What is a practice skill?

A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.

Sample ACT BSSS Year 12 Specialist Methods questions

These sample questions are visible on the page before login. They show ACT BSSS Year 12 Specialist Methods advanced functions, calculus, probability, regression, and inference explanations before opening the demo.

ACT BSSS Year 12 Specialist Methods Product and chain rule hard text

1. For f(x) = (x² + 1)e^x, what is f'(1)?

Choices

Explanation:

Using the product rule, f'(x) = 2xe^x + (x² + 1)e^x. At x = 1, f'(1) = 2e + 2e = 4e.

ACT BSSS Year 12 Specialist Methods Integral calculus hard text

2. What is the exact value of the integral from 0 to 1 of x / (x² + 1) dx?

Choices

(ln 2) / 2
ln 2
1 / 2
2 ln 2

Explanation:

Let u = x² + 1, so du = 2x dx. The integral is (1 / 2)ln(x² + 1) from 0 to 1, which is (ln 2) / 2.

ACT BSSS Year 12 Specialist Methods Discrete random variables hard text

3. A discrete random variable has P(X = 0) = 0.20, P(X = 1) = 0.35, P(X = 2) = 0.30, and P(X = 3) = 0.15. What is E(X)?

Choices

1.4
1.5
2.0
0.35

Explanation:

E(X) = 0 × 0.20 + 1 × 0.35 + 2 × 0.30 + 3 × 0.15 = 0.35 + 0.60 + 0.45 = 1.4.

ACT BSSS Year 12 Specialist Methods Normal distribution hard text

4. For X ~ N(72, 8²), use z = 1.04 for the 85th percentile. What is the approximate 85th percentile?

Choices

80.3
63.7
73.0
88.6

Explanation:

The percentile value is μ + zσ = 72 + 1.04 × 8 = 80.32, which rounds to 80.3.

ACT BSSS Year 12 Specialist Methods Regression hard text

5. A regression line is y = 5.2 + 0.74x. For x = 18, the observed value is 20.1. What is the residual, using observed - predicted?

Choices

1.58
-1.58
18.52
20.1

Explanation:

The predicted value is 5.2 + 0.74 × 18 = 18.52. The residual is 20.1 - 18.52 = 1.58.

ACT BSSS Year 12 Specialist Methods Statistical inference hard text

6. A sample has 84 successes in 120 trials. Using p̂ = 0.70 and z = 1.96, which interval is the approximate 95% confidence interval for the true proportion?

Choices

0.618 to 0.782
0.658 to 0.742
0.600 to 0.800
0.700 to 0.782

Explanation:

The standard error is √(0.70 × 0.30 / 120) = 0.0418. The margin is 1.96 × 0.0418 = 0.082, so the interval is 0.70 ± 0.082, or 0.618 to 0.782.

For parents comparing ACT BSSS Year 12 Specialist Methods support

ACT BSSS Year 12 Specialist Methods practice should make advanced functions, calculus, probability, regression, and inference feel structured rather than guessable. These examples preview that style before the no-login Specialist Methods demo.

What this practice and exercise page covers

Specialist Methods practice sits inside ACT BSSS Year 12 mathematics planning coverage across Essential Mathematics, Mathematical Applications, Mathematical Methods, Specialist Methods, Specialist Mathematics, algebra, calculus, statistics, probability, finance, and modelling, with Skill Align keeping the route focused on the selected maths pathway.

Senior practice is organised by pathway, unit, topic, and mode so students can revise targeted areas rather than sitting a full-paper workflow every time. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.

Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.

Preview question styles

Complex numbers and vectors: Students practise complex numbers and vectors through short targeted questions, explanations, and mode-specific feedback.
Proof, algebra and functions: Students practise proof, algebra and functions through short targeted questions, explanations, and mode-specific feedback.
Calculus and differential equations: Students practise calculus and differential equations through short targeted questions, explanations, and mode-specific feedback.
