions (exact or approximate) to equations
• set up and solve problems involving the distribution of sample means
• construct confidence intervals, and approximate confidence intervals, for sample means

(The capitalised "Interpret" in the fourth key skill is VCAA's own typography, reproduced here unaltered.)

Five items in this list appear in no area-of-study dot point and would be invisible to a student who read only the content lists. They are, in effect, hidden scope:

An internal inconsistency in the study design, worth knowing about. The Outcome 1 key knowledge names "the distribution of sample means", and the key skills name "set up and solve problems involving the distribution of sample means" and "construct confidence intervals, and approximate confidence intervals, for sample means" — but hypothesis testing appears in neither list, despite having its own full topic heading in Area of Study 6 (§1.9.4). This is a genuine gap in the document, not an omission from this summary. It does not make hypothesis testing unexaminable: [SPEC] says "All of the content from the areas of study and the key knowledge and key skills that underpin the outcomes in Units 3 and 4 are examinable", and hypothesis testing is content. It has been examined in 2023 Exam 2, 2024 NHT Exam 2, 2025 Exam 2 and 2026 NHT Exam 2 [PAPERS]. But it does mean that, read strictly, the Outcome 1 lists under-describe Examination 1's scope.

2.2 Outcome 2 — non-routine, investigative, modelling and problem-solving

"On completion of this unit the student should be able to apply mathematical processes in non-routine contexts, including situations with some open-ended aspects requiring investigative, modelling or problem-solving techniques or approaches, and analyse and discuss these applications of mathematics."

Key knowledge, verbatim:

• key mathematical content from one or more areas of study related to a given context
• specific and general formulations of concepts used to derive results for analysis within a given context
• the role of examples, counter-examples and general cases in working mathematically
• the role of proof in establishing a general result
• key elements of algorithm design, including sequencing, decision-making and repetition, and representations of the ordered steps for an algorithm including the use of pseudocode
• inferences from analysis and their use to draw valid conclusions related to a given context

Key skills, verbatim:

• specify the relevance of key mathematical content from one or more areas of study to the investigation of various questions in a given context
• identify important information, variables, constraints and other key features to the investigation of various questions in a given context
• develop mathematical formulations of specific and general cases used to derive results for analysis within a given context and establish proofs for general case results
• use algorithms, patterns, models and simulation to solve problems related to a given context
• use a variety of techniques to verify results
• make inferences from analysis and use these to draw valid conclusions related to a given context
• communicate results and conclusions using both mathematical expression and everyday language, in particular, the interpretation of mathematics with respect to the context

Outcome 2 is the outcome Examination 2 emphasises. [SPEC]: "Examination 2 will cover all areas of study in relation to all three outcomes, with an emphasis on Outcome 2." In practice this is what generates the multi-stage Section B question: a context is introduced, a specific case is analysed, the case is generalised (usually with an unspecified parameter), and a final part asks for a conclusion about the model. It is also what licenses the "show that" instruction — "establish proofs for general case results" — which appears on average three to seven times per Exam 2. [RPT23 E2] counted three; [RPT16 E2] counted four; [RPT10 E2] counted seven.

2.3 Outcome 3 — computational thinking and technology

"On completion of this unit the student should be able to apply computational thinking and use numerical, graphical, symbolic and statistical functionalities of technology to develop mathematical ideas, produce results and carry out analysis in situations requiring investigative, modelling or problem-solving techniques or approaches."

Key knowledge, verbatim:

• the role of computational thinking (abstraction, decomposition, pattern and algorithm) in problem-solving, and its application to mathematical investigation
• exact and approximate specification of mathematical information such as numerical data, graphical forms and general or specific forms of solutions of equations produced by technology
• domain and range requirements for specification of graphs of functions and relations, when using technology
• the role of parameters in specifying general forms of functions and equations
• the relation between numerical, graphical and symbolic forms of information about functions and equations, and the corresponding features of those functions and equations
• the similarities and differences between formal mathematical expressions and their representation by technology
• the appropriate functionality of technology for a variety of mathematical contexts

Key skills, verbatim:

• use computational thinking, algorithms, models and simulations to solve problems related to a given context
• distinguish between exact and approximate presentations of mathematical results produced by technology, and interpret these results to a specified degree of accuracy
• produce results, using a technology, which identify examples or counter-examples for propositions
• produce tables of values, symbolic expressions, families of graphs or collections of other results using technology, which support general analysis in investigative, modelling or problem-solving contexts
• use appropriate domain and range specifications to illustrate key features of graphs of functions and relations
• identify the relation between numerical, graphical and symbolic forms of information about functions and equations, and the corresponding features of those functions and equations
• select an appropriate functionality of technology in a variety of mathematical contexts and provide a rationale for these selections
• design and implement simulations and algorithms using appropriate functionalities of technology
• apply suitable constraints and conditions, as applicable, to carry out required computations
• relate the results from a particular technology application to the nature of a particular mathematical task (investigative, modelling or problem-solving) and verify these results
• specify the process used to develop a solution to a problem using technology and communicate the key stages of mathematical reasoning (formulation, solution, interpretation) used in this process

Outcome 3 is assessed in Examination 2 only. [SPEC] states Examination 1 "will cover all areas of study in relation to Outcome 1"; Examination 2 covers "all three outcomes". Since Examination 1 forbids technology, Outcome 3 cannot be assessed there.

How Outcome 3 actually shows up in a paper. Not as a "technology question" but embedded: - domain/range specification when graphing — [RPT25 E2] on Section B Q1a: "To improve accuracy, students can sketch the function on their CAS calculator and set the domain, range and scale to match those provided in the question." - defining variables before using a formula — [RPT25 E2] on Q1b.i: "Students must make sure variables are defined if they are being used in formulas." - selecting the right functionality — [RPT25 E2] on Section A Q11: "Use the DEsolve functionality on CAS to solve the given differential equation and then find the domain of the solution. Alternatively, use separation of variables to solve the differential equation manually." And on Q2: "CAS can be used to determine this in the algebra menu, or students could use the graphing menu to see the shape of the graph." - exact vs approximate — [RPT24 E2]: "Answers must be left in exact form unless a specific number of decimal places is required." - algorithms and pseudocode — the Section A pseudocode items described in §2.1.

2.4 How the outcomes map onto assessment

[SD] SAC detail, verbatim:

• Unit 3 (50 marks) — a single Application task: "A mathematical investigation of a practical or theoretical context involving content from two or more areas of study, with the following three components of increasing complexity: introduction of the context through specific cases or examples; consideration of general features of the context; variation or further specification of assumption or conditions involved in the context to focus on a particular feature or aspect related to the context." Duration: "The application task is to be of 4–6 hours' duration over a period of 1–2 weeks."
• Unit 4 (50 marks) — Modelling or problem-solving tasks 1 and 2, with marks split (Outcome 1: 8 + 7; Outcome 2: 10 + 10; Outcome 3: 7 + 8). "One of the modelling or problem-solving tasks is to address the Data analysis, probability and statistics area of study. Each modelling or problem-solving task is to be of 2–3 hours' duration over a period of 1 week."

Note the asymmetry with General Mathematics. In Specialist, the two SACs are worth 20% each and the examinations 20% + 40%, so the examinations carry 60% of the study score and Examination 2 alone carries twice the weight of Examination 1. In General Mathematics the split is 24/16/30/30. A Specialist student who is strong under exam conditions is rewarded more, and Examination 2 is the single highest-stakes assessment in the subject.

3. Examination structure

3.1 Overall conditions

[SPEC], verbatim, in order:

"There will be two end-of-year examinations for VCE Specialist Mathematics – examination 1 and examination 2."

"The examination will be sat at a time and date to be set annually by the Victorian Curriculum and Assessment Authority (VCAA). VCAA examination rules will apply."

"Examination 1 will have 15 minutes of reading time and 1 hour of writing time. Students are not permitted to bring into the examination room any technology (calculators or software) or notes of any kind."

"Examination 2 will have 15 minutes of reading time and 2 hours of writing time. Students are permitted to bring into the examination room an approved technology with numerical, graphical, symbolic and statistical functionality, as specified in the VCAA Notices to Schools and the VCE Exams Navigator. One bound reference (which may be annotated) may also be brought into the examination room. This may be a textbook, a securely bound lecture pad, an exercise book or a permanently bound student-constructed set of notes without foldouts. Specifications for the bound reference are published annually in the VCE Exams Navigator."

"A Formula Sheet will be provided with both examinations."

"The examination will be assessed by a panel appointed by the VCAA."

"Examination 1 will contribute 20 per cent to the study score. Examination 2 will contribute 40 per cent to the study score."

3.2 Content scope, verbatim from the specifications

[SPEC]:

"The VCE Mathematics Study Design (From 2023) ('Units 3 and 4: Specialist Mathematics') is the document for the development of the examination. All outcomes in 'Units 3 and 4: Specialist Mathematics' will be examined."

"All of the content from the areas of study and the key knowledge and key skills that underpin the outcomes in Units 3 and 4 are examinable."

"Examination 1 will cover all areas of study in relation to Outcome 1. The examination is designed to assess students' knowledge of mathematical concepts, their skill in carrying out mathematical algorithms without the use of technology, and their ability to apply concepts and skills."

"Examination 2 will cover all areas of study in relation to all three outcomes, with an emphasis on Outcome 2. The examination is designed to assess students' ability to understand and communicate mathematical ideas, and to interpret, analyse and solve both routine and non-routine problems."

3.3 Examination 1 — format

[SPEC], verbatim:

• "The examination will be in the form of a Question and Answer Book."
• "The examination will consist of short-answer and extended-answer questions."
• "All questions will be compulsory. The total marks for the examination will be 40."
• "A Formula Sheet will be provided with the examination. The Formula Sheet will be the same for examinations 1 and 2."
• "Answers are to be recorded in the spaces provided in the Question and Answer Book."

Approved materials and equipment, Examination 1 [SPEC]:

• "Basic stationery requirements (pens, pencils, highlighters, erasers, sharpeners and rulers)"

That is the complete list. No protractor, no set squares, no curve-sketching aids, no calculator of any kind, no notes.

What the papers themselves say. 2025 Exam 1 cover page [PAPERS]:

"Students are not permitted to bring any technology (calculators or software) or notes of any kind into the examination room."
"Students are not permitted to bring mobile phones and/or any unauthorised electronic devices into the examination room."
"Materials supplied • Question and Answer Book of 12 pages • Formula Sheet"
"Reading time is 15 minutes: 9.00 am to 9.15 am / Writing time is 1 hour: 9.15 am to 10.15 am"

Number of questions. [SPEC] does not fix a question count, only the 40-mark total. The archive shows the count drifting between 8 and 11:

Source: [PAPERS] structure tables; 2024 from [RPT24 E1] ("The 2024 VCE Specialist Mathematics Examination 1 comprised 10 questions worth a total of 40 marks"), because the 2024 text extraction is empty. The 2026 NHT paper has 11 questions.

Marks per question therefore vary from 1 to about 7. The practical planning number is 1.5 minutes per mark (60 minutes ÷ 40 marks).

Instructions page, verbatim (2025 Exam 1, [PAPERS]; wording essentially unchanged since 2016):

• "Answer all questions in the spaces provided."
• "Write your responses in English."
• "Unless otherwise specified, an exact answer is required for each question."
• "In questions where more than one mark is available, appropriate working must be shown."
• "Unless otherwise indicated, the diagrams in this book are not drawn to scale."
• "Take the acceleration due to gravity to have magnitude g m s⁻², where g = 9.8"

3.4 Examination 2 — format

[SPEC], verbatim:

• "The examination will be in the form of a Question and Answer Book."
• "The examination will consist of two sections."
• "Section A will consist of 20 multiple-choice questions worth 1 mark each and will be worth a total of 20 marks."
• "Section B will consist of short-answer and extended-answer questions, including multi-stage questions of increasing complexity, and will be worth a total of 60 marks."
• "All questions will be compulsory. The total marks for the examination will be 80."
• "A Formula Sheet will be provided with the examination. The Formula Sheet will be the same for examinations 1 and 2."
• "Answers to Section A are to be recorded on the Multiple-Choice Answer Sheet."
• "Answers to Section B are to be recorded in the spaces provided in the Question and Answer Book."

Approved materials and equipment, Examination 2 [SPEC], verbatim:

• "Basic stationery requirements (pens, pencils, highlighters, erasers, sharpeners and rulers)"
• "Protractors, set squares and aids for curve sketching"
• "An approved technology with numerical, graphical, symbolic and statistical functionality"
• "One scientific calculator"
• "One bound reference"

Note the plurals and singulars. "Protractors, set squares and aids for curve sketching" — plural, unlimited. "One scientific calculator", "One bound reference", "An approved technology" — each singular. Across the entire 2006–2026 archive the phrase "two bound references" never appears; it has always been one [PAPERS].

Section B question count. [SPEC] does not fix it. In practice it has been six in every November paper from 2016 onward except one:

• 2020 November Exam 2 had five Section B questions (12 + 11 + 10 + 14 + 13 = 60 marks) [PAPERS]. This is the only post-2016 November exception.
• 2018 NHT Exam 2 had seven (10 + 11 + 10 + 11 + 9 + 5 + 4 = 60) [PAPERS].

Individual Section B questions run 9–14 marks; 10 marks is the modal value in the current era (2025 Exam 2 Section B: 10, 9, 10, 10, 10, 10).

Section A option count changed in 2024 — the most recent structural change, and easy to miss.

Evidence: [RPT23 E2]'s Section A table has columns "% A, % B, % C, % D, % E"; [RPT24 E2]'s and [RPT25 E2]'s have only "% A, % B, % C, % D". The official Sample Multiple-Choice Answer Sheet, Specialist Mathematics Examination 2 (October 2025, corpus/sm/text/2025-10_MCAS_SpecialistMaths2.txt) prints exactly four boxes — "A B C D" — for each of questions 1 to 20, with the instruction "All answers must be completed like this example: A B C D". The 2025 Exam 2 paper body confirms it: every Section A question ends at option D.

Consequences for a 45+ candidate. Random guessing rises from 20% to 25% expected. More importantly, distractor design gets tighter: with one fewer option, each remaining distractor must carry more weight, and the pattern in [RPT24 E2]/[RPT25 E2] is that a single dominant distractor now frequently splits the cohort nearly evenly with the key. 2025 Exam 2 Question 12 is the extreme case: 33% chose A, 33% chose the correct answer D [RPT25 E2]. 2024 Exam 2 Question 2: 48% chose the correct A, 37% chose D [RPT24 E2].

Section A instructions, verbatim (2025 Exam 2, [PAPERS]):

• "Answer all questions in pencil on your Multiple-Choice Answer Sheet."
• "Choose the response that is correct for the question."
• "A correct answer scores 1; an incorrect answer scores 0."
• "Marks will not be deducted for incorrect answers."
• "No marks will be given if more than one answer is completed for any question."
• "Unless otherwise indicated, the diagrams in this book are not drawn to scale."
• "Take the acceleration due to gravity to have magnitude g m s⁻², where g = 9.8"

There is no negative marking. Never leave a Section A item blank.

Section B instructions, verbatim (2025 Exam 2, [PAPERS]) — identical in substance to Exam 1's:

• "Answer all questions in the spaces provided."
• "Write your responses in English."
• "Unless otherwise specified, an exact answer is required for each question."
• "In questions where more than one mark is available, appropriate working must be shown."
• "Unless otherwise indicated, the diagrams in this book are not drawn to scale."
• "Take the acceleration due to gravity to have magnitude g m s⁻², where g = 9.8"

The wording has been stable since at least 2019 — compare 2019 Exam 2's "Instructions for Section B": "Unless otherwise specified, an exact answer is required to a question. In questions where more than one mark is available, appropriate working must be shown." [PAPERS]

Time budget. 120 minutes for 80 marks = 1.5 minutes per mark, the same rate as Exam 1. The conventional split is 30 minutes for Section A, 90 minutes for Section B. [RPT10 E2] makes the point explicitly: "It is important that students plan their time so they can tackle the multiple-choice and the extended answer sections effectively."

3.5 Reading time

Fifteen minutes on both papers, every year from 2006 to 2026 [PAPERS]. Nothing may be written during reading time.

Under the 2006–2015 regime the formula sheet was bound into the centre of the Question and Answer Book, and the instruction read "Detach the formula sheet from the centre of this book during reading time" (2006 Exam 1, [PAPERS]). From 2016 the Formula Sheet has been a separately supplied document, with the note "You may keep the formula sheet" (2016–2023) or, from 2024, "You may keep this Formula Sheet" printed on the sheet itself.

3.6 The Formula Sheet — exactly what is on it

Header, verbatim (2024–2026 booklet form, from corpus/sm/text/Documents_exams_mathematics_specmaths1-formula-w.txt):

"Specialist Mathematics / Examination 1 / 2024 Formula Sheet / You may keep this Formula Sheet. / © VCAA 2024"

with running heads "Formula Sheet VCE Specialist Mathematics Examination 1" and footer "End of Formula Sheet / © Victorian Curriculum and Assessment Authority 2024". The current sheet is 8 pages (the 2024 NHT variant is 4 pages).

The 2023 sheet used the older cover style, verbatim:

"Victorian Certificate of Education 2023 / SPECIALIST MATHEMATICS / Written examination 1 / FORMULA SHEET / Instructions / This formula sheet is provided for your reference. / A question and answer book is provided with this formula sheet. / Students are NOT permitted to bring mobile phones and/or any other unauthorised electronic devices into the examination room. / © VICTORIAN CURRICULUM AND ASSESSMENT AUTHORITY 2023"

The sheet is identical for Examination 1 and Examination 2, as [SPEC] promises. Verified by diffing the two published sheets: the files differ on exactly seven lines, every one of which is the string "Examination 1" versus "Examination 2" in a title or running head. This has been true in every era — the 2006–2015 sheet was literally a single document headed "Written examinations 1 and 2".

Section order on the current sheet: Mensuration → Algebra, number and structure (complex numbers) → Data analysis, probability and statistics → Calculus → Calculus – continued → Kinematics → Vectors in two and three dimensions → Circular functions. There is no "Coordinate geometry" section and no "Mechanics" section.

Transcription caveat. The corpus text extractions of the formula sheet lose minus signs, radicals, fraction bars, π and ≤, because the PDFs use Symbol/MT-Extra fonts. The formulas below are reconstructed from the surviving token order, cross-checked against the 2019 and 2012 sheets (which do preserve minus signs) and against mathematical necessity. Which formulas are present or absent is certain; the rendering of a particular sign or radical is reconstructed. The cross-product determinant and the parametric plane equations are the two most badly mangled blocks and their exact bracketing should be checked against the PDF before reproduction.

Data analysis, probability and statistics

For independent random variables X₁, X₂ … Xₙ: - E(aX₁ + b) = a·E(X₁) + b - E(a₁X₁ + a₂X₂ + … + aₙXₙ) = a₁E(X₁) + a₂E(X₂) + … + aₙE(Xₙ) - Var(aX₁ + b) = a²·Var(X₁) - Var(a₁X₁ + a₂X₂ + … + aₙXₙ) = a₁²Var(X₁) + a₂²Var(X₂) + … + aₙ²Var(Xₙ)

For independent identically distributed X₁, X₂ … Xₙ: - E(X₁ + X₂ + … + Xₙ) = nμ - Var(X₁ + X₂ + … + Xₙ) = nσ²

Approximate confidence interval for μ: - (x̄ − z·s/√n, x̄ + z·s/√n)

Distribution of the sample mean X̄: - E(X̄) = μ - Var(X̄) = σ²/n

Calculus — standard derivatives and antiderivatives

Not present: ∫tan(ax) dx; ∫logₑ(x) dx; the derivative of aˣ; any partial-fraction template.

Calculus – continued

• product rule: d(uv)/dx = u·dv/dx + v·du/dx
• quotient rule: d/dx(u/v) = (v·du/dx − u·dv/dx)/v²
• chain rule: dy/dx = dy/du × du/dx
• integration by parts: ∫u(dv/dx) dx = uv − ∫v(du/dx) dx
• Euler's method: "If dy/dx = f(x, y), x₀ = a and y₀ = b, then x_{n+1} = xₙ + h and y_{n+1} = yₙ + h × f(xₙ, yₙ)."
• arc length (parametric only): ∫_{t₁}^{t₂} √((dx/dt)² + (dy/dt)²) dt
• surface area, Cartesian, about the x-axis: ∫_{x₁}^{x₂} 2πy√(1 + (dy/dx)²) dx
• surface area, Cartesian, about the y-axis: ∫_{y₁}^{y₂} 2πx√(1 + (dx/dy)²) dy

• surface area, parametric, about the y-axis: ∫_{t₁}^{t₂} 2πx√((dx/dt)² + (dy/dt)²) dt

Not present: the Cartesian arc length ∫√(1 + (dy/dx)²) dx (removed in 2023 — the 2016–2022 sheet had it); the volume of revolution π∫y² dx (never on any sheet, in any era).

Kinematics

• acceleration: a = d²x/dt² = dv/dt = v·dv/dx = d/dx(½v²)
• constant acceleration: v = u + at; s = ut + ½at²; v² = u² + 2as; s = ½(u + v)t

Vectors in two and three dimensions

• r(t) = x(t)i + y(t)j + z(t)k
• |r(t)| = √(x(t)² + y(t)² + z(t)²)
• ṙ(t) = dr/dt = (dx/dt)i + (dy/dt)j + (dz/dt)k

For r₁ = x₁i + y₁j + z₁k and r₂ = x₂i + y₂j + z₂k: - scalar (dot) product: r₁·r₂ = |r₁||r₂|cos(θ) = x₁x₂ + y₁y₂ + z₁z₂ - vector (cross) product: r₁ × r₂ = det[i j k; x₁ y₁ z₁; x₂ y₂ z₂] = (y₁z₂ − y₂z₁)i + (x₂z₁ − x₁z₂)j + (x₁y₂ − x₂y₁)k - vector equation of a line: r(t) = r₁ + t·r₂ - parametric equations of a line: x(t) = x₁ + x₂t, y(t) = y₁ + y₂t, z(t) = z₁ + z₂t - vector equation of a plane: r(s, t) = r₀ + s·r₁ + t·r₂ - parametric equations of a plane: x(s,t) = x₀ + x₁s + x₂t, y(s,t) = y₀ + y₁s + y₂t, z(s,t) = z₀ + z₁s + z₂t - Cartesian equation of a plane: ax + by + cz = d

Not present, in any era: scalar resolute a·b̂ and vector resolute (a·b̂)b̂. A search for the string "resolute" across all corpus files finds it only in question stems and reports (e.g. 2026 NHT Exam 2, 2016 Exam 1), never on a formula sheet. Also absent: the unit vector â = a/|a|; |a × b| as a parallelogram area; the scalar triple product; the distance from a point to a plane; the angle between two planes; vector projection.

Circular functions

• cos²(x) + sin²(x) = 1
• 1 + tan²(x) = sec²(x)
• cot²(x) + 1 = cosec²(x)
• sin(x ± y) = sin(x)cos(y) ± cos(x)sin(y)
• cos(x ± y) = cos(x)cos(y) ∓ sin(x)sin(y)
• tan(x ± y) = (tan(x) ± tan(y))/(1 ∓ tan(x)tan(y))
• sin(2x) = 2sin(x)cos(x)
• cos(2x) = cos²(x) − sin²(x) = 2cos²(x) − 1 = 1 − 2sin²(x)
• tan(2x) = 2tan(x)/(1 − tan²(x))
• sin²(ax) = ½(1 − cos(2ax))
• cos²(ax) = ½(1 + cos(2ax))

Present but incomplete: the Pythagorean identities involving sec, cosec and cot are given, but the definitions sec(x) = 1/cos(x), cosec(x) = 1/sin(x), cot(x) = cos(x)/sin(x) are not.

Not present: the inverse circular function domain/range table (removed in 2023 — the 2016–2022 sheet carried it); product-to-sum and sum-to-product formulas; exact values; the a sin(x) + b cos(x) = R sin(x + α) compression.

The memorisation list

Twelve things a 2023–2027 candidate must carry in their head because they are demonstrably not on the sheet:

1. Scalar resolute a·b̂ and vector resolute (a·b̂)b̂
2. Domains and ranges of sin⁻¹, cos⁻¹, tan⁻¹
3. Cartesian arc length ∫√(1 + (dy/dx)²) dx
4. Volume of revolution π∫y² dx and π∫x² dy
5. The test statistic z = (x̄ − μ)/(σ/√n) and all hypothesis-testing apparatus
6. Euler's formula e^{iθ} = cis(θ)
7. Heron's formula; circle sector area and arc length; area and circumference of a circle
8. sec = 1/cos, cosec = 1/sin, cot = cos/sin
9. ∫tan(ax) dx, ∫logₑ(x) dx
10. Unit vector â; |a × b| as area; point-to-plane distance; angle between two planes
11. E(X) and Var(X) definitions, and Var(X) = E(X²) − [E(X)]²
12. Momentum p = mv and R = ma — removed from the sheet in 2023, consistent with the removal of mechanics (§5.4); but note the papers still instruct "Take the acceleration due to gravity to have magnitude g m s⁻², where g = 9.8", so vertical-motion kinematics remains live.

Note on the bound reference. Items 1–11 are things to put in the bound reference for Examination 2. For Examination 1 they must be memorised outright, since no reference is permitted.

4. What each examination can and cannot ask

4.1 The specification's own constraints

[SPEC] closes with an "Advice" section, verbatim:

"From 2023, the VCE Specialist Mathematics examinations will be prepared according to the examination specifications above. Each examination will conform to these specifications and will test a representative sample of the key knowledge and key skills from all outcomes in Units 3 and 4."

"Students should use command/task words, other instructional information within questions and corresponding mark allocations to guide their responses."

"Separate documents containing sample questions have been published on the VCE Specialist Mathematics 'Examination specifications, past examinations and examination reports' page on the VCAA website."

"The sample questions provide an indication of the types of questions teachers and students can expect until the current accreditation period is over."

"Answers to multiple-choice questions are provided on page 15 of the sample questions document for examination 2. Answers to other questions are not provided."

Three operational consequences:

1. "A representative sample" means no single examination covers everything. Content can be absent from a paper without being out of scope. Predicting the next paper from the last paper's omissions is a real strategy — but a weak one, because "representative" is assessed across both papers together, not within one.
2. "Command/task words … and corresponding mark allocations to guide their responses" is VCAA telling you the mark count is a specification of how much working is required. [RPT24 E2] restates it: "The number of marks allocated to a question indicates the level of detail required in the response. Answers without supporting work will not earn method marks."
3. The sample-question documents are part of the specification apparatus, not optional extras. They are the only place VCAA showed what the 2023 content would look like before it was examined, and the four surface-area variants and the six plane/line variants in [SAMPLE] Exam 1 remain the clearest statement of scope for those topics.

4.2 Examination 1: what it can ask

It can ask anything in the study design, but only "in relation to Outcome 1" and only in a form that can be done without technology. In practice:

• implicit differentiation and related rates (2025 Exam 1 Q1, average 2.9/4; 2016 Exam 1 Q3, listed in [RPT16 E1] as a strength)
• by-hand sketching of rational and quotient functions with asymptotes, stationary points and points of inflection ([RPT23 E1] lists Q1b as an area of strength)
• antidifferentiation by recognition, substitution, partial fractions, trigonometric identity, and integration by parts ([RPT23 E1]: "New topics tested in 2023 included integration by parts (Question 5)")
• separable differential equations and d²y/dx² = f(x)
• Euler's method with two or three steps and friendly numbers
• complex arithmetic in Cartesian and polar form; factorisation over C; the conjugate root theorem
• vector dot and cross products, lines and planes in 3D (2025 Exam 1 Q2; [RPT24 E1] Q4b and Q10)
• proof by induction, contradiction, contrapositive (2023 Exam 1 Q8; 2026 NHT Exam 1 Q2)
• E and Var of linear combinations; the X̄ distribution; confidence intervals with a friendly z ([RPT23 E1] lists Q6a as a strength)
• surface-area and arc-length set-up, then by-hand evaluation of the resulting integral

Structurally constrained by being technology-free. Every number on an Exam 1 paper is chosen so the arithmetic closes. If you find yourself needing a calculator, you have made an error or taken the wrong route. [RPT24 E1] says as much: "Students completed this examination without the use of a CAS or references other than the standard formula sheet supplied with the examination paper. Algebraic and arithmetic errors were often seen."

It can ask you to recall a formula that is not on the sheet. [RPT24 E1], verbatim: "Formulas from the formula sheet were occasionally used incorrectly (for example, the derivative in Question 9b). Students may also have needed to recall or derive a formula (Question 10)." This is the most explicit statement VCAA has made that the formula sheet is not sufficient, and it is the practical justification for the memorisation list in §3.6.

4.3 Examination 1: what it cannot ask

An important nuance. Exam 1 can ask a question whose full solution would ordinarily be done on CAS, provided the numbers are rigged. It regularly does: Exam 1 confidence-interval questions choose z = 1.96 or z = 2 with a perfect-square n; Exam 1 induction questions choose divisors that factor cleanly. The constraint is arithmetic tractability, not topic.

4.4 Examination 2: what it can ask, and where technology is expected

[SPEC]: Examination 2 "is designed to assess students' ability to understand and communicate mathematical ideas, and to interpret, analyse and solve both routine and non-routine problems", covering all three outcomes "with an emphasis on Outcome 2".

Technology is not optional; it is assumed. [SD]: "Student access to an approved technology with numerical, graphical, symbolic and statistical functionality will be assumed." The reports read, in places, like CAS instruction manuals. From [RPT25 E2] Section A alone:

And in Section B, [RPT25 E2]:

• Q1a (sketching): "To improve accuracy, students can sketch the function on their CAS calculator and set the domain, range and scale to match those provided in the question."
• Q1b.i: "Students must make sure variables are defined if they are being used in formulas."
• Q1b.ii: "This is obtained using CAS with the equation from part 1b.i."

The four places technology is effectively mandatory in Section B:

1. Solving equations with no closed form (transcendental roots; intersections of a line and a curve).
2. Definite integrals that cannot be done by hand — arc lengths, surface areas, and most volumes of revolution in context.
3. Differential equations of the "analytic solution not required" kind. The study design explicitly licenses these: "including some differential equations whose analytic solutions are not required, but can be solved numerically using technology."
4. Statistical computation — invNorm for a z quantile, the normal CDF for a p-value, and simulation (both the sample-mean and confidence-interval dot points name simulation explicitly).

Where technology is a trap. [RPT25 E2]'s "Areas for improvement" is explicit: "Exact answers are expected unless told otherwise." [RPT24 E2]: "Answers must be left in exact form unless a specific number of decimal places is required." A CAS decimal where an exact surd was required scores zero for that mark even if the underlying work is correct. [RPT16 E2] records the converse error too: "a few students moved from a correct exact answer to an incorrect decimal approximation in Question 1e. or gave an exact answer where a decimal approximation was required in Question 5c."

An additional trap specific to graph questions. [RPT25 E2]: "It is also important to take care when graphing. Students should set up their CAS calculators to match the given scale and make sure the shape is accurate, including asymptotic behaviour. When asked to sketch a graph on polar axes, make sure the solution is clear and visible. Graphs should also be drawn using pencil to enable incorrect responses to be erased."

4.5 Examination 2: what it cannot ask

What it is not barred from asking, contrary to common belief: questions that are entirely by-hand. Many Section B parts are indistinguishable from Exam 1 items — [RPT23 E2] notes three "show that" questions in that paper ("Questions 1a., 2fii. and 5a."). Technology availability is a permission, not an instruction.

4.6 The "show that" contract

This deserves isolating, because it is where high-scoring students most often drop marks through under-writing.

[RPT25 E2], verbatim: "'Show that' questions require clear steps of working that lead to the given answer."

[RPT24 E1], verbatim: "There were several questions that required students to show that a particular result was obtained. In such questions, full marks will only be awarded where appropriate and correct working is provided."

[RPT23 E2], verbatim: "There were three questions (Questions 1a., 2fii. and 5a.) for which students needed to show that a given result would emerge. In these cases, steps that led to the given result needed to be clearly and logically set out to attract full marks."

[RPT11 E2], verbatim, on the related "verify" instruction: "Model answers were seen where x(t) was substituted into the left side of the differential equation, followed by clear algebraic steps showing that the left side simplified to give the right side. Other unsatisfactory approaches involved substituting into the whole differential equation, particularly rearrangements of it, along with the omission of the key simplifying steps."

Frequency. "Show that" and "verify" questions appear on essentially every paper: [RPT10 E2] counted seven in Section 2; [RPT15 E2] counted five; [RPT16 E2] counted four; [RPT23 E2] counted three. Three to seven per Exam 2 is the right planning assumption.

Why they matter disproportionately. Because the answer is given, these questions are reachable even if you cannot do the algebra — and therefore they are scored strictly on the working shown. They are also load-bearing: a "show that" part typically supplies the result later parts depend on, so a student who cannot prove it can still use it. Never skip the rest of a question because you could not establish its "show that".

4.7 Presentation rules that carry marks

Collected verbatim from the reports, because every one has cost the state marks:

• [RPT25 E2]: "Students should ensure that their responses are not difficult to read. Students are reminded to either write in pen or use a dark lead, 2B or similar. It is also important that the writing is clear, not written over another response and is in the right size to fit inside the given space."
• [RPT24 E2]: "To ensure their work is clearly visible when scanned, students should write using a pen or a dark lead pencil. Additionally, legible handwriting is crucial; several responses were difficult to read." (Papers are scanned for online marking — faint pencil is effectively invisible to an assessor.)
• [RPT25 E2]: "If the question asked for equations of asymptotes or other similar equations, then the responses must be written as individual equations." (i.e. x = 2 and y = 3, not "asymptotes at 2 and 3".)
• [RPT16 E1]: "Students should be reminded that if an assessor is not certain as to what an answer is conveying, that assessor cannot award marks… If there are inconsistencies in the student's working, full marks cannot be awarded. For example, if an equals sign is placed between quantities that are not equal, full marks cannot be awarded."
• [RPT11 E1]: "Working should not appear to be a number of disjointed statements."
• [RPT25 E1], on 2025 Exam 1 Q1: "A small number of students who successfully found the value of the gradient at the given point neglected to give the equation of the tangent at that point and were not awarded full marks."
• [RPT25 E1], on 2025 Exam 1 Q2: "It was common for students to use the same parameter for both lines. This did not result in viable equations to solve. In this case, students were ineligible for full marks."
• [RPT24 E2]: "Students must carefully read the questions and ensure their answers comply with the stated conditions."

5. How the assessment has changed, 2005–2026

The site draws on an archive spanning four different assessment regimes. This section states exactly what changed and when, so that a question from any year can be classified as still in scope, in scope but differently formatted, or out of scope.

5.1 The four regimes at a glance

Sources: [PAPERS] structure tables and cover pages, 2006–2026; [RPT06 E1], [RPT06 E2]; [SPEC]; [SD].

5.2 Pre-2006: a multiple-choice Examination 1

[RPT06 E1], verbatim, is the only description of the old format in the corpus:

"The new structure for examination 1 started in 2006. Previously, students were required to answer 30 multiple-choice questions in Part I, and five short answer questions worth a total of 20 marks in Part II. In 2006 students were required to answer nine short and extended answer questions worth a total of 40 marks. No calculators, CAS or notes of any kind were permitted in the examination. Due to the change in the structure of the examination, where practicable the comparisons given below are of students' performance on the short answer parts of the respective examinations; that is, with respect to Part II of examination 1 in 2005 and the entire paper in 2006."

[RPT06 E2], verbatim:

"The number of students who sat the 2006 examination was 5210, compared to 5625 in 2005. This year was the first of the new structure in which students answered 22 multiple-choice questions, and then five extended answer questions. The time allowed – two hours for the exam, which allowed students access to notes – seemed adequate."

No pre-2006 papers are in the corpus. The 2005 and earlier examinations are not usable for practice in their original form, and their structure (a 30-item multiple-choice Part I) has no modern counterpart.

One useful data point survives from that era. [RPT06 E1] records the 2005 whole-paper mean as 30.2/50 (60.4%) with a median of 31/50 (62%), against 21.8/40 (54.4%) for the new-format 2006 Examination 1. Replacing a 30-item multiple-choice section with short answer dropped the paper mean by about six percentage points, which is the clearest single illustration in the archive of how much multiple-choice inflates a mean.

5.3 2006–2015: the 22-question era

Structure. Examination 2 comprised Section 1: 22 multiple-choice questions, 22 marks and Section 2: five extended-answer questions, 58 marks, total 80 [PAPERS], confirmed year by year in the reports ([RPT13 E2]: "The 2013 Specialist Mathematics examination 2 comprised 22 multiple-choice questions (worth 22 marks) and five…"; [RPT15 E2]: "…comprised 22 multiple-choice questions (worth a total of 22 marks) and five extended-answer questions (worth a total of 58 marks)"). Examination 1 was 40 marks in 8–11 questions.

Terminology. Sections were numbered ("Section 1", "Section 2"), not lettered. The 2006 Examination 2 is internally inconsistent about this: its heading reads "Instructions for Section I" in Roman numerals while the structure table and running head say "SECTION 1" [PAPERS].

Permitted materials, verbatim [PAPERS]:

• 2006–2009: "Students are permitted to bring into the examination room: pens, pencils, highlighters, erasers, sharpeners, rulers, a protractor, set-squares, aids for curve sketching, one bound reference, one approved graphics calculator or approved CAS calculator or CAS software and, if desired, one scientific calculator. Calculator memory DOES NOT need to be cleared."
• 2010–2015: identical except that the graphics-calculator option was dropped — "…one bound reference, one approved CAS calculator or CAS software and, if desired, one scientific calculator."

So 2010 is the year CAS became compulsory for Specialist Mathematics Examination 2; before that a plain graphics calculator was still legal.

Not permitted, Examination 1 [PAPERS]: 2006–2014, "notes of any kind, a calculator of any type, blank sheets of paper and/or white out liquid/tape". From 2015 the wording became "correction fluid/tape".

5.3.1 The 2006–2015 areas of study, verbatim

Source and caveat. Quoted from [SD06] — the 2005-published, 2006–2009-accredited edition, Specialist Mathematics Units 3 and 4, printed pp. 207–212. The 2010–2015 reaccredited reissue could not be located. The 2010 reissue is known to have dropped the non-CAS Mathematical Methods units; whether any Specialist Units 3 and 4 dot point changed at that point is unverified. Indirect reassurance: the examination content in the corpus is stable from 2006 to 2015 with no visible discontinuity at 2010. Because [SD06] is a scan with no text layer, the quotations are a manual transcription; the prose is reliable, individual mathematical symbols less so. The original genuinely uses lower-case "de moivre's theorem", "euler's method", "argand diagram", "newtonian" and "cartesian".

[SD06], verbatim:

"Specialist Mathematics consists of the following areas of study: 'Functions, relations and graphs' 'Algebra', 'Calculus', 'Vectors' and 'Mechanics'."

That is five areas of study. The unit split, [SD06]:

"In Unit 3 a study of Specialist Mathematics would typically include content from 'Functions, relations and graphs' and a selection of material from the 'Algebra', 'Calculus' and 'Vectors' areas of study. In Unit 4 this selection would typically consist of the remaining content from the 'Algebra', 'Calculus', and 'Vectors' areas of study and the content from the 'Mechanics' area of study."

A common misconception, corrected. There is no 'Coordinate geometry' area of study, no 'Circular functions' area of study and no 'Probability' area of study in the 2006–2015 design. "Coordinate geometry" and "Circular (trigonometric) functions" are formula-sheet headings, not areas of study. Conics and circular functions both sit inside 'Functions, relations and graphs'. (Those formula-sheet headings most likely descend from the pre-2006 design, for which no primary source was located.)

Formula-sheet headings by era, which corroborate the area-of-study changes from an independent direction [PAPERS]:

The conics dot points, verbatim [SD06], because these are the single largest block of dead questions in the archive:

"sketch graphs of ellipses from the general cartesian relation (x − h)²/a² + (y − k)²/b² = 1"

"sketch graphs of hyperbolas (including asymptotic behaviour) from the general cartesian relation (x − h)²/a² − (y − k)²/b² = 1; these do not involve consideration of focus-directrix properties"

Note that even in 2006–2015, foci, directrices and eccentricity were explicitly excluded. Conics were a graph-sketching topic, not a classical-geometry topic.

Three further 2006–2015 restrictions worth knowing, all [SD06]:

• Concavity was explicitly excluded: "(treatment of concavity is not required)". It became required in 2016.
• Differential equations were a closed list: "dy/dx = f(x), d²y/dx² = f(x), dy/dx = g(y) where g(y) is a linear or quadratic function of y, or a reciprocal of one of these, or g(y) = √(a² − y²)". General separation of variables dy/dx = f(x)g(y) was not available until 2016.
• Mechanics included friction and statics: "This area of study covers statics and an introduction to newtonian mechanics"; "…concurrent coplanar forces, including frictional forces; sliding friction and the coefficient of friction"; "This includes consideration of limiting equilibrium when the body is at rest."
• Complex-plane relations had their own sub-heading with four dot points covering lines and rays; circles, ellipses and other familiar simple curves; combinations of the above; and regions defined through those curves. Note that ellipses in the complex plane were dropped in 2016 and have not returned.

Content distinctive to this era (evidenced by the formula sheet and by grep over the papers):

Difficulty. [QJSON]: written parts in this era had a median full-mark rate of 47%, multiple-choice a median correct rate of 63%. 23% of written parts and 3% of multiple-choice items fell below a 30% success rate.

5.4 2016–2022: statistics in, conics and friction out, 22 → 20

The structural change is sharp and dates precisely to 2016.

[RPT15 E2]: "The 2015 Specialist Mathematics examination 2 comprised 22 multiple-choice questions (worth a total of 22 marks) and five extended-answer questions (worth a total of 58 marks)." [RPT16 E2]: "The 2016 Specialist Mathematics examination 2 comprised 20 multiple-choice questions (worth a total of 20 marks) and six extended-answer questions (worth a total of 60 marks)."

The 2015 paper's multiple-choice section runs to Question 22; the 2016 paper's stops at Question 20 [PAPERS].

Permitted materials wording changed at the same time, [PAPERS] 2016–2023:

"Students are permitted to bring into the examination room: pens, pencils, highlighters, erasers, sharpeners, rulers, a protractor, set squares, aids for curve sketching, one bound reference, one approved technology (calculator or software) and, if desired, one scientific calculator. Calculator memory DOES NOT need to be cleared. For approved computer-based CAS, full functionality may be used."

And on Examination 1, the prohibition was tightened from "a calculator of any type" to the broader "any technology (calculators or software)".

The formula sheet changed in four ways (formula-sheet diff, [PAPERS]):

• ADDED: a whole Probability and statistics section — E(aX + b), E(aX + bY), var(aX + b), var(aX + bY), the approximate confidence interval, and the distribution of the sample mean. Also arc length in both Cartesian and parametric forms, and ṙ = dr/dt in Vectors.
• REMOVED: the entire Coordinate geometry section (ellipse and hyperbola equations); friction F ≤ μN; the constant-acceleration formulas.
• RENAMED: "Circular (trigonometric) functions" became "Circular functions".
• REPACKAGED: from one sheet headed "Written examinations 1 and 2", detached from the centrefold during reading time, to two separately printed sheets with identical content and the note "You may keep the formula sheet".

What this means content-wise:

The precise 2016 content changes, [SD06] against [OLDSD]:

And what did not change in 2016, contrary to a common claim: De Moivre's theorem, factorisation over C, the fundamental theorem of algebra and the conjugate root theorem are present in all three designs — with the same worked examples (z⁸ + 1, z² − i, z³ − (2 − i)z² + z − 2 + i) carried verbatim from 2006 through to the current design. nth roots of unity are not named in [SD06] (they are covered by "powers and roots of complex numbers in polar form") but are named from 2016 and have been examined in every era — 2013, 2015, 2020, and 2023 Exam 2 Section B Q2 (z⁷ − 1 = 0) [PAPERS].

5.4.1 The 2016–2022 areas of study, verbatim

Source and caveat. The following is quoted from the VCE Mathematics Study Design for the 2016–2022 accreditation period, "Specialist Mathematics Units 3 and 4", obtained as the "Adjusted Study Design for 2020 only" reissue. That reissue marks COVID-era deletions in red strikethrough, which do not survive plain-text extraction. Treat the dot points below as the 2016–2022 content list, but be aware that a small amount of it was struck out for the 2020 cohort specifically — the 2020 formula sheet's missing statistics section (§5.7) is direct evidence that the 2020 adjustment cut into this content. Tag: [OLDSD].

[OLDSD], verbatim:

"Specialist Mathematics Units 3 and 4 consist of the areas of study: 'Functions and graphs', 'Algebra', 'Calculus', 'Vectors' and 'Mechanics' and 'Probability and statistics'."

That is six areas of study, not five. The unit split, [OLDSD]:

"In Unit 3 a study of Specialist Mathematics would typically include content from 'Functions and graphs' and a selection of material from the 'Algebra', 'Calculus' and 'Vectors' areas of study. In Unit 4 this selection would typically consist of the remaining content from the 'Algebra', 'Calculus', and 'Vectors' areas of study and the content from the 'Mechanics' and 'Probability and statistics' areas of study."

And the assumed-knowledge statement, which is the key to the proof question below, [OLDSD]:

"Specialist Mathematics Units 3 and 4 assumes familiarity with the key knowledge and skills from Mathematical Methods Units 1 and 2, the key knowledge and skills from Specialist Mathematics Units 1 and 2 topics 'Number systems and recursion' and 'Geometry in the plane and proof', and concurrent or previous study of Mathematical Methods Units 3 and 4."

Area of Study 1 — Functions and graphs, [OLDSD]:

"In this area of study students cover inverse circular functions, reciprocal functions, rational functions and other simple quotient functions, the absolute value function, graphical representation of these functions, and the analysis of key features of their graphs including intercepts, asymptotic behaviour and the nature and location of stationary points, points of inflection, periodicity, and symmetry."

This area of study includes:
- graphs of rational functions of low degree, their asymptotic behaviour and nature and location of stationary points
- absolute value function, its graph and simple transformations of the graph
- graphs of the reciprocal circular functions cosecant, secant and cotangent, and simple transformations of these
- compound and double angle formulas for sine, cosine and tangent and the identities: sec²(x) = 1 + tan²(x) and cosec²(x) = 1 + cot²(x)
- graphs of the restricted circular functions of sine, cosine and tangent over principal domains and their respective inverse functions sin⁻¹, cos⁻¹ and tan⁻¹ (students should be familiar with alternative notations) and simple transformations of these graphs
- graphs of simple quotient functions.

This is the largest single content loss at the 2023 transition. The current 'Functions, relations and graphs' area of study (§1.5) contains three dot points — rational functions, partial fractions, and simple quotient functions. The absolute value function, the graphs of cosec/sec/cot, the graphs of the restricted circular functions and their inverses, and the compound and double-angle formulas as graphing content are all gone from it. (The double-angle and power-reduction identities survive as antidifferentiation tools in the current AoS 4 and are on the formula sheet; the inverse circular functions survive as derivatives and antiderivatives in AoS 4. What has gone is the graphing and transformation treatment.)

Area of Study 2 — Algebra, [OLDSD]:

"In this area of study students cover the expression of simple rational functions as a sum of partial fractions; the arithmetic and algebra of complex numbers, including polar form; points and curves in the complex plane; introduction to factorisation of polynomial functions over the complex field; and an informal treatment of the fundamental theorem of algebra."

Rational functions of a real variable, including:
- definition of a rational function and expression of rational functions of low degree as sums of partial fractions.

Complex numbers, including:
- C, the set of numbers z of the form z = x + yi where x, y are real numbers and i² = −1, real and imaginary parts, complex conjugates, modulus
- use of an argand diagram to represent points, lines, rays and circles in the complex plane
- equality, addition, subtraction, multiplication and division of complex numbers
- polar form (modulus and argument); multiplication and division in polar form, including their geometric representation and interpretation, proof of basic identities involving modulus and argument
- De Moivre's theorem, proof for integral powers, powers and roots of complex numbers in polar form, and their geometric representation and interpretation
- nth roots of unity and other complex numbers and their location in the complex plane
- factors over C of polynomials with integer coefficients; and informal introduction to the fundamental theorem of algebra
- factorisation of polynomial functions of a single variable over C, for example, z⁸ + 1, z² − i, z³ − (2 − i)z² + z − 2 + i
- solution over C of corresponding polynomial equations by completing the square, factorisation and the conjugate root theorem.

What changed in complex numbers at the 2023 transition — this is narrower than commonly claimed:

Area of Study 3 — Calculus, [OLDSD]. The differential- and integral-calculus dot points are almost word-for-word the current ones, with these differences:

• "application of integration, arc lengths of curves, areas of regions bounded by curves and volumes of solids of revolution of a region about either coordinate axis." Note "arc lengths of curves" — unrestricted, Cartesian or parametric. The current design restricts this to "arc lengths for parametrically determined curves" and adds "surface area of solids of revolution" (§1.7.1).
• No integration by parts. The technique list stops at partial fractions.
• No logistic differential equation. The differential-equations list has formulation, verification and slope fields, the same solvable forms, and Euler's method — nothing more.
• Kinematics is identical: rectilinear motion of a single particle, the same a = d²x/dt² = dv/dt = v dv/dx = d/dx(½v²) chain, and velocity–time graphs.

Area of Study 4 — Vectors, [OLDSD]:

"In this area of study students cover the arithmetic and algebra of vectors, linear dependence and independence of a set of vectors, proof of geometric results using vectors, vector representation of curves in the plane and vector kinematics in one and two dimensions."

Vectors, including:
- addition and subtraction of vectors and their multiplication by a scalar, and position vectors
- linear dependence and independence of a set of vectors and geometric interpretation
- magnitude of a vector, unit vector, and the orthogonal unit vectors i, j and k
- resolution of a vector into rectangular components
- scalar (dot) product of two vectors, deduction of dot product for i, j, k system; its use to find scalar and vector resolutes
- parallel and perpendicular vectors
- vector proofs of simple geometric results, for example the diagonals of a rhombus are perpendicular, the medians of a triangle are concurrent, the angle subtended by a diameter in a circle is a right angle.

Vector calculus, including:
- position vector as a function of time r(t); and sketching the corresponding path given r(t), including circles, ellipses and hyperbolas in cartesian or parametric forms
- differentiation and anti-differentiation of a vector function with respect to time and applying vector calculus to motion in a plane including projectile and circular motion.

Four differences from the current design, all of them consequential:

1. No vector (cross) product. It is entirely absent. This is why [RPT24 E1] calls it a new topic.
2. No planes and no lines in space. Absent. Also new in 2023.
3. Vector kinematics was "in one and two dimensions"; the current design says "vector kinematics in one, two and three dimensions", and the Outcome 1 key knowledge says "techniques for solving kinematics problems in one, two and three dimensions" (§2.1) where the 2016–2022 Outcome 1 said "in one and two dimensions".
4. "including projectile and circular motion" was a named application. The current Vector calculus dot point drops that phrase, saying only "applying vector calculus to motion in a plane and in three dimensions" — projectile motion as a named context is gone, though nothing forbids a projectile context for a kinematics question.

Note that "the positions of two particles each described as a vector function of time, and whether their paths cross or if the particles meet" is new in 2023 as a named dot point (§1.8.3), though the archive contains plenty of pre-2023 questions of that shape.

Area of Study 5 — Mechanics, [OLDSD], in full — this is the area that no longer exists:

"In this area of study students cover an introduction to Newtonian mechanics, for both constant and variable acceleration."

This area of study includes:
- inertial mass, momentum, including change of momentum (conservation of momentum and impulse are not required), force, resultant force, weight, action and reaction
- equations of motion using absolute units (Equations of motion should be described from a diagram, showing all the forces acting on the body, and then writing down the equation of motion. Extensions could include cases involving a system of two or more connected particles. Examples are to be restricted to rectilinear motion, including motion on an inclined plane.)
- motion of a body, regarded as a particle under the action of concurrent coplanar forces (the case of equilibrium should be regarded as an application, where net force is zero).

And the corresponding Outcome 1 key knowledge item, [OLDSD]: "Newton's laws of motion and related concepts."

All of this is out of scope from 2023. It maps precisely onto the corpus evidence: 2019 Exam 2 Q13 (resultant of two forces), 2019 Exam 2 Q14 (a three-mass pulley system — "a system of two or more connected particles"), 2022 Exam 1 Q5b (a braking force on an inclined plane — "including motion on an inclined plane"), all of which are now dead questions.

Note also that the 2016–2022 design already excluded conservation of momentum and impulse — "(conservation of momentum and impulse are not required)" — which is why the corpus contains zero hits for "conservation of momentum" in any paper [PAPERS].

Area of Study 6 — Probability and statistics, [OLDSD]:

"In this area of study students cover statistical inference related to the definition and distribution of sample means, simulations and confidence interval."

Linear combinations of random variables, including:
- for random variables X and Y, E(aX + b) = aE(X) + b and E(aX + bY) = aE(X) + bE(Y)
- for random variables X and Y, Var(aX + b) = a²Var(X) and for independent random variables X and Y, Var(aX + bY) = a²Var(X) + b²Var(Y)
- for independent random variables X and Y with normal distributions then aX + bY also has a normal distribution.

Sample means, including:
- concept of the sample mean X̄ as a random variable whose value varies between samples…
- simulation of repeated random sampling… including its mean μ and its standard deviation σ/√n… and its approximate normality if n is large.

Confidence intervals for means, including:
- determination of confidence intervals for means and the use of simulation to illustrate variations in confidence intervals between samples and to show that most but not all confidence intervals contain μ
- construction of an approximate confidence interval (x̄ − z·s/√n, x̄ + z·s/√n), where s is the sample standard deviation and z is the appropriate quantile for the standard normal distribution, in particular the 95% confidence interval as an example of such an interval where z ≈ 1.96 (the term standard error may be used but is not required).

Hypothesis testing for a population mean with a sample drawn from a normal distribution of known variance or for a large sample, including:
- p values for hypothesis testing related to the mean
- formulation of a null hypothesis and an alternative hypothesis
- errors in hypothesis testing.

So hypothesis testing was already there. The 2023 changes to statistics are therefore precise and limited:

A separate, important question: was formal proof in the 2016–2022 design? The answer is now precise: proof existed, but in Specialist Units 1 and 2, not in Units 3 and 4. [OLDSD]'s assumed-knowledge sentence names the Units 1 and 2 topic "Geometry in the plane and proof" as assumed for Units 3 and 4, and the Units 3 and 4 areas of study contain no proof techniques beyond the two incidental mentions above ("proof of basic identities involving modulus and argument"; "proof for integral powers" of De Moivre; "vector proofs of simple geometric results"). There is no induction, no proof by contradiction, no contrapositive, no quantifiers and no counter-examples anywhere in the 2016–2022 Units 3 and 4 content. The 2023 design promoted proof from assumed Units 1 and 2 knowledge to a Units 3 and 4 area of study in its own right, and thereby made it examinable.

The corpus corroborates this exactly. The words "induction", "contradiction" and "contrapositive" appear in no Specialist Mathematics examination paper before 2023. A case-insensitive search across all 2006–2022 papers returns zero hits for all three [PAPERS]. Proof-by-induction, proof-by-contradiction and contrapositive questions first appear in the January 2023 sample-question documents and then in the 2023 papers. This is the single most important scope change for anyone drilling the pre-2023 archive: there is no legacy proof practice to be had.

(Two caveats on that search: the 2011 papers are unsearchable because of the font-encoding defect described in §0.2, and the search is for the words, not the concepts — a "show that" or "prove that" instruction attached to an algebraic identity is common throughout the archive. What is absent before 2023 is the named proof technique as an examinable object.)

Difficulty. [QJSON]: written parts had a median full-mark rate of 49%, multiple-choice 60%. The multiple-choice got harder relative to the previous era: 33% of items were answered correctly by fewer than half the state, up from 23%.

5.5 2023–2027: proof and number in, mechanics out, vectors expanded

The current design changed content substantially while leaving the examination shape untouched — same 40-mark Examination 1, same 20 + 60 Examination 2.

5.5.1 What VCAA itself says was new

[RPT23 E1], verbatim:

"New topics tested in 2023 included integration by parts (Question 5), area of a surface of revolution (Question 7), proof by induction (Question 8) and planes (Question 9). While some students had difficulty with proof by induction, a majority of students were able to demonstrate that they understood what was required in the questions on the new topics."

[RPT24 E1], verbatim:

"New topics from 2023 were again tested in 2024. In particular, proofs (Question 2), the cross product (Question 4b and Question 10) and lines in space (Question 10). It was pleasing to see that many students were able to partially or fully answer these questions."

5.5.2 Added in 2023

5.5.3 Removed in 2023

5.5.4 Retained across the 2023 transition

Everything else. In particular: complex numbers including polar form, de Moivre, factorisation over C and the conjugate root theorem; regions and relations in the Argand diagram (via the Outcome 1 key skill, and demonstrated in [SAMPLE] Exam 2 Section B Q1 and in the 2025 and 2026 papers, where "Argand" still appears); rational and quotient function sketching; implicit differentiation and related rates; all the antidifferentiation techniques; separable differential equations, slope fields and Euler's method; volumes of revolution; vector geometry proofs; vector calculus and motion in a plane; the whole of statistical inference including hypothesis testing, which was not new in 2023 — it was already being examined in 2021 Exam 2 Q6 [PAPERS].

A correction to a common belief. It is often said that hypothesis testing was introduced to Specialist Mathematics in 2023. The corpus contradicts this: 2021 Exam 2 Question 6 is a full hypothesis-testing question including a Type II error calculation, and "null hypothesis" appears in the 2017 NHT, 2021 November, 2021 NHT and 2022 NHT papers — all under the 2016–2022 design [PAPERS]. What 2023 changed in statistics is narrower: the linear-combination content generalised from two random variables to n, i.i.d. sums were added explicitly, and simulation was written into the study design's dot points.

5.5.5 Difficulty in the current era

[QJSON]: written parts have a median full-mark rate of 56%, up from 47–49% in both earlier eras, and the proportion of very hard written parts (under 30% full marks) has fallen from ~24% to 14%. The multiple-choice has not followed: its median correct rate is 59%, and a third of items are still answered correctly by fewer than half the state. The current design's examinations are, on the state's own performance, more accessible in the extended-response sections than either predecessor.

5.6 2024: five options became four

Already covered structurally in §3.4. Placed here for the timeline: from the 2024 November examination onward, every Section A question offers four options (A–D) rather than five. Evidence: [RPT23 E2]'s Section A table has a "% E" column; [RPT24 E2]'s and [RPT25 E2]'s do not. The October 2025 official Multiple-Choice Answer Sheet prints four boxes per question [PAPERS].

This was not accompanied by any change to the specifications document, which still reads simply "Section A will consist of 20 multiple-choice questions worth 1 mark each" [SPEC]. It is a production change, not a specification change — which is why it is easy to miss.

Practical consequence for drilling. Every multiple-choice question in the archive before 2024 has a fifth option that no longer exists. When reusing them, either delete a distractor or accept that the item is slightly easier than a modern one. Percentage data from pre-2024 items is not directly comparable to post-2024 items for the same reason.

5.7 Cross-era anomalies that will bite an unwary user of the archive

1. The 2020 cohort had the entire statistics area of study removed. This is not a formula-sheet quirk; it is a content deletion. [OLDSD] is the "Adjusted Study Design for 2020 only" print, and its opening sentence shows the sixth area of study struck out: the base text reads "…'Vectors' and 'Mechanics' and 'Probability and statistics'", with the final clause deleted for 2020. Correspondingly:

• Documents_exams_mathematics_2020_2020specmath1-w.txt and ...specmath2-w.txt carry the 2016–2022 formula sheet with the entire "Probability and statistics" section deleted — the sheet jumps straight from Algebra to Calculus [PAPERS].
• Every statistics search term (sample mean, confidence interval, hypothesis test) returns hits in the papers for 2016–2019 and 2021–2022 and zero for 2020 [PAPERS].

A student practising the 2020 papers is practising a course with no statistics in it at all. Since statistics is now roughly 18–20% of the marks (§1.9, [QJSON]), the 2020 papers are the least representative in the whole archive.

2. The 2023 NHT papers use the OLD formula sheet. Documents_exams_mathematics_2023_NHT_2023SM1-nht-w.txt and ...SM2-nht-w.txt carry the 2016–2022 sheet verbatim, including the Mechanics block with momentum p = mv and R = ma [PAPERS]. The first NHT paper with the current sheet is 2024 NHT. Consistently, the 2023 NHT papers still contain mechanics language ("tension in the string", "newtons") that the 2023 November papers do not.

So the 2023 NHT papers are 2016–2022-design papers, not current-design papers, and should be filed with the legacy material. The 2023 November papers are the first true 2023–2027 examinations. Conversely the 2024 NHT papers are new-design — they contain the cross product, induction and planes.

The correct filter for any archive tool is therefore not the calendar year:

A naive year >= 2023 filter will wrongly classify the 2023 NHT papers as current, and will serve students mechanics questions that cannot be examined.

3. Two other data hazards. The 2011 papers extract with a shifted font encoding and are invisible to text search (the PDFs are fine). The 2024 November paper text files are empty; use the PDFs or the 2024 reports.

5.8 Which archive questions are still worth doing

This is the practical output of §5. Classification of legacy question types against the 2023–2027 design.

Fully in scope — drill freely from 2006 onward

In scope, but under-represented in the legacy archive

Out of scope — do not drill

Named dead questions — a citation list

If you are building a "do not attempt" filter, these are real, verified examples of out-of-scope questions in the archive [PAPERS].

Conics (dead since 2016):

• 2015 Exam 2 Section A Q1 — "The ellipse (x − 2)²/9 + (y − 3)²/4 = 1 can be expressed in parametric form as…"
• 2015 Exam 2 Section A Q3 — "If both a and c are non-zero real numbers, the relation a²x² + (1 − a²)y² = c² cannot represent… a circle / an ellipse / a hyperbola…"
• 2015 Exam 2 Section A Q4 — hyperbola from asymptote gradients ±2/3 intersecting at (2, 1)
• 2014 Exam 2 Section A Q1 — asymptotes of (x − 3)²/9 − y²/4 = 1
• 2014 Exam 2 Section A Q2 — centre and semi-axes of x² − 6x + 2y² + 8y + 16 = 0
• 2012 Exam 2 Section A Q2 — ellipse inscribed in a rectangle
• 2010 Exam 2 Section A Q1, Q2 — ellipse semi-axes; identifying hyperbolas
• 2009 Exam 2 Section A Q2, Q5 — intersections of an ellipse and a hyperbola; completing the square for an ellipse centre

Mechanics (dead since November 2023):

• 2022 Exam 2 Section A Q15 — three forces N, T, W on a mass on a smooth inclined plane
• 2022 Exam 2 Section A Q17 — change in momentum of a 7 kg particle
• 2022 Exam 2 Section A Q20 — two masses over a frictionless pulley
• 2022 Exam 1 Q5 (3 marks) — 10 kg body sliding down a smooth plane with tan θ = 1/3
• 2021 Exam 2 Section A Q14 — net force on a 5 kg body with v = 3 + 2x (variable force)
• 2021 Exam 2 Section A Q15 — equilibrium under four forces
• 2021 Exam 2 Section B Q5 (10 marks) — mass on a 30° incline over a frictionless pulley
• 2019 Exam 2 Section A Q13, Q14 — resultant of two forces; 4 kg / 2 kg / 1 kg pulley system
• 2019 Exam 1 Q9 — tension T in terms of m, g, θ
• 2017 Exam 2 Section A Q14, Q16, Q17 — equilibrium on two inclines; momentum after 5 s against a 20 N friction force; resultant of 10 N and 8 N at 60°
• 2016 Exam 2 Section A Q13, Q14, Q15, Q17 — acceleration from forces; ratio of string tensions; variable force with v = 3 − x²; change in momentum
• 2023 NHT Exam 2 Section A Q15, Section B Q3d ("Find, in newtons, the minimum and maximum reaction forces that the floor of the lift exerts on the student") and Section B Q5 — the last mechanics ever set in Specialist Mathematics
• 2015 Exam 2 Section A Q19, Q21, Q22 — pulley system; block on a rough horizontal plane; ball thrown upward against gravity and air resistance (resisted motion was already out of scope from 2016)

Friction as an examinable quantity (dead since 2016): 2012 Exam 2 Section A Q21–Q22 and the 2010 rough-plane questions using μ.

A useful contrast: still in scope, and easy to mistake for a dead question

2021 Exam 1 Q9 gives r(t) = (1 + 4cos(t))i + 2sin(t)j and s(t) = (3sec(t) − 1)i + tan(t)j — an ellipse and a hyperbola, but as paths traced by vector functions of time. That is exactly what the current AoS 5 Vector calculus dot point licenses: "sketching the corresponding path given the function, including circles, ellipses and hyperbolas in Cartesian or parametric forms" (§1.8.3). Drill this style; skip the 2006–2015 conic-as-graph-object style. The distinction is whether the conic arrives as r(t) or as a general Cartesian relation to be analysed.

6. Mark distribution, grading and scaling

Sources for this section. VCAA Score aggregation (VCE Administrative Handbook), VCAA Statistical moderation, VCAA VCE FAQ – Current students, VCAA Section 2 and Section 3 statistics for Specialist Mathematics 2023–2025, VTAC Scaling Report 2023/2024/2025, VTAC ATAR and Scaling Guide 2026, plus [QJSON] and [RPT] from the corpus. Full URLs are tabulated at the end of this section.

6.1 The four graded assessments and their weights

[SD], "Levels of achievement — Units 3 and 4", verbatim:

Specialist Mathematics
Unit 3 School-assessed Coursework: 20 per cent
Unit 4 School-assessed Coursework: 20 per cent
Units 3 and 4 Examination 1: 20 per cent
Units 3 and 4 Examination 2: 40 per cent.

VCAA reports these as three graded assessments, not four — the two coursework components are combined into a single GA:

A scale-factor caveat that matters when reading VCAA's statistics. VCAA's published GA maxima (80 and 160) are exactly twice the raw mark totals printed on the papers (40 and 80). The same 2× relationship holds in Mathematical Methods (40→80, 80→160), General Mathematics (40→80, 60→120) and Chemistry (120→240). VCAA does not state this rule anywhere on its statistics sheets, so the conversion is an inference — but it is a strongly supported one, and §6.4 shows it reproducing the corpus reconstruction to within a tenth of a mark.

Compared with the other mathematics studies: Mathematical Methods uses the identical 20/20/20/40 split. General Mathematics uses 24/16/30/30. Specialist and Methods therefore put 60% of the study score on the two examinations, with Examination 2 alone worth twice Examination 1.

6.2 How raw marks become a study score

VCAA, Score aggregation, verbatim:

"The final score for each graded assessment is standardised. This is done by subtracting the state mean for a graded assessment from the student's final score for that graded assessment, and dividing the result by the state standard deviation for the graded assessment: standardised score = (final score − state mean) / state standard deviation"

"The standardised score for each graded assessment is multiplied by its percentage contribution to the study score… Student-weighted standardised scores are added together. For VCE studies, up to 3 weighted standardised scores are added together. The weighted totals of all students in the study are ranked in descending order. When students have the same total, they are given the group's highest rank… The ranks are then normalised using an inverse normal function. The scores resulting from this transformation are distributed normally, with a mean of zero and a standard deviation of one. The normalised scores are then converted to a scale with a mean of 30 and standard deviation of 7, truncated at zero and 50. This produces a possible study score ranging from zero to 50, with most study scores between 23 and 37."

Read that carefully, because it changes how you should think about a raw mark. The study score is a rank transformation, not a mark transformation. Your raw marks matter only insofar as they determine where you sit in the state's rank order. There is no fixed raw score that "is" a 45. A raw 62/80 on Examination 2 is a different study score contribution in a year when the state mean is 46 than in a year when it is 53.

Grades. VCAA, Score aggregation: "Levels of performance in graded assessments are reported as A+ to E, UG (ungraded) and NA (not assessed)." UG means "the score achieved was too low to assign a grade". To receive a study score at all a student must "achieve 2 or more graded assessments in the study and receive an S for both Units 3 and 4 in the same academic year."

Statistical moderation of the SAC. VCAA, Statistical moderation, verbatim:

"Statistical moderation compares and aligns the level and spread of each school's assessments of its students in a particular study against a common scale."

"All students in a study sit the same external assessment, typically an examination. Examination scores therefore provide a common scale for measuring student achievement… In studies with two examinations, scores from both examinations will be used."

"The scale of the external scores is aligned with the scale of the school-based assessment marks from each school. The alignment is done separately for each moderation group. The student's rank order, as determined by the school-based assessment mark, is preserved. The scores are determined for both the school-based assessment scale and the external score scale: the highest achievement, the upper quartile, the median and the lower quartile. These scores are used as fixed points for aligning the two scales."

"Any adjustment to a student's score is determined by the external scores for the whole group, not by the student's own external score."

"The moderation process is not influenced by students with anomalously low external performances."

Three practical consequences for a 45+ candidate:

1. Your SAC rank within your school is what your school controls; the level and spread come from your cohort's exam performance. You cannot raise your own moderated SAC score by doing well on the exam — only your group's aggregate exam performance moves the scale. What your own exam performance does is move your GA2 and GA3 scores, which are 60% directly.
2. Being ranked first in a weak cohort caps you. The top of your school's moderated SAC scale is pinned to the top of your group's external scale.
3. Both examinations feed moderation, so a poor Examination 1 damages the study score twice: once through GA2 (20%) and again through its contribution to the moderation scale for GA1 (40%).

6.3 The published study-score distribution

VCAA, VCE FAQ – Current students, verbatim:

"Each year, and for every study, the mean study score is set at 30. A score of between 23 and 37 shows that you are in the middle range of students; a score of 38 or more indicates that you are in the top 15%. For studies with large enrolments (1,000 or more):
- 2% of students will get a score on or above 45
- 9% of students will get a score on or above 40
- 26% of students will get a score on or above 35
- 53% of students will get a score on or above 30
- 78% of students will get a score on or above 25
- 93% of students will get a score on or above 20."

Specialist Mathematics Unit 3 enrolment is around 3,600–4,100 (§6.7), so it sits comfortably in the "1,000 or more" band and the table applies as written.

A published inconsistency, flagged rather than resolved. VCAA's 2024 Reference guide to the senior secondary completion and achievement information describes a study score of 40+ as "among the top eight per cent in the state", while the FAQ above says 9% are "on or above 40". The two documents genuinely disagree by a percentage point. Use VCAA's exact phrasing — "on or above 40" — rather than "above 40", and treat 8–9% as the honest range.

So: a study score of 45 in Specialist Mathematics means being in roughly the top 2% of a cohort of about 4,000 — around the 80th-ranked student in the state. A study score of 50 is the top handful.

Per-study study-score distributions are not published. VCAA releases GA grade distributions (§6.5) but not study-score distributions per study; those are available to schools only through the VCE Data Service. Any site claiming "you need X raw marks for a 45 in Specialist" is extrapolating, not quoting.

6.4 Typical mean marks — and a cross-validation

VCAA does not put a paper-level mean in its examination reports (full-text search of the 2023–2025 reports confirms this: the reports carry per-question mark distributions with an "Average" column, and per-option percentages for Section A, and nothing at paper level). It does publish a mean, standard deviation and median for each graded assessment in the annual Section 3 grade-distribution sheets.

VCAA's published GA statistics for Specialist Mathematics:

Halving these (the 2× inference from §6.1) gives the paper means:

Now compare with the independent reconstruction from [QJSON] — built purely from the per-question mark distributions in the examination reports, with no knowledge of the GA statistics:

The two methods agree to within 0.1 of a mark on five of six figures. (The 2025 Exam 2 gap of 0.5 is explained: the corpus extraction of that paper's Section B recovers 59 of the 60 marks.) This simultaneously validates the [QJSON] reconstruction and confirms the 2× GA scale inference.

Reconstructed paper means, 2006–2025 ([QJSON], November sittings; VCAA's own published figure shown where it exists):

† marks a year where the corpus extraction is incomplete (2012 Section A recovered 20 of 22 items; 2022 Exam 1 recovered 38 of 40 marks and Exam 2 recovered 77 of 80; 2025 Exam 2 Section B recovered 59 of 60). Those rows are slightly understated.

What the table tells a 45+ candidate:

• Examination 1 has sat at 55–62% of the paper for twenty years, with two conspicuous crashes (2008 at 46%, 2017 at 50%) and one spike (2013 at 64%). The mean is remarkably stable across all three study designs. The 2023 content redesign did not make Examination 1 harder for the state.
• Examination 2 is normally 54–62%, with one genuine outlier: 2021 at 41%, driven almost entirely by Section B (22.7 out of 60, or 38%). That was the second COVID-disrupted cohort. 2014 (67%) and 2025 (65%) are the two easiest papers in the archive. [RPT25 E2] says so in its own words: "This examination was accessible for the majority of students; few questions were classified as hard or very hard."
• Section A is where the state's marks have quietly declined. Under the 22-question format the mean was 12.3–14.7 out of 22 (56–67%). Under the 20-question format it has been 9.7–12.7 out of 20 (49–64%), and it fell below 55% in four of the ten years 2016–2025. The multiple-choice section is no longer the free-marks section it was in 2006–2010.

6.5 Grade distributions

VCAA's published grade distributions for Specialist Mathematics, percentage of the cohort in each grade band:

GA2 — Written Examination 1

GA3 — Written Examination 2

GA1 — School-assessed Coursework (Units 3 and 4)

Two observations worth internalising.

1. About 7.5% of the state gets A+ on each examination, and about 18% gets A or A+. Since ~2% get a study score of 45 or more, an A+ on one paper is necessary but nowhere near sufficient. A 45+ profile is, roughly, A+ on both examinations and A+ on coursework.
2. The coursework distribution is shaped completely differently from the examinations. Median B+ every year, with ~57% at B+ or above, against a median of C+ on both examinations. Moderation aligns each school's spread to the external scale, but the state aggregate for GA1 still sits well above the exam distributions. In practice this means coursework is a weak discriminator at the top — almost everyone chasing 45+ has an A or A+ on GA1 — and the entire separation happens on the two examinations.

6.6 Where the state's marks actually fall

This is what [QJSON] is uniquely good for: 1,469 graded question parts, each with VCAA's published percentage of the state earning full marks.

6.6.1 Difficulty by era

The current design's written questions are measurably more accessible than either predecessor, while the multiple-choice has got harder. The written median rose from 47–49% to 56%, and the proportion of brutally hard parts (<30% full marks) fell from ~24% to 14%. Meanwhile the fraction of multiple-choice items answered correctly by fewer than half the state rose from 23% to 33% and has stayed there.

6.6.2 Exam 1 versus Exam 2

For written parts 2016–2025: Examination 1 median full-mark rate 46%; Examination 2 Section B median 55%. Examination 1 is the harder paper per mark, despite being worth half as much. The reason is structural: no CAS, no reference, and 1.5 minutes per mark on content that must be executed exactly.

6.6.3 Difficulty rises with mark value — steeply

Written parts, 2016–2025 [QJSON]:

A 3-mark part is, on the state's evidence, roughly half as likely to be fully earned as a 1-mark part. The five-mark parts are near-lottery: fewer than one student in six banks all five.

6.6.4 Difficulty rises through a Section B question

Median full-mark rate by part letter, Exam 2 Section B, 2016–2025 [QJSON]:

The decline from (a) to (e) is monotonic and steep — a 32-percentage-point drop. VCAA's "multi-stage questions of increasing complexity" [SPEC] is not a figure of speech.

But the whole paper does not get harder. Median full-mark rate by Section B question number, 2016–2025:

Section B is shaped like a shallow U: Q1 and Q6 are the most accessible, Q3 and Q4 the hardest. The single most common tactical error in Specialist Exam 2 is running out of time before Question 6, which is on average as accessible as Question 1. If you are behind at the 90-minute mark, skip forward.

6.6.5 Examination 1 is shaped differently — it gets harder to the end

Median full-mark rate by question number, Exam 1, 2016–2025 [QJSON]:

The last question of Examination 1 is the hardest single item in VCE Specialist Mathematics. Its median full-mark rate across 2016–2025 is 18%. Concrete examples:

• 2018 Exam 1 Question 10 (5 marks) — a vector-calculus arc-length problem: the position vector r(t) = (t³/3)i + (arcsin(t) + t√(1 − t²))j with the distance travelled expressed as ∫₀^{3/4}√(at² + bt + c) dt. Mark distribution 35 / 22 / 24 / 17 / 0 / 2 — 2% of the state earned all five marks, and literally nobody scored exactly four [QJSON].
• 2023 Exam 1 Question 10d (2 marks) — 7% full marks, distribution 44 / 49 / 7.
• 2024 Exam 1 Question 3c (3 marks) — 10% full marks, distribution 51 / 13 / 25 / 10.

The planning implication is concrete. Roughly 5 of Examination 1's 40 marks are effectively reserved for the top few per cent. Everything before them is worth more per minute. A 45+ candidate should reach Q10 with time, not stumble into it.

6.6.6 The "separator zone", year by year

Marks on each paper for which fewer than 30% of the state earned full marks ([QJSON], November sittings):

2021 Examination 2 is the hardest paper in the archive — nearly half its marks were earned in full by fewer than three students in ten, and 22 marks by fewer than three in twenty. 2025 Examination 2 is the most accessible — only two of its marks fell below a 30% full-mark rate.

The volatility is the point. In a good year you may need 74/80 on Examination 2 to be in the top 2%; in a 2021-style year, 62/80 could do it. Because study scores are ranks, this volatility does not hurt you — but it means raw-mark targets copied from another year are meaningless.

6.6.7 The hardest individual questions in the modern archive

Written parts with the lowest full-mark rates, 2016–2025 [QJSON]:

2017 Exam 2 Question 4f deserves its own note as the hardest single mark ever set: "The equation of the line passing through the two roots of z² + 4z + 16 = 0 can be expressed as |z − a| = |z − b|, where a, b ∈ C. Find b in terms of a." One mark. 1% of the state got it [PAPERS], [QJSON].

Hardest multiple-choice items, 2016–2025 [QJSON]:

2017 Exam 2 Question 10 is the only item in the archive where the state's modal answer beat the correct answer seven-to-one. Under the five-option format a 6% correct rate is below random guessing.

6.7 Cohort size

VCAA, Satisfactory completion of VCE units (Section 2 statistics):

Satisfactory-completion rates at Units 3 and 4 run 99.4–99.7%.

The long view, from the examination reports [RPT]:

Specialist Mathematics shrank by roughly a third between 2005 and 2012, bottomed out in the mid-3,000s, and has grown 12.4% in the two years to 2025. A growing cohort at the entry margin tends to mean a slightly weaker median and a slightly more forgiving rank distribution — but only slightly, and it does not change the top 2% threshold materially.

6.8 Scaling

Specialist Mathematics is the most heavily up-scaled study in the VCE.

VTAC Scaling Report figures for Specialist Mathematics:

The 2025 adjustments are +9, +11, +13, +13, +11, +9, +5 at study scores of 20, 25, 30, 35, 40, 45, 50 respectively. The maximum, 55, is the VTAC ceiling — scaled scores run 0.00 to 55.00, so a raw 50 in Specialist Mathematics reaches the top of the scale.

Compared with the other mathematics studies (2025):

Specialist Mathematics had the highest scaled mean of any VCE study in 2023, 2024 and 2025. The next highest in 2025 was Algorithmics (HESS) at 37.3; Chemistry was 33.6.

VTAC's own explanation of the mechanism (ATAR and Scaling Guide 2026, "Scaling: keeping things fair"), verbatim:

"Scaling adjusts for the fact that it is more difficult to obtain a high VCE study score in some studies than others. This is not because some studies are inherently harder or easier, it is because some studies attract a more competitive cohort of students."

"When VTAC receives your study scores from the VCAA, each study has been standardised. The average score for each study is 30. VTAC looks at the assessment data across all studies to make sure obtaining the average score in one study required the same level of achievement as every other study. When the data demonstrates the overall level of scores across studies doesn't match, adjustments need to be made. This is the scaling process."

"If competition in a particular study was higher than the average level of competition across all studies—as indicated by the group of students performing higher in their other studies—study scores need to be adjusted upwards, otherwise students doing that study would be unfairly disadvantaged."

The mathematics-specific rule — this is the sentence that explains why Specialist sits so far above everything else, and it is very widely misquoted:

"VCE Mathematics studies are designed to cater for students of differing abilities and interests. Unlike other studies there is a distinct hierarchy of studies: Specialist Mathematics is the most difficult, followed by Mathematical Methods, followed by General Mathematics, and then Foundation Mathematics. To ensure that students undertaking the more difficult mathematics studies are not disadvantaged by the level of difficulty, all four mathematics studies are scaled against each other as well as being scaled against all other studies. The higher of the two resulting scales is used for each of the mathematics studies."

And VTAC's anti-gaming warning, verbatim:

"It is most likely that a 'scaled down' score in a study you performed well in will be higher than a 'scaled up' study in which you didn't."

In other words: taking Specialist Mathematics because it scales, and then performing poorly in it, is a losing trade. The scaling boost is real but it is applied to your rank, and your rank is set against the strongest mathematics cohort in the state.

Two caveats VTAC states explicitly.

1. The means and standard deviations above "pertain to the scaling population" — students with at least one study score that year, at least four study scores in total, at least one English study, and no existing ATAR. They are not the whole VCE cohort.
2. The integers in the table are "an indication". The real aggregation uses scaled scores to two decimal places.
3. The 2026 Scaling Report is not yet published (VTAC publishes in mid-December). Anyone quoting 2026 scaling numbers before then is guessing.

6.9 What a 45+ actually requires — assembling the evidence

Nothing below is a VCAA statement; it is inference from the evidence above, and is labelled as such.

1. Rank, not marks. A 45 is roughly the top 2% of ~4,000, i.e. approximately the 80th-ranked student in the state (§6.3, §6.7). There is no fixed raw score.
2. Both examinations, not one. GA2 and GA3 together are 60% of the study score, and the two examinations jointly set the moderation scale for the 40% coursework component (§6.2). Examination 2's 40% makes it the single dominant assessment.
3. Coursework is table stakes. ~57% of the state is at B+ or above on GA1 and ~35% at A or A+ (§6.5). An A+ on coursework does not distinguish you; anything less actively costs you.
4. The exam A+ bands are ~7.5% each (§6.5). Being in the top 2% overall realistically means A+ on both papers, which means roughly the top one-in-thirteen performance on each.
5. The separation happens on a small number of marks. In a typical recent paper, 6–14 of Examination 1's 40 marks and 12–25 of Examination 2's 80 marks are earned in full by fewer than 30% of the state (§6.6.6). Those 20–40 marks are where the top 2% is decided. Everything else is marks you are expected not to lose.
6. Three specific structural leaks, all avoidable: - the last question of Examination 1 (median 18% full marks — §6.6.5), which rewards arriving with time on the clock; - the (d) and (e) parts of Section B questions (median 46% and 39% — §6.6.4); - Section B Question 6, which is as accessible as Question 1 (median 60%) and is the most commonly sacrificed to poor time management (§6.6.4).
7. Multiple-choice is no longer free. The Section A mean has been below 60% in six of the last ten years, and the move to four options in 2024 has tightened distractor design (§3.4, §6.4). At 1 mark each with no penalty, every item must be attempted — but treat Section A as 20 real marks requiring 30 real minutes, not a warm-up.
8. Scaling rewards the decision to take the subject, not a poor result in it. A raw 45 scales to 54 and a raw 50 to 55 (§6.8), so the top of the scale is compressed: the marginal return on going from 45 to 50 is one scaled point, whereas going from 35 to 40 is worth three. For ATAR purposes, a 45 in Specialist is already close to the ceiling.
