KCSE BIOLOGY MASTER BANK (Form 1–4) Final-Week Revision Edition — November 2026 KCSE HOW TO USE THIS IN YOUR FINAL WEEK Same system as the Chemistry and Physics banks: organized by topic cluster, not by form, because KNEC blends forms freely (a Paper 1 question can pull ecology from Form 2 and genetics from Form 4 in one paper). Biology at KCSE rewards PRECISE language over vague description — "explain," "describe," and "state" are marked differently, and half of all Biology marks lost are from imprecise wording of an otherwise correct idea. Watch for this throughout. For each cluster: core facts, key terms/processes, worked examples (including genetics crosses and ecology calculations), and exam traps.
