Top tips for Mathematics
- 1'Hence' = USE the previous result. Ignore it and lose marks.
- 2Solve trig over the FULL range — sin and cos give two solutions per 360° / 2π cycle.
- 3Always state which calculus rule (chain / product / quotient / by parts) you're applying.
- 4Exact values: surds (√3) and π fractions — examiners often want exact, not decimal.
- 5+ c on every indefinite integral. Always.
⚠️ Top mistakes examiners flag for Mathematics
- ✗Missing the second / third solution in trig equations.
- ✗Forgetting + c on indefinite integrals.
- ✗Working backwards in 'Show that' / 'Prove' questions.
- ✗Confusing < with ≤ — read the inequality carefully.
- ✗Using degrees when the question specifies radians (or vice versa).
✅ Phrases that earn marks
- → By the chain rule, …
- → Using integration by parts, …
- → Therefore the stationary point is a minimum (d²y/dx² > 0)
- → By the binomial theorem, the coefficient of x^r is…
- → Hence, using part (i), …
❌ Phrases that lose marks
- ✗ Working backwards from the printed answer

Cambridge International A Level Mathematics exam technique — FAQ
What are the most important command words in Cambridge International A Level Mathematics? ▼
Cambridge International A Level Mathematics (9709) papers use 6 core command words. The most frequently misread are Show that / Prove (where students add unnecessary explanation) and Explain (where students describe instead of reasoning with because/therefore). The full breakdown — what each word means, the answer structure, and the do/don't list — is in the interactive cheat sheet above.
What's the difference between "describe" and "explain" in Cambridge International A Level Mathematics? ▼
Describe asks WHAT happens — quote values from data, state the trend, no reasoning. Explain asks WHY — every sentence must contain "because", "therefore" or "as a result". Mixing them up is one of the highest-frequency reasons Cambridge International A Level Mathematics students lose marks they could have earned with the same content.
What are the top examiner-flagged mistakes for Cambridge International A Level Mathematics? ▼
Across recent Cambridge International A Level Mathematics examiner reports, the most-flagged mistakes are: Missing the second / third solution in trig equations.; Forgetting + c on indefinite integrals.; Working backwards in 'Show that' / 'Prove' questions.. The full list with explanations is in the "Top mistakes" block in the cheat sheet above.
