About Engineering Science examination preparation

Engineering Science combines physics principles with engineering applications. The examination covers mechanics, thermodynamics, electricity, and materials science at the relevant N-level.

How to use this resource for revision

A TVET past examination paper is most useful when it is treated as an active revision exercise. Try the questions yourself before checking the corresponding memorandum. Where you make an error, identify the reason — was it a knowledge gap, a calculation mistake, an interpretation issue, or an examination technique problem?

For stronger examination practice, complete the paper without unnecessary interruptions and keep track of the questions that take the most time. Afterwards, review the memorandum and separate knowledge gaps from mistakes caused by interpretation, calculation, structure, or examination technique.

applying physics principles

selecting appropriate formulae

performing calculations with units

interpreting engineering scenarios

explaining scientific reasoning

A practical revision approach

Create a formula sheet organised by topic. The memorandum rewards correct formula identification, proper substitution, and accurate unit handling — always write the formula before substituting values.
