- Learn what IB examiners reward — precise terminology and one point per mark
- Reduce exam anxiety through repeated realistic timed practice
Biology Exam Tips from Top Scorers
Make one point per mark
Count the marks and make that many separate, correct biological points. Examiners tick discrete marking points, so short and distinct beats one long sentence.
Use precise terminology
Write "active transport", "denatured", "semi-conservative replication" — the marking point usually needs the exact term, not a paraphrase of the idea.
Quote the data in Section B
Describe the trend, then lift specific figures with units off the graph or table before explaining the biology. A description with no numbers rarely earns the analysis mark.
Answer to the command term
"Outline" stays brief, "explain" needs reasons with "because", and "discuss"/"evaluate" need a balanced judgement. Match your answer to the verb.
