GCSE Biology revision covers everything from the microscopic world of cells to whole ecosystems. Whether you're studying AQA, Edexcel, or OCR, you'll need to master topics like cell biology, organisation, infection and response, bioenergetics, homeostasis, inheritance, variation, ecology, and key practical skills.
The GCSE Biology exam is split across two papers. Paper 1 typically covers cell biology, organisation, infection, and bioenergetics. Paper 2 covers homeostasis, inheritance, variation, evolution, and ecology. Both papers include a mix of multiple-choice, short-answer, and extended-response questions worth 6 marks or more.
