Study Tips
- 1
Required practicals are worth marks in both papers — know the method, variables, and expected results for all 10.
- 2
Six-mark extended response questions require a structured answer: begin with a clear opening statement and use specific biological vocabulary throughout.
- 3
Homeostasis (thermoregulation, blood glucose control, kidney function) appears every year across both papers.
- 4
Learn every diagram in the textbook — heart, kidney nephron, cell, synapse, reflex arc — and be able to label them without looking.
Past Exam Questions
Describe the structure of DNA. Explain how semi-conservative replication ensures identical copies are produced during cell division. [6 marks]
Common Mistakes to Avoid
- ✕
Describing what happens instead of explaining why — extended questions grade the mechanism, not the observation.
- ✕
Using vague everyday language where precise scientific terminology is required.
- ✕
Ignoring units and significant figures in calculations.
