Top tips for Mathematics A
- 1M marks: earnable with a wrong answer if working is shown.
- 2Geometric reasons: name the theorem ('alternate angles ARE EQUAL').
- 3Transformations: rotation = 3 things (angle, direction, centre). Enlargement = 2 things (SF, centre).
- 4'Show that': start from given, never from the printed answer.
- 5Accuracy: re-read for '3 s.f.', '2 d.p.' or 'exact form'.
⚠️ Top mistakes examiners flag for Mathematics A
- ✗'Z angles' instead of 'alternate angles are equal'.
- ✗Rounding mid-calculation.
- ✗Forgetting units squared on area or cubed on volume.
- ✗Confusing centre of rotation with centre of enlargement.
- ✗'3 s.f.' written to 2 d.p.
✅ Phrases that earn marks
- → Alternate angles are equal (parallel lines)
- → Angles on a straight line sum to 180°
- → By Pythagoras' theorem
- → Rotation 90° clockwise about (0, 0)
- → Enlargement scale factor 3, centre (2, 1)
❌ Phrases that lose marks
- ✗ Z angles
- ✗ Answer with no working
- ✗ Working backwards in proofs
- ✗ Forgetting units squared

What are the most important command words in Edexcel IGCSE Mathematics A? ▼
Edexcel IGCSE Mathematics A (4MA1) papers use 5 core command words. The most frequently misread are Show working (M marks) (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.
