Top tips for Additional Mathematics

  1. 1Solve trig equations across the FULL range — check the question for radians vs degrees.
  2. 2Always state the rule (chain/product/quotient) in calculus questions.
  3. 3Show every step in 'prove identity' — one side at a time, never both.
  4. 4Exact values: use surds (√3, π/3) when the question expects them.
  5. 5For binomial expansion: list a_r explicitly before substituting.

⚠️ Top mistakes examiners flag for Additional Mathematics

  • ✗Missing solutions in trig equations (forgetting the second quadrant root, etc.).
  • ✗Manipulating both sides of an identity simultaneously — work ONE side at a time.
  • ✗Using decimals when exact (surd / π) answers are required.
  • ✗Forgetting +c on indefinite integrals.
  • ✗Stopping after finding the stationary x-value without finding y or testing nature.

✅ Phrases that earn marks

  • → By the chain rule, …
  • → Using sin²x + cos²x ≡ 1, …
  • → Therefore the stationary point is a minimum (since d²y/dx² > 0)
  • → In the range 0° ≤ x ≤ 360°, the solutions are …
  • → By inspection, x = …

❌ Phrases that lose marks

  • ✗ Working backwards from the answer
  • ✗ Solving 'both sides' of an identity simultaneously
  • ✗ Forgetting + c on indefinite integrals
  • ✗ Rounding mid-calculation

Cambridge IGCSE Additional Mathematics exam technique — FAQ

What are the most important command words in Cambridge IGCSE Additional Mathematics? ▼

Cambridge IGCSE Additional Mathematics (0606) papers use 5 core command words. The most frequently misread are Show that (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 IGCSE Additional 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 IGCSE Additional Mathematics students lose marks they could have earned with the same content.

What are the top examiner-flagged mistakes for Cambridge IGCSE Additional Mathematics? ▼

Across recent Cambridge IGCSE Additional Mathematics examiner reports, the most-flagged mistakes are: Missing solutions in trig equations; Manipulating both sides of an identity simultaneously; Using decimals when exact. The full list with explanations is in the "Top mistakes" block in the cheat sheet above.
