Top tips for Biology
- 1For EVERY explain question: use 'because', 'therefore', or 'as a result' in every sentence.
- 2Name organisms and structures precisely: 'haemoglobin' not 'red blood cells'; 'active site' not 'enzyme part'.
- 3For 6-mark questions: plan 6 distinct points before writing. Each must be a separate idea.
- 4Describe ≠ Explain. 'Rate increases' = describe. 'Rate increases because more enzyme–substrate collisions have energy ≥ activation energy' = explain.
- 5Diagrams: label with biological terms, not everyday words. Use a ruler and label lines that touch the structure.
- 6Always state the variable on the y-axis when describing graphs ('the rate of photosynthesis…', not 'it…').
⚠️ Top mistakes examiners flag for Biology
- ✗Using 'particles' instead of named molecules/ions (water molecules, oxygen molecules, Na⁺ ions).
- ✗Confusing diffusion with osmosis — osmosis is the movement of WATER from high to low water potential through a partially-permeable membrane.
- ✗Leaving 6-mark essay questions as one block — examiners can't see 6 distinct points and award fewer marks.
- ✗Writing 'enzymes are used up in the reaction' — they are catalysts and are not consumed.
✅ Phrases that earn marks
- → …because the active site changes shape
- → …ions are free to move
- → …partially-permeable membrane
- → …higher water potential to lower water potential
- → …as a result of osmosis
- → …chemoreceptors detect the pH change
- → …by active transport, against the concentration gradient
❌ Phrases that lose marks
- ✗ The enzyme stops working
- ✗ Things move across the membrane
- ✗ Blood carries oxygen (say: haemoglobin carries O₂ as oxyhaemoglobin)
- ✗ Vague: 'it', 'stuff', 'things'
- ✗ 'Enzymes are killed' (use: denatured)

Cambridge IGCSE Biology exam technique — FAQ
What are the most important command words in Cambridge IGCSE Biology? ▼
Cambridge IGCSE Biology (0610) papers use 8 core command words. The most frequently misread are State (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 Biology? ▼
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 Biology students lose marks they could have earned with the same content.
What are the top examiner-flagged mistakes for Cambridge IGCSE Biology? ▼
Across recent Cambridge IGCSE Biology examiner reports, the most-flagged mistakes are: Using 'particles' instead of named molecules/ions; Confusing diffusion with osmosis; Leaving 6-mark essay questions as one block. The full list with explanations is in the "Top mistakes" block in the cheat sheet above.
