What a Biology prep course should cover
- Cell biology → ecology per syllabus order (avoid skipping genetics)
- Command words — describe vs explain vs suggest
- Diagrams — heart, kidney, reflex arc, food webs
- Data questions — always use the figure in your answer
- ATP skills — planning investigations, controls, safety
Topic weighting (revision planning)
Prioritise areas that recur on Paper 2: enzymes, transport, infection & immunity, homeostasis, inheritance, ecology. Pair content revision with past-paper questions each week.
Singapore note
5090 results feed into L1R5 for many JC/poly routes—start timed papers early enough to improve weak topics, not only recall.
