Feeling overwhelmed by your upcoming GCSE Maths exams? You're not alone. Many students find maths revision challenging, but with a structured, strategic approach, you can build confidence and significantly improve your grade. This step-by-step guide is designed for UK students (Years 10-11) and teachers, breaking down the revision process into manageable, effective actions.
Step 1: Know Your Enemy – The Exam & Specification
Before you dive in, you need to know what you're revising. Your exam board (AQA, Edexcel, OCR, or Eduqas) publishes a detailed specification. This document lists every single topic you could be tested on. Download it from your exam board's website. Your teacher can help you find the right one.
Key Actions:
Identify your exam board and tier (Foundation or Higher).
Print the specification or save a digital copy.
Skim through it to understand the breadth of content: Number, Algebra, Ratio & Proportion, Geometry, Probability, and Statistics.
Step 2: Diagnose Your Strengths and Weaknesses
You can't fix what you don't know is broken. Start your revision by taking a diagnostic test. This could be:
A full past paper under timed conditions.
A topic test from your revision guide or school.
An online diagnostic quiz (e.g., on BBC Bitesize or MathsGenie).
Mark it rigorously. Use a traffic light system (Red/Amber/Green) to colour-code topics on your specification or a checklist.
Green: Confident – just needs maintenance.
Amber: Somewhat unsure – needs practice.
Red: Don't understand – needs learning from scratch.
This visual map becomes your personalised revision plan.
Step 3: Create a Realistic Revision Timetable
Cramming doesn't work for maths. Consistent, spaced practice is key. Use your traffic light list to build a timetable.
Timetable Tips:
Be specific: Don't write "do algebra." Write "practise solving simultaneous equations."
Mix it up: Slot a Red topic early in a session when you're fresh, followed by an Amber topic, and end with some Green topic questions for confidence.
Short bursts: Aim for 30-45 minute focused sessions with short breaks.
Schedule past papers: Block out full 1.5-hour sessions closer to the exam.

Step 4: Active Revision – Don't Just Read!
Passively reading a textbook is the least effective way to revise maths. Maths is a doing subject.
Effective Active Techniques:
Practice Questions, Practice Questions, Practice Questions: This is the golden rule. Use questions from:
Past papers and practice papers.
Your revision guide (CGP is a popular choice in UK schools).
Websites like Corbettmaths, MathsGenie, and Dr Frost Maths.
The "Look, Cover, Write, Check" Method for Formulae:
Look at the formula (e.g., area of a trapezium: A = ½(a+b)h).
Cover it up.
Write it down from memory.
Check it. Repeat until it's perfect.
Create Your Own Resources:
Flashcards: For key formulae, definitions (e.g., "what is a prime number?"), and step-by-step methods (e.g., "steps to factorise a quadratic"). Use our always-free GCSE revision flashcards by topic for Foundation and Higher to practise key ideas.
Poster/Summary Sheet: Condense a big topic (e.g., "angles rules") onto one A4 page with diagrams and examples.
Teach It: Explain a concept to a friend, family member, or even your pet! If you can teach it, you understand it.
Step 5: Master Past Papers (The Most Important Step)
Past papers are your most valuable resource. They show you the exam format, wording, and difficulty.
How to use them effectively:
