GCSE Maths Revision Tips That Actually Work
GCSE maths revision tips: how to plan, which topics to start with, how to use past papers, and how to revise for the non-calculator paper.
The best GCSE maths revision tips come down to one idea: revise by doing questions, not by reading notes. Plan around the topics you find hardest, practise under timed conditions with past papers, and check every mistake until you understand it.
Know the exam you are revising for
Exam boards set their papers differently, so check your board’s specification. As an example, AQA GCSE Maths is three papers of 1 hour 30 minutes, each worth 80 marks: Paper 1 is non-calculator, and Papers 2 and 3 allow a calculator. Any topic can appear on any paper. You sit either Foundation tier (grades 1–5) or Higher tier (grades 4–9), and all three papers must be at the same tier.
Knowing this shapes your revision: you need to be confident without a calculator, and you can’t skip a topic because it “came up last time”.
Step 1: find your gaps
Start with a full past paper, timed, before you plan anything else. Mark it and list every topic where you lost marks. That list is your revision plan — not the topics you already enjoy.
Group what you find:
- Can’t start it: you need to relearn the topic.
- Started but went wrong: you need practice and a look at common mistakes.
- Careless slips: you need to check your work more carefully.
Step 2: make a realistic plan
- Spread revision over weeks, not the night before. Short, regular sessions beat long cramming sessions.
- Mix topics in each session (algebra, then geometry, then statistics) rather than doing one topic for hours. Mixing is harder, but it is what the exam does.
- Come back to each weak topic a few days later to make sure it stuck.
Step 3: revise by doing questions
Reading notes feels productive but builds little. For each topic:
- Read a short explanation — for example a lesson in the Learning Center.
- Work a few questions without looking at the answers.
- Check, then redo any you got wrong without help.
The practice questions give a new problem every time, with hints and worked solutions, so you can keep going until a topic feels easy.
How to revise for the non-calculator paper
Non-calculator questions test whether you can handle numbers fluently. Practise:
- Times tables to 12 × 12 and quick multiplication: .
- Fractions: .
- Percentages from 10% and 1%: 15% of 240 is .
- Long multiplication and division, and decimals: .
Use past papers properly
- Do them under exam timing, in one sitting, with nothing you wouldn’t have in the exam.
- Mark them with the mark scheme — see where method marks are given. Showing working earns marks even when the final answer is wrong.
- Keep a “mistakes list” and review it each week.
Learn the formulas you need
Check which formulas your board gives you on the paper and which you must memorise. A short list you test yourself on regularly works better than reading a long sheet. The algebra formulas cheat sheet and geometry formulas cheat sheet are good places to start.
Exam technique
- Read every question twice and underline what it asks for.
- Show your working — it earns method marks.
- Check the number of marks: a 4-mark question needs more than one line.
- Leave time to check: substitute answers back into equations, and estimate to see if answers are sensible.
- Don’t leave blanks; a correct first step can still earn a mark.
In the last week
Don’t start new topics. Redo questions from your mistakes list, do one more timed paper, and sleep properly — tiredness costs more marks than one extra evening of revision gains.
A sample revision week
- Monday: algebra — expanding, factorising and solving equations. Ten questions, then check.
- Tuesday: number without a calculator — fractions, percentages, ratio.
- Wednesday: geometry — angles, area, volume and Pythagoras.
- Thursday: statistics and probability.
- Friday: your mistakes list — redo every question you got wrong this week.
- Weekend: one timed past paper, marked with the mark scheme.
Adjust the topics to your own gaps; the pattern of short daily sessions plus one timed paper is what matters.
A worked non-calculator example: ratio
Share 84 in the ratio 3 : 4.
- Add the parts: parts.
- One part is .
- So the shares are and .
- Check: , and simplifies to .
Ratio questions like this appear in many forms, so practise them until the “find one part first” step is automatic.
Topics worth extra practice
These topics are worth extra time because they underpin so many questions:
- Fractions, decimals and percentages, and converting between them.
- Ratio and proportion.
- Rearranging formulas and solving equations, including with brackets.
- Angle facts and area and volume formulas.
- Probability, including tree diagrams.
Short lessons on percentages, equations and the Pythagorean theorem cover several of these with checked examples.
Foundation or Higher?
Your teacher usually decides the tier with you, based on your recent work. If you are near the boundary, focus on making the grade 4–5 topics secure first — they appear on both tiers.
Frequently asked questions
How do I revise for GCSE maths? Find your weak topics with a timed past paper, revise them by doing questions, check every mistake, and repeat with more past papers.
How many hours should I revise maths for GCSE? There is no single number; regular short sessions over several weeks work better than long last-minute ones. Focus on progress on your weak topics, not on hours.
Can I use a calculator in every GCSE maths paper? No. With AQA, for example, Paper 1 is non-calculator and Papers 2 and 3 allow a calculator. Check your exam board’s specification.
