✍️ Sample N-LEVEL Questions & Answers

1. Which word is an antonym (opposite) of 'happy'?
✓ Sad

'Sad' is the opposite (antonym) of 'happy'. The other options (joyful, pleased, cheerful) are all synonyms of happy.

2. In food technology, what does 'food hygiene' include?
✓ Maintaining cleanliness of hands, tools, surfaces, and food itself to prevent contamination and foodborne illness

Food hygiene involves: washing hands, sanitising surfaces and utensils, proper food storage (correct temperatures), avoiding cross-contamination, and maintaining personal hygiene when handling food.

3. A train departs at 08:45 and arrives at 11:20. How long is the journey?
✓ 2 h 35 min

From 08:45 to 11:20: 11:20 - 08:45. From 08:45 to 09:00 = 15 min. From 09:00 to 11:20 = 2 h 20 min. Total = 2 h 35 min.

4. What is 'sustainable design'?
✓ Designing products that minimise environmental impact throughout their lifecycle — using renewable materials, reducing energy use, and enabling recycling

Sustainable design considers the environmental impact at every stage: material sourcing (renewable/recycled), manufacturing (low energy), use (efficient), and end-of-life (recyclable/biodegradable) — minimising ecological harm.

5. What is the area of a triangle with base 10 cm and height 6 cm?
✓ 30 cm²

Area of triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².

6. What does 'tolerance' mean in technical/engineering contexts?
✓ The permitted range of variation in a dimension — how much a measurement can differ from the nominal value

Tolerance in engineering is the acceptable range of variation in a measurement. For example, a bolt of 10mm ± 0.5mm means it can be 9.5mm to 10.5mm and still be acceptable.

What Practice Test Geeks adds beyond an AI chat for N-Level

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A fixed N-Level question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • A printable N-Level cheat sheet you can print or save as a PDF.
  • N-Level flashcards built from the same question bank.
  • Free N-Level practice tests with the correct answer shown after each question.
