🔀 Board Differences

Board specifications differ in assessment structure and emphasis. The core content is shared across boards; these are the genuine differences by board:

AQA: Three papers, no multiple choice, and a unique 25-mark synoptic essay in Paper 3. Twelve prescribed required practicals with specific terminology in mark schemes.

Edexcel: Three papers with multiple choice and a pre-released scientific article for Paper 3 (examined in context, apply knowledge to the article). Context-led (Salters-Nuffield style). Sixteen core practicals.

OCR: Three papers; multiple choice on Papers 1 and 2 (15 marks each). No essays, shorter extended-response throughout. Practical work organised as twelve flexible PAGs.

WJEC: Welsh board, largely unitised into five units with an externally marked practical (Unit 5). Optional topics in Unit 4 (e.g. immunology, neurobiology).

CCEA: Northern Ireland's board; unitised structure with content broadly mirroring the other boards.
