The exam at a glance

2026 WACE Mathematics Methods ATAR exam

Monday 2 November 2026, 9.20 am. Two sections sat in one session. Section One (calculator-free): 5 minutes reading, 50 minutes working, 35 percent of the exam. Section Two (calculator-assumed): 10 minutes reading, 100 minutes working, 65 percent of the exam. The exam samples all of Units 3 and 4.

The structure comes from the examination design brief in the SCSA Year 12 syllabus, and the times and date from the SCSA 2026 timetable (SCSA's site blocks automated downloads, so we checked these details against search-indexed copies of the SCSA documents; confirm against the current syllabus on the SCSA website). The paper itself states the exact marks for each section, which vary a little from year to year. As a rule of thumb, both sections run at about one mark per minute.

What you can take in:

  • Section One: standard items only (pens, pencils, eraser, ruler, highlighters). No calculator and no notes. A formula sheet is provided.
  • Section Two: up to three approved calculators (the paper assumes CAS capability), drawing templates, and notes on two unfolded A4 sheets (both sides). A formula sheet is provided.

Your course score combines the moderated school mark and the standardised exam mark 50:50, so this one three-hour sitting weighs as much as your full year of tests and investigations.

What is examined

The exam samples the whole Year 12 course. On this site the content is organised into two deep dives:

  • Calculus deep dive: differentiation rules, exponential, logarithmic and trigonometric derivatives, curve sketching, optimisation, rates of change, antidifferentiation, the Fundamental Theorem, areas and kinematics.
  • Probability and statistics deep dive: discrete random variables, Bernoulli and binomial distributions, probability density functions, the normal distribution, the sample proportion and confidence intervals.

Calculus and statistics both appear in both sections. Do not assume statistics lives only in Section Two: a calculator-free question can ask you to find an unknown constant in a probability table, find E(X)E(X) for a small distribution, or use symmetry of the normal curve.

Section One: calculator-free (50 minutes)

Section One questions are written to be done by hand, so they avoid long calculations and heavy algebra. That tells you what to drill: clean differentiation and integration, exact values, log laws and simple probability arithmetic.

How to use the 5 minutes of reading time. Find the two or three questions you are most confident about and plan to do them first. Note any "hence" chains, where part (b) relies on part (a).

Section One style: "show that", then "hence"

(a) Show that ddx(xln⁡x)=ln⁡x+1\dfrac{d}{dx}\left(x\ln x\right) = \ln x + 1. (b) Hence evaluate ∫1eln⁡x dx\displaystyle\int_1^e \ln x \, dx.

(a) Use the product rule with u=xu = x and v=ln⁡xv = \ln x:

ddx(xln⁡x)=1⋅ln⁡x+x⋅1x=ln⁡x+1.\frac{d}{dx}(x\ln x) = 1 \cdot \ln x + x \cdot \frac{1}{x} = \ln x + 1.

A "show that" is only complete when the last line matches the target exactly.

(b) Integrate the result of (a): ∫(ln⁡x+1) dx=xln⁡x+c\displaystyle\int (\ln x + 1)\,dx = x\ln x + c, so

∫ln⁡x dx=xln⁡x−x+c.\int \ln x \, dx = x\ln x - x + c.

Then
∫1eln⁡x dx=[xln⁡x−x]1e=(e−e)−(0−1)=1.\int_1^e \ln x\,dx = \big[x\ln x - x\big]_1^e = (e - e) - (0 - 1) = 1.

"Hence" means you must use part (a). A correct answer from a memorised rule with no link to (a) can lose method marks.

Section One style: stationary points with justification

Find and classify the stationary points of y=x3−6x2+9x+1y = x^3 - 6x^2 + 9x + 1, and state the point of inflection.

y′=3x2−12x+9=3(x−1)(x−3)y' = 3x^2 - 12x + 9 = 3(x - 1)(x - 3), so stationary points occur at x=1x = 1 and x=3x = 3.

y(1)=1−6+9+1=5y(1) = 1 - 6 + 9 + 1 = 5 and y(3)=27−54+27+1=1y(3) = 27 - 54 + 27 + 1 = 1.

y′′=6x−12y'' = 6x - 12. At x=1x = 1, y′′=−6<0y'' = -6 < 0, so (1,5)(1, 5) is a local maximum. At x=3x = 3, y′′=6>0y'' = 6 > 0, so (3,1)(3, 1) is a local minimum.

y′′=0y'' = 0 at x=2x = 2 and y′′y'' changes sign there, so (2,3)(2, 3) is a point of inflection.

The classification marks come from the sign of y′′y'' (or a sign table for y′y'), not from the coordinates.

Section Two: calculator-assumed (100 minutes)

Section Two is two-thirds of the exam. The calculator does the arithmetic, but the marks are for setting the problem up and communicating it. Write the rule or distribution you are using, the values you substitute and the answer with units or context.

Section Two style: binomial model

A nursery finds that 85 percent of its seedlings survive transplanting. A customer plants 20 seedlings. Assume survivals are independent.

Let XX be the number that survive, so X∼Bin(20,0.85)X \sim \text{Bin}(20, 0.85).

  • P(X≥18)=P(X=18)+P(X=19)+P(X=20)≈0.2293+0.1368+0.0388=0.4049P(X \ge 18) = P(X = 18) + P(X = 19) + P(X = 20) \approx 0.2293 + 0.1368 + 0.0388 = 0.4049.
  • E(X)=np=20×0.85=17E(X) = np = 20 \times 0.85 = 17 seedlings.
  • Var(X)=np(1−p)=20×0.85×0.15=2.55\text{Var}(X) = np(1-p) = 20 \times 0.85 \times 0.15 = 2.55, so σ≈1.60\sigma \approx 1.60.

Writing "X∼Bin(20,0.85)X \sim \text{Bin}(20, 0.85)" is itself usually a mark: it shows you identified the model and its parameters.

Section Two style: confidence interval with interpretation

In a random sample of 400 Perth households, 88 have a home battery. Find an approximate 95 percent confidence interval for the population proportion and interpret it.

p^=88400=0.22\hat{p} = \dfrac{88}{400} = 0.22.

SE=0.22×0.78400≈0.02071\text{SE} = \sqrt{\dfrac{0.22 \times 0.78}{400}} \approx 0.02071, and the margin of error is 1.96×0.02071≈0.04061.96 \times 0.02071 \approx 0.0406.

The interval is 0.22±0.04060.22 \pm 0.0406, so approximately (0.179,0.261)(0.179, 0.261).

Interpretation: we are 95 percent confident that between about 17.9 and 26.1 percent of all Perth households have a home battery, in the sense that 95 percent of intervals built this way from repeated random samples would contain the true proportion.

Use your notes sheets well. Put on them what you cannot quickly rederive: the calculator menu paths for binomial and normal calculations, a template for interpreting a confidence interval, the margin of error formula rearranged for nn, and two or three model optimisation set-ups. Do not copy the formula sheet onto them.

Command words: what each one demands

SCSA writes questions using the key words in its published glossary. In Methods they translate like this:

Word What earns the marks
State / Write down The answer only. Little or no working needed.
Calculate / Evaluate A numerical answer with enough working to follow.
Determine / Find Any valid method, shown. On a calculator question, write the set-up you entered.
Show that Every step from the given to the target. The target itself earns nothing; the steps do.
Hence Use the previous result. Other methods may lose marks.
Justify / Explain A reason tied to mathematics: a sign of f′′f'', a value of a probability, a comparison with a threshold.
Sketch Correct shape plus labelled key features (intercepts, stationary points, asymptotes, endpoints).

The exam instructions also make clear that for questions worth more than two marks, valid working or justification is needed for full marks. A bare correct answer on a four-mark question can lose most of its marks.

Common mistakes that cost marks

The five most expensive errors
  1. No working on a calculator question. "0.405" alone is not enough when three marks are available. Write the distribution and the probability statement you evaluated.
  2. Missing the constant of integration, or dropping it when a condition such as f(0)=3f(0) = 3 was given to find it.
  3. Signed area confused with area. When a curve dips below the xx-axis, split the integral at the root and add absolute values.
  4. Misinterpreting a confidence interval. It is not "a 95 percent chance the sample proportion is in the interval". The sample proportion is always at the centre.
  5. Degrees and radians. Methods calculus is in radians. Check your calculator mode before Section Two begins.

A time plan for the day

  • Section One (50 minutes): first pass through everything you can do quickly (about 35 minutes), second pass on the harder parts, last 3 minutes checking signs and that every "show that" lands on its target.
  • Changeover: clear your head. Section One is gone; you cannot change it.
  • Section Two (100 minutes): use the 10 minutes of reading time to spot the long multi-part questions. Keep moving: if a part has cost you more than twice its marks in minutes, leave a gap and come back. Later parts often do not depend on earlier numerical answers, or you can carry forward an error and still earn method marks.

Five-week plan to 2 November

  1. Week of 28 September: Calculus foundations. Rework the calculus deep dive and do all the calculator-free differentiation and integration you can find, by hand, against the clock.
  2. Week of 5 October: Statistics foundations. Work through the statistics deep dive, then practise binomial and normal questions on your calculator until the menu paths are automatic.
  3. Week of 12 October: First full past paper from the SCSA past exams page under timed conditions. Mark it with the official marking key and list every lost mark by cause.
  4. Week of 19 October: Target the causes. Draft your two notes sheets. Second full paper.
  5. Week of 26 October: Third paper, then light revision. Finalise the notes sheets. Sleep.

For quick exam-style practice, use the calculus quiz and the statistics quiz, then open the WACE Mathematics Methods syllabus notes to fix anything that is shaky.
