How to revise for GCSE Maths: a practical plan

Maths is a subject you revise by doing, not by reading. This plan shows how to find weak spots, use past papers well and keep practice going until the exams.

Start with what you can already do

The most common revision mistake in maths is to go back over what feels comfortable. It feels productive, but it does not raise marks. Start instead by finding what needs work.

Take one full past paper under timed conditions, or use the most recent mock. Mark it honestly using the mark scheme. Then list every question where you lost marks, and sort them by topic: algebra, ratio, geometry, probability, number, statistics. That list is your revision plan.

Check your exam board and tier first. AQA, Pearson Edexcel, OCR and WJEC Eduqas all cover the same national content, but their papers have their own style and layout. Past papers from your own board are the best practice. You also need to know whether you are sitting foundation or higher, since the questions differ.

Build a simple weekly routine

Short, regular sessions beat one long weekend push. Aim for four or five sessions a week of 30 to 45 minutes. Maths takes concentration, and quality drops fast when you are tired.

  • Session 1 and 2: one weak topic each. Learn the method, then do 10 to 15 questions on it.
  • Session 3: mixed questions from topics you covered earlier in the term.
  • Session 4: part of a past paper, timed.
  • Session 5 (optional): go back over mistakes from earlier in the week.

Choose a fixed time for each session, so you do not need to decide each day whether to work. Put the phone in another room.

Use spaced practice

Spaced practice means returning to a topic several times with gaps in between, rather than doing it all at once. Memory fades, and each time you bring a method back you strengthen it.

A simple way to do this: after you revise a topic, come back to it a few days later with five questions, then again a week or two later with five more. If you can still do them, the method is secure. If not, it needs another look. You do not need a complicated system. A list in a notebook of topics with the dates you practised them is enough.

Mixing topics in a session also helps. In the exam, nobody tells you the question is about ratio. You have to spot it. Practice that switches between topics trains this skill.

Use past papers in the right order

Past papers are the best resource, but they are easy to waste. Doing a paper once and not looking at the mistakes gains very little.

  1. Early in revision, do individual questions by topic, with notes open.
  2. Mid-revision, do sections of papers with a timer, without notes.
  3. Closer to the exams, do full papers in exam conditions, including the non-calculator paper without a calculator.
  4. After every paper, mark it with the mark scheme and write down why each mark was lost.

Mark schemes show how marks are awarded for method, not just for the final answer. Learning to write out working clearly can win marks even when the answer is wrong.

Keep a mistakes notebook. For each lost mark, write the question topic, what went wrong (misread, wrong method, arithmetic slip, did not know) and the correct approach. Read it before every full paper.

Learn the kind of mistake you make

Not all lost marks are the same. A student who loses marks through careless slips needs a different fix from one who does not know the method.

  • Misreading: underline key words and numbers in the question before starting.
  • Arithmetic slips: check each line of working, and sense-check the answer. Is a percentage over 100? Is a length negative?
  • Not knowing the method: go back to the topic and learn it, then practise.
  • Running out of time: practise skipping a hard question and returning to it.

Things to learn by heart

Maths has fewer facts to memorise than other subjects, but a few do need to be known. Depending on your tier and board, you may be given some formulas in the exam and not others. Check which formulas your board provides, and learn the rest. Typical examples are the quadratic formula and the standard area, volume and circle formulas. Times tables and square numbers should be automatic, since they save time on every paper.

Use flashcards, or cover-and-recall sheets, for a few minutes at the start of a session. Mix them up so the order does not become the cue.

The weeks before the exam

In the last few weeks, shift towards full papers and exam habits. Practise showing every step of working, even in your head. Practise the calculator papers with the same calculator you will use on the day, and learn its functions, such as fractions, powers and brackets, so you do not lose time.

Look at the shape of the three papers. In most boards, one is non-calculator and two allow a calculator, and later questions on every paper are the hardest. Do not spend ten minutes on one question early on. Mark it, move on, and come back with the time left. Aim to finish with a few minutes spare to check answers.

Getting help when you are stuck

If one topic stays stuck after a few attempts, do not keep repeating the same questions. Ask your teacher, watch a different explanation, or work it through with someone who can see where your thinking goes wrong.

A one to one tutor can do this quickly because they watch you work and can see the exact step that breaks. If that would help, you can read about our GCSE maths tutors and how we match them to your exam board.
