Exam tips
Paper format
- Duration
- 180 min
- Total marks
- 100
- Weighting
- 100%
- Question types
- STEM aptitude and engineering reasoning
- For forces, gears, pulleys, circuits, flow, and structures, draw inputs, outputs, constraints, and direction before calculating.
- A three-hour paper still punishes arithmetic drift. Estimate order of magnitude and unit before doing exact calculation.
- Engineering items often ask for the best design under constraints. Compare cost, strength, safety, efficiency, maintainability, and environmental impact.
Common mistakes
Mechanics
Writing equations before identifying forces, supports, and direction.
How to avoid: Draw a free-body or system diagram first.
Units
Mixing centimetres with metres or grams with kilograms.
How to avoid: Convert all quantities to SI units before substitution.
Engineering design
Choosing the strongest design when the question asks for lowest cost or easiest maintenance.
How to avoid: Circle the design criterion in the stem.
