Revision that works
How do I revise for GCSE maths?
Revise GCSE maths by doing questions, not reading notes. Work topic by topic: try questions, check your working against a full solution, and spend your time where you drop marks. Short, regular sessions beat long weekend catch-ups, and past papers in the final weeks tie it all together.

Why maths revision is different
Maths is a doing subject. Re-reading notes or copying out formulae feels productive, but your brain files it under "seen before" rather than "can do". The only reliable way to know whether you can answer a question is to answer one - without the notes open.
That is good news, because it makes maths one of the most improvable subjects on your timetable. Every question you attempt either confirms a skill or shows you exactly what to work on next. There is no guesswork about whether the revision is working.
The method: question, working, feedback
Pick one topic at a time and work through questions at your level, checking each answer against a full worked solution - not just the final number. Most marks in GCSE maths are for method, so the working is where marks are won and lost.
When a question beats you, that is the useful moment: read the solution step by step, then try a similar question fresh. If it beats you twice, that topic goes to the top of tomorrow's list. Weak topics should get most of your time - it feels nicer to practise what you're good at, but the marks live in the gaps.
A week that adds up
Little and often wins. Four or five short sessions of 25–40 minutes across a week beat one long Sunday session, because spacing forces your memory to retrieve, and retrieval is what makes it stick.
- Each session: one topic, questions first, notes only to un-stick yourself.
- Start each session with two or three quick questions from earlier topics - spaced review for free.
- Keep a running list of topics that beat you, and clear it before moving on to new ground.
- From about six weeks out, add one timed past paper a week and mark it honestly with the mark scheme.
When a topic just will not click
Go one level down, not one level up. If quadratic equations make no sense, the gap is often in the algebra underneath them. Find the easier skill inside the hard one, get comfortable there, then climb back. This is normal - it is how maths is built - and it is quicker than staring at questions that are two steps ahead of you.
