Key examiner messages
Top priorities from the principal examiner before you revise
The May/June 2025 Cambridge International AS & A Level Mathematics papers present a balanced yet rigorous assessment across all core components.
Maintaining a solid baseline of standard procedural tests, the examiners have cleverly integrated non-routine elements that separate the top candidates.
Overall, the papers represent a standard-to-challenging difficulty curve, requiring not only absolute accuracy but also profound conceptual flexibility.

Examiner notes & key calculations
- Radian Mode Neglect: Many candidates threw away straightforward marks in Pure 2 and Pure 3 by performing iterations or calculations involving trigonometric functions (such as secx\sec xsecx or cos πx\text{cos } \pi xcos πx) in degree mode instead of radian mode.
- Underestimating Domain Constraints: In Paper 11 (Functions), proving why a composite function cannot be formed relies heavily on checking whether the range of the inner function lies within the domain of the outer function. Vague statements like "the domains do not match" were heavily penalized.
- Hypothesis Testing Notation: A recurring pitfall in Paper 61 was the incorrect expression of null and alternative hypotheses using sample statistics (like xˉ\bar{x}xˉ) rather than population parameters (μ\muμ).
