Revision is not just rereading notes. Learn how to recall knowledge, practise applying it and use mistakes to improve before mocks and final examinations.

What revision really is
Rereading can feel productive without proving you can recall the material. Try answering without notes, checking carefully, applying the knowledge and revisiting it later.
A simple route from revision to exam practice
Choose the numbered topics for your OCR or AQA specification, then attempt an original 14-mark mini-mock and review any weaker areas.
Try a timed mini-mock
Use realistic question styles and self-marking.
Start with how to revise
Effective revision involves returning to a topic, attempting to remember it without prompts, testing your understanding and correcting mistakes. Start here if you are unsure how to revise, or if your revision currently consists of reading or highlighting notes.
