GCSE Biology revision

GCSE Biology revision for Year 10 and Year 11, across 5 official specifications from AQA, CCEA, Edexcel, OCR and WJEC. AQA GCSE Biology (8461) covers Cell biology (spec 4.1), Organisation (spec 4.2), Infection and response (spec 4.3), Bioenergetics (spec 4.4), Homeostasis and response (spec 4.5), Inheritance, variation and evolution (spec 4.6), Ecology (spec 4.7). Short interactive activities first, then a real past paper: the activities teach it, the paper tests it.

One thing the Biology questions here are written to catch: Xylem transport is driven by evaporation from the leaf rather than by gravity, so turning the leaf over does not reverse it.

Best next step

Start with Balance Basics. It takes about 7 minutes and needs no account.

Revise Balance Basics Then practise with GCSE Biology past papers

What you can revise here

Common questions

Is this page for Year 10 and Year 11?

Yes. It is built for Year 10 and Year 11 students revising GCSE Biology, and every topic on it is taken from the exam board's published specification rather than a generic syllabus.

Will it help with GCSE mocks?

Yes. This page lists 61 topics and 108 interactive modules, so you can revise the exact topic a mock covers, then sit a real past paper to check it under timed conditions.

Does it match AQA, CCEA, Edexcel, OCR and WJEC?

Yes. This page covers AQA, CCEA, Edexcel, OCR and WJEC, and each specification is listed separately with its own code, so you can pick the one your class follows.

Is it free to start?

Yes, and free all the way through: there is nothing to pay for any module. Making a free account is what saves your progress and streaks, though past papers download without one.
