IGCSE Biology Notes: Core vs Extended
Choosing the wrong tier of IGCSE biology notes is one of the most common revision mistakes: a student on Extended who only studies Core summaries will miss entire question styles on Paper 2 and Paper 4.

How to confirm your tier
| Source | What to look for |
|---|---|
| Statement of entry | Core (codes ending in specific paper set) vs Extended |
| Teacher | Final decision before exam series |
| Mock papers | Which paper numbers you sat |
If unsure, ask before buying revision guides.
What changes between Core and Extended notes
| Area | Core notes focus | Extended adds (examples — check your syllabus) |
|---|---|---|
| Depth | Shorter explanations | More application and “suggest” questions |
| Genetics | Basic inheritance | More complex crosses / terminology |
| Ecology | Food webs, pollution | More data interpretation |
| Physiology | Main organs | Extra detail on control systems |
Your school’s official syllabus document is the final word — not a blog table.
Note-taking strategy by tier
Core candidates: Master definitions, labelled diagrams, and standard calculations (magnification).
Extended candidates: Add comparison tables, data question practice, and 6-mark planning — 6-mark technique.
