Section A: Non-Technical and Basic Engineering Foundations
What Section A tests
Section A checks whether you can reason clearly about engineering as a profession, not whether you can solve a discipline-specific problem. Expect questions on professional ethics and codes of conduct, safety and environmental responsibility, engineering economics, communication and documentation, units and dimensional consistency, basic mathematics and statistics, and elementary physics and materials concepts. The examiner is looking for disciplined judgement applied to a realistic scenario.
Concepts to master
Know the hierarchy of hazard controls (eliminate, substitute, engineer out, administrate, then personal protective equipment) and be able to rank options. Understand the difference between accuracy and precision, between systematic and random error, and between mean, median and mode when outliers appear. Be fluent in SI prefixes and unit conversion, and in the idea that any equation must be dimensionally homogeneous. For economics, distinguish simple from compound interest, and capital cost from operating cost.
Traps that catch candidates
- Choosing the last control in the hierarchy (PPE) because it is the cheapest or quickest.
- Confusing precision (repeatability) with accuracy (closeness to truth).
- Mixing up units, for example treating kN and kg as interchangeable.
- Reading a scenario as a purely technical problem when the question asks about professional conduct, such as disclosing a conflict of interest or refusing to sign off unverified work.
- Answering what is legal rather than what the code of ethics requires.
Worked rule of thumb
For unit checks, carry the units through the arithmetic as if they were algebraic symbols. A force of 2 kN acting over 3 m gives 2 kN x 3 m = 6 kN·m, which is 6 kJ, not 6 J. If the resulting units do not match the quantity you were asked for, your formula is wrong before you have done any numbers.
For ethics scenarios, ask: who could be harmed, what would a reasonable professional do, and would I be comfortable defending this decision publicly?
