How to Revise for GCSE Maths

To revise for GCSE maths, work full past papers under timed conditions, mark them against the official mark scheme, and log every topic where you drop marks. Start in mid-February of Year 11, around 13 weeks before Paper 1 on 14 May 2027.

Do about 2 to 3 hours of maths a week, rising to a 90-minute paper most days once study leave begins in May. The exam runs across three papers from 14 May to 14 June 2027, so revision has to hold through mid-June, not peak on one date. Drill your weakest topics first (algebra and trigonometry are the usual culprits). For 2026 you are given a formulae sheet in the exam, but more than 20 formulae are not on it, so build a one-page list of those and learn them.

How many hours of revision a day for GCSE maths?

Aim for 2 to 3 hours of GCSE maths a week from mid-February of Year 11, split as 20 to 30 minutes on four or five days plus one longer weekend session. Across all your GCSE subjects that adds up to roughly 1.5 to 2 hours a day during term, alongside school lessons. Once study leave starts in May and timetabled classes stop, raise the daily total to 4 to 5 hours and give maths one full 90-minute past paper plus 30 minutes to mark it. Beyond about 5 hours a day, recall falls once concentration fades, so three 50-minute blocks with breaks beat one unbroken sitting.

A sample GCSE maths revision week (Year 11, spring term)

Here is a concrete weekly plan that totals about 3.5 hours and is weighted toward exam-style practice rather than passive note-reading. Monday: 30 minutes on algebra (solving equations, rearranging formulae, expanding brackets), 10 exam questions. Tuesday: maths rest day, revise another subject. Wednesday: 30 minutes on number and ratio (percentages, compound interest, proportion), 10 questions. Thursday: rest day. Friday: 30 minutes on geometry and trigonometry (Pythagoras, SOHCAHTOA, angle rules), 10 questions. Saturday: a full 90-minute past paper under timed conditions, no calculator if you are practising for the non-calculator paper (Paper 1 on AQA and Edexcel, sat 14 May 2027; Paper 2 or 5 on OCR, sat 27 May 2027). Sunday: mark Saturday's paper against the official mark scheme and redo every question you lost marks on. From late April, swap the topic blocks for more full papers.

Use past papers and mark schemes the way examiners do

Past papers are the single highest-return GCSE maths revision activity, so aim to finish at least 6 to 8 full papers before 14 May. AQA, Edexcel and OCR all publish past papers and mark schemes free on their own websites, and you must use your own board's papers because question wording and layout differ between them. The habit that lifts grades is marking your own work line by line: GCSE maths mark schemes award method marks and accuracy marks separately, so you can still bank marks for correct working even when the final answer is wrong. Reading the mark scheme shows you exactly how to lay out working to earn those method marks.

Use the formula sheet, but know its limits

For 2025, 2026 and 2027, GCSE maths exams provide a formulae sheet as an insert with every paper, so you are not expected to memorise every formula. The 2026 sheet, unchanged from 2025, gives you the circumference and area of a circle, Pythagoras' theorem, the trigonometric ratios, the area of a trapezium, the quadratic formula, and the sine and cosine rules, with extra probability formulae on Higher tier. It does not cover everything, though: more than 20 formulae are not on the sheet, so download your exam board's official sheet, write a one-page list of every formula it leaves out, and test yourself on those until recall is automatic. Knowing where each formula sits on the sheet also saves time under exam pressure.

Target the topics that carry the most marks

Algebra and number together carry the largest share of GCSE maths marks, so prioritise them when time is short. On the Higher tier, algebra is the heaviest single area, followed by ratio and proportion, then geometry and measures, with statistics and probability making up the remainder. The Foundation tier weights number more heavily and caps at grade 5, while Higher covers grades 4 to 9. Identify your weak topics from marked past papers, then spend the most time on the high-mark topics you currently get wrong rather than re-revising the ones you already secure.

When should you start revising for GCSE maths?

Start structured GCSE maths revision in mid-February of Year 11, about 13 weeks before Paper 1 on 14 May 2027, with light weekly review from the start of Year 11 in September. The exam is three papers spread across a month (Paper 1 on 14 May, Paper 2 on 27 May, Paper 3 on 14 June 2027), so steady topic coverage across a term beats cramming for a single date. Build the timetable backwards from those dates: list the topics, divide them across the weeks, and keep the last two to three weeks for full timed papers only. A tutor can map this plan to your exam board and your specific weak topics in the first session.

GCSE maths revision: common questions

How do you revise for GCSE maths effectively?
Effective GCSE maths revision is active, not passive: do questions rather than re-read notes. Work full past papers under timed conditions, mark them against the official mark scheme to see where method marks are lost, and keep a running list of weak topics to re-drill. Aim for 6 to 8 complete papers before Paper 1 on 14 May 2027, focusing your time on the high-mark topics (algebra, number, ratio) you currently get wrong.
How do I make a GCSE revision timetable?
Build it backwards from your exam dates. List every topic on your spec, divide them across the weeks between now and the exam, and block 20 to 30 minute sessions on four or five days a week per subject. Add one longer weekend slot for a full timed past paper and a separate slot to mark it. Keep the final two to three weeks for full papers only, and rebalance toward your weakest topics as marked papers reveal them.
When should I start revising for GCSEs?
Start structured revision in mid-February of Year 11, about 13 weeks before the first summer papers, with light weekly review from September of Year 11. For GCSE maths that means roughly 13 weeks before Paper 1 on 14 May 2027. Starting much later leaves too little time to cover every topic and sit enough past papers, and the three-paper format (14 May, 27 May, 14 June 2027) rewards steady coverage across a term over last-minute cramming.
How many hours of revision a day should I do for GCSE?
During term, about 1.5 to 2 hours a day across all subjects is realistic, which works out to roughly 2 to 3 hours a week on maths alone. During May and June study leave, when school lessons stop, raise the daily total to 4 to 5 hours. More than 5 hours a day tends to backfire because recall falls once focus drops, so short blocks with breaks beat one long sitting.
How many past papers should I do for GCSE maths?
Aim for at least 6 to 8 full past papers before the exam, using your own board (AQA, Edexcel or OCR). Sit each one under timed conditions, with no calculator on the non-calculator paper (Paper 1 on AQA and Edexcel, Paper 2 or 5 on OCR), then mark it yourself against the official mark scheme. The marking step matters as much as the paper: it shows you exactly how method and accuracy marks are awarded so you can lay out working to bank them even when the final answer is wrong.
What grade is a pass in GCSE maths?
GCSE maths is graded 9 to 1, with 9 the highest, replacing the old A* to G scale. A grade 4 is a standard pass and maps roughly to an old grade C; a grade 5 is a strong pass. Many sixth forms and colleges ask for at least a grade 4 or 5 in maths, and students who miss a 4 usually resit. The Foundation tier caps at grade 5, while the Higher tier covers grades 4 to 9.
