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 HSC Year 11 Mathematics Standard questions

These sample questions are visible on the page before login. They show HSC Year 11 Mathematics Standard finance, measurement, networks, data, probability, and trigonometry explanations before opening the demo.

HSC Year 11 Mathematics Standard Financial mathematics hard growth graph

1. Option A invests $8000 at 6% p.a. compounded monthly for 2 years. Option B pays 6.2% p.a. simple interest for 2 years. Which return is better, to the nearest cent?

Choices

Option A by $25.28
Option B by $25.28
Option A by $992.00
The returns are equal

Explanation:

Option A grows to $8000(1.005)²4 = $9017.28. Option B grows to $8000 + $8000 x 0.062 x 2 = $8992.00. Option A is higher by $25.28.

HSC Year 11 Mathematics Standard Scale and measurement hard scale plan

2. A floor plan uses a scale of 1:80. A study measures 7.5 cm by 4.2 cm on the plan. What is the actual area of the study?

Choices

20.16 m²
3.15 m²
31.5 m²
201.6 m²

Explanation:

At a scale of 1:80, 7.5 cm represents 6.0 m and 4.2 cm represents 3.36 m. The area is 6.0 x 3.36 = 20.16 m².

HSC Year 11 Mathematics Standard Networks hard network diagram

3. A minimum cable network uses selected edges with lengths 4 m, 5 m, 7 m, 8 m and 9 m. What total cable length is needed?

Choices

33 m
24 m
29 m
38 m

Explanation:

A minimum spanning network connects all vertices without a loop. Add the selected edge lengths: 4 + 5 + 7 + 8 + 9 = 33 m.

HSC Year 11 Mathematics Standard Data analysis hard regression graph

4. A regression model predicts water use with y = 18 + 1.6x, where x is the number of residents. For x = 12, actual water use is 42 kL. What is the residual, using actual - predicted?

Choices

4.8
-4.8
37.2
42

Explanation:

The predicted value is 18 + 1.6 x 12 = 37.2. The residual is actual - predicted, so 42 - 37.2 = 4.8.

HSC Year 11 Mathematics Standard Probability hard probability tree

5. A learner passes a theory test with probability 0.72. If they pass theory, P(pass practical) = 0.85. If they do not pass theory, P(pass practical) = 0.40. What is the probability they pass the practical test?

Choices

0.724
0.612
0.288
0.850

Explanation:

Use the two branches that end in passing the practical: 0.72 x 0.85 + 0.28 x 0.40 = 0.612 + 0.112 = 0.724.

HSC Year 11 Mathematics Standard Trigonometry and measurement hard diagram

6. A surveyor is 65 m horizontally from a tower. The angle of elevation to the top is 14°. What is the tower height, to the nearest 0.1 m?

Choices

16.2 m
15.7 m
63.0 m
267.8 m

Explanation:

Use tan(14°) = height / 65. The height is 65 x tan(14°) = 16.206..., which rounds to 16.2 m.

For parents comparing HSC Year 11 Mathematics Standard support

HSC Year 11 Mathematics Standard practice should make finance, measurement, networks, data, probability, and trigonometry feel structured rather than guessable. These examples preview that applied style before the no-login Mathematics Standard demo.

What this practice and exercise page covers

Mathematics Standard practice sits inside NSW Year 11 Preliminary Mathematics coverage across Standard, Advanced, Extension 1, functions, algebra, statistics, probability, finance, networks, and proof, 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

Data and statistics: Students practise data and statistics through short targeted questions, explanations, and mode-specific feedback.
Networks, matrices and modelling: Students practise networks, matrices and modelling through short targeted questions, explanations, and mode-specific feedback.
Financial mathematics: Students practise financial mathematics through short targeted questions, explanations, and mode-specific feedback.
