Key examiner messages
Top priorities from the principal examiner before you revise
The May/June 2023 sitting for Cambridge AS & A Level Mathematics (9709) presented a balanced yet highly rigorous set of papers.
Paper 11 (Pure 1) and Paper 21 (Pure 2) both tested core algebraic proficiency, geometric intuition, and precise calculus execution.
While standard procedural questions (such as binomial expansions and polynomial division) offered accessible marks, multi-step problem-solving questions—particularly those involving rates of change, volume of revolution with coordinate boundaries, and trigonometric R-formula optimization—pushed candidates to their limits.
Therefore, the papers are rated as a solid 4 out of 5 stars in difficulty.
