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 12 Mathematics Standard questions

These sample questions are visible on the page before login. They show HSC Year 12 Mathematics Standard finance, networks, measurement, statistics, and probability explanations before opening the demo.

HSC Year 12 Mathematics Standard Financial mathematics hard payslip diagram

1. A taxable income is $78,000. Tax is $5092 plus 32.5c for each dollar over $45,000, and the Medicare levy is 2% of taxable income. What is the total tax plus Medicare levy?

Tax table and Medicare levy T L Total
Choices
  • $17,377
  • $15,817
  • $16,652
  • $18,937
Explanation:

Tax is $5092 + 0.325 x ($78,000 - $45,000) = $15,817. The Medicare levy is 0.02 x $78,000 = $1560. The total is $15,817 + $1560 = $17,377.

HSC Year 12 Mathematics Standard Depreciation hard finance graph

2. A car worth $24,000 depreciates by 18% p.a. using the declining-balance method. What is the depreciation during the third year, to the nearest cent?

Declining-balance depreciation B₃ n $
Choices
  • $2,904.77
  • $4,320.00
  • $3,197.09
  • $16,137.60
Explanation:

At the start of the third year, the value is $24,000 x 0.822 = $16,137.60. The third-year depreciation is 18% of this: 0.18 x $16,137.60 = $2,904.77.

HSC Year 12 Mathematics Standard Networks hard network diagram

3. In the network, the shortest route from A to F uses A-C-D-F. If the edge weights on that route are 8, 6 and 7, what is the shortest distance?

Shortest route through a transport network A F 21
Choices
  • 21
  • 19
  • 22
  • 27
Explanation:

Add the weights on the stated shortest route: 8 + 6 + 7 = 21. The other displayed routes are longer, so the shortest distance is 21.

HSC Year 12 Mathematics Standard Measurement hard measurement diagram

4. A storage tank is modelled as a rectangular prism 2.4 m by 1.5 m by 0.8 m. How many litres does it hold when full?

Rectangular prism storage tank L W H
Choices
  • 2880 L
  • 288 L
  • 28.8 L
  • 4800 L
Explanation:

The volume is 2.4 x 1.5 x 0.8 = 2.88 m3. Since 1 m3 = 1000 L, the full tank holds 2880 L.

HSC Year 12 Mathematics Standard Statistics hard normal curve

5. A test score is modelled with mean 72 and standard deviation 8. What is the z-score for a mark of 86?

Standardised score on a normal curve A B μ
Choices
  • 1.75
  • 1.25
  • 0.57
  • 14
Explanation:

Use z = (x - μ)/σ. Here z = (86 - 72)/8 = 14/8 = 1.75.

HSC Year 12 Mathematics Standard Probability hard probability tree

6. A component is faulty with probability 0.04. A test detects a faulty component with probability 0.90 and gives a false positive on a working component with probability 0.06. What is P(test positive)?

Fault-test probability tree F P +
Choices
  • 0.0936
  • 0.0360
  • 0.0576
  • 0.9000
Explanation:

Use the two branches that end in a positive test: 0.04 x 0.90 + 0.96 x 0.06 = 0.036 + 0.0576 = 0.0936.

For parents comparing HSC Year 12 Mathematics Standard support

HSC Year 12 Mathematics Standard practice should connect syllabus skills to tax, depreciation, routes, measurement, statistics, and conditional probability. These examples preview that applied reasoning before the no-login Mathematics Standard demo.

What this practice page covers

Mathematics Standard practice sits inside NSW Year 12 HSC Mathematics course structures, with Year 11 Preliminary context available through the full curriculum coverage, 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.

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.
Suggested first practice steps
  • Preview the public sample questions before creating a saved student session.
  • Choose one focus area that has already been introduced at school.
  • Use exercise mode for immediate explanations, then test mode when the student is ready for delayed feedback.
