Hi IGCSE Biology students

Complete revision notes for Cambridge IGCSE Biology 0610, free and open to anyone. One set of pages covers both tiers: anything only Extended candidates need (the syllabus’s Supplement) is marked EXTENDED. Biology is a visual subject, so every page is built around labelled diagrams, with objectives, explanations, a worked example and practice questions with answers. The questions are my own, written in the style of the current papers. — Mr. Suta

📜A note on past papers

None of the practice questions is copied from a Cambridge paper. Work through real past papers from your school as well; Cambridge says the 2026–2028 syllabus has no significant changes that affect teaching, and the 2029 subject content is identical, so papers from 2023 onwards all test what these notes cover.
