Combined Science students still need strong biology notes — but the biology content is shared with chemistry and physics in one qualification. Cambridge schools usually enter 0653 (Combined Science) or 0654 (Co-ordinated Sciences Double Award) — check your statement of entry. Do not use full 0610 Biology depth for every topic unless your teacher confirms overlap.

Building a combined biology notebook

1. Split binder: Biology | Chemistry | Physics dividers.
2. One syllabus tick-list for biology sections only.
3. Use topic guides: cells, ecology, etc. — stop when syllabus ends.
4. Practise cross-topic questions (bio + chem) when they appear in school tests.

Common mistake

Downloading 0610 Extended notes when you sit 0654 — creates stress and irrelevant content. Filter by code.
