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.

QCE Year 12Specialist MathematicsComplex rootshardroot diagram
1. The diagram marks point P, the root of z4 = 16 with argument 3π/4. Which exact Cartesian form is P?
Choices
-√2 + √2i
√2 + √2i
-√2 - √2i
2 + √2i
Explanation:
Each root has modulus 161/4 = 2. At argument 3π/4, P = 2(cos 3π/4 + i sin 3π/4) = -√2 + √2i.

2. Points A(1, 2, 0) and B(4, -1, 2) define a line. Which vector equation represents the line AB?
Choices
r = (1, 2, 0) + λ(3, -3, 2)
r = (1, 2, 0) + λ(5, 1, 2)
r = (4, -1, 2) + λ(3, 3, -2)
r = (3, -3, 2) + λ(1, 2, 0)
Explanation:
The direction vector is AB = (4 - 1, -1 - 2, 2 - 0) = (3, -3, 2). A valid line equation is r = (1, 2, 0) + λ(3, -3, 2).

3. A particle has velocity v(t) = 3t2 - 12t + 5. What is the acceleration at t = 3?
Choices
6 m/s2
-6 m/s2
20 m/s2
0 m/s2
Explanation:
Acceleration is the derivative of velocity. Since v'(t) = 6t - 12, a(3) = 18 - 12 = 6 m/s2.
QCE Year 12Specialist MathematicsDifferential equationshardslope field
4. A model satisfies dy/dt = 0.4(10 - y), and the drawn solution starts below 10. Which long-term behaviour is consistent with the solution?
Choices
y increases towards 10
y decreases towards 0
y becomes negative
y grows without bound
Explanation:
The equilibrium is y = 10. When y < 10, dy/dt is positive, so the solution increases and approaches the stable equilibrium y = 10.
QCE Year 12Specialist MathematicsFurther integrationhardtangent and area graph
5. What is the exact value of the integral from 0 to π/2 of sin x cos x dx?
Choices
1/2
1
0
π/4
Explanation:
Use u = sin x, so du = cos x dx. The integral becomes ∫ from 0 to 1 of u du = 1/2.
QCE Year 12Specialist MathematicsProof and counterexamplehardtransformation graph
6. Which counterexample disproves the claim: if f'(0) = 0, then f has a local maximum at x = 0?
Choices
f(x) = x3
f(x) = -x2
f(x) = 1 - x2
f(x) = 4
Explanation:
For f(x) = x3, f'(x) = 3x2, so f'(0) = 0. But x = 0 is a stationary point of inflection, not a local maximum, so the claim is false.
For parents comparing QCE Year 12 Specialist Mathematics support
QCE Year 12 Specialist Mathematics practice should make complex numbers, vectors, proof, mechanics, and further calculus feel structured rather than guessable. These examples preview that style before the no-login Specialist Mathematics demo.

Specialist Mathematics practice sits inside QCE Mathematics Units 3 and 4 structures across supported pathways, 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.
