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.
