IGCSE Biology (0610)

Updated for the 2023-25 Syllabus

IGCSE Biology (0610) has many topics and chapters, making it a content-heavy subject. The major challenge while dealing with IGCSE Biology is the apt completion of paper 4 (extended); paper 4s tend to be extremely lengthy and cumbersome to tackle. But don’t get disheartened! Revising and solving many past papers within the time limit will surely boost your performance! Moreover, examiners for IGCSE Biology tend to be lenient towards awarding marks; usually, descriptive questions worth 3-5 marks tend to have 7-10 keywords that increase your probability of gaining a lot of marks.

To help you out with effective and fast IGCSE Biology revision, we have specially designed our notes to be easy to understand and digest. Look out for our special tips and fun facts that will cheer you up for the examination!!

We hope our notes will benefit you in your examinations and help you score an A*!
