How to Revise for Maths GCSE: A 6-Week Plan That Actually Works

Why Maths GCSE feels harder than it is

Most students fail to revise effectively for GCSE Maths not because the content is hard, but because they keep re-reading notes and watching videos instead of doing problems under pressure. Maths is a performance subject. You learn it the way you learn an instrument: short, focused practice every day, on the specific topics you're weakest at.

This guide gives you a 6-week plan you can start today.

Week 1: Diagnose, don't revise

Before you do anything, sit a full past paper under timed conditions. Pick the most recent one for your exam board (AQA, Edexcel, OCR). Mark it honestly.

You're not looking for a score. You're looking for the 3–5 topics where you lost the most marks. Write them down. These are your priority list.

Tip: Most students lose the same 20% of marks on the same 20% of topics. Find yours.

Week 2–3: Drill weak topics, 25 minutes a day

For each weak topic, do this loop:

Watch one short explainer (5 min) — Corbett Maths or Maths Genie are the gold standard.
Do 5 graded questions (15 min) — start easy, end at exam-level.
Mark and re-do anything you got wrong (5 min). Don't skip this.

Repeat every weekday. By the end of Week 3, your priority topics should feel boring — that's the goal.

Week 4: Mixed practice

Switch from topic drills to mixed papers. Do half a paper a day. The point is to practise choosing the right method when the topic isn't labelled for you.

Track every question you get wrong in a single notebook. By the end of Week 4 you'll see patterns — usually one or two algebra slips and a misread on geometry.

Week 5: Full past papers, timed

Three full papers this week, each under exam conditions. Mark with the official mark scheme. After every paper, ask:

Did I run out of time? → Practise pacing, not content.
Did I lose marks on working? → Slow down and show every step.
Did I blank on a topic? → Add it back to your priority list for one day.

Week 6: Exam-week routine

Two short sessions a day (45 min each), not one long one.
Re-do the questions you got wrong in Weeks 4–5, not new ones.
No new topics. No new past papers. Confidence > content.

The mistake that costs grades

Re-reading notes feels productive but it's the worst-value revision activity you can do. Active recall — getting questions wrong, then doing them right — is the only thing that moves your grade. Aim for 80% of your revision time to be questions, not notes.
