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 TASC Year 12 Essential Mathematics questions

These sample questions are visible on the page before login. They show TASC Year 12 Essential Mathematics finance, measurement, rates, data, probability, and practical modelling explanations before opening the demo.

TASC Year 12 Essential Mathematics Depreciation hard finance graph

1. A laptop worth $4200 depreciates by 18% p.a. on a reducing-balance basis. What is its value after 3 years, to the nearest cent?

Reducing-balance depreciation V₃ n $
Choices
  • $2,315.75
  • $3,444.00
  • $2,268.00
  • $2,904.77
Explanation:

Reducing-balance depreciation gives V = 4200(0.82)3 = 2315.7456, so the value is $2315.75 to the nearest cent.

TASC Year 12 Essential Mathematics Loans and recurrence hard finance graph

2. A loan balance follows Bₙ₊₁ = 1.006Bₙ - 420 with B₀ = 12000. What is B₂, to the nearest cent?

Loan balance after two repayments B₂ n $
Choices
  • $11,301.91
  • $11,652.00
  • $12,072.00
  • $10,812.00
Explanation:

B₁ = 1.006 x 12000 - 420 = 11652. Then B₂ = 1.006 x 11652 - 420 = 11301.912, so B₂ is $11,301.91.

TASC Year 12 Essential Mathematics Scale and cost hard scale plan

3. A car park is 6.8 cm by 4.5 cm on a 1:500 plan. Resurfacing costs $18 per square metre. What is the resurfacing cost?

Scale plan for resurfacing 6.8 4.5 1:500
Choices
  • $13,770
  • $1,377
  • $7650
  • $18,360
Explanation:

The actual dimensions are 34 m by 22.5 m, so the area is 765 m2. At $18 per square metre, the cost is 765 x 18 = $13,770.

TASC Year 12 Essential Mathematics Conditional probability hard probability tree

4. Machine A makes 55% of items with defect probability 0.04. Machine B makes 45% of items with defect probability 0.07. What is the probability a randomly selected item is defective?

Defect probability tree A D +
Choices
  • 0.0535
  • 0.1100
  • 0.0315
  • 0.0550
Explanation:

Add the defective branches: 0.55 x 0.04 + 0.45 x 0.07 = 0.022 + 0.0315 = 0.0535.

TASC Year 12 Essential Mathematics Networks hard network diagram

5. A minimum cable network uses selected edges with lengths 6 m, 8 m, 5 m, 9 m, and 7 m. What total cable length is needed?

Minimum cable network A F 35
Choices
  • 35 m
  • 30 m
  • 40 m
  • 45 m
Explanation:

A minimum spanning network connects all required points without a loop. Add the selected edge lengths: 6 + 8 + 5 + 9 + 7 = 35 m.

TASC Year 12 Essential Mathematics Utility modelling hard break-even graph

6. A water bill charges a fixed $83 plus $2.18 per kilolitre. A household uses 1.4 kL per day for 92 days. What is the total bill, to the nearest cent?

Linear utility cost model C B 128.8
Choices
  • $363.78
  • $280.78
  • $211.84
  • $446.78
Explanation:

The usage is 1.4 x 92 = 128.8 kL. The usage charge is 128.8 x $2.18 = $280.78 to the nearest cent. The total bill is $83 + $280.78 = $363.78.

For parents comparing TASC Year 12 Essential Mathematics support

TASC Year 12 Essential Mathematics practice should make finance, measurement, rates, data, probability, and practical modelling feel structured rather than guessable. These examples preview that style before the no-login Essential Mathematics demo.

What this practice and exercise page covers

Essential Mathematics practice sits inside TASC Year 12 mathematics planning coverage across essential, general, methods, specialist, algebra, calculus, statistics, probability, finance, and modelling topics, 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
  • Number and financial maths: Students practise number and financial maths through short targeted questions, explanations, and mode-specific feedback.
  • Measurement and practical geometry: Students practise measurement and practical geometry through short targeted questions, explanations, and mode-specific feedback.
  • Algebra and graphs: Students practise algebra and graphs through short targeted questions, explanations, and mode-specific feedback.
Suggested first practice steps
  • Preview the public sample practice and exercise 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.

These examples are not the full topic list. Use the curriculum coverage page for the complete mapped pathway.
