How to Revise GCSE Maths in 3 Months | Step-by-Step Guide
GCSE Maths can feel overwhelming, especially if exams are only 3 months away. But the truth is – with the right GCSE Maths revision plan, you can boost your grade quickly and effectively. Here’s our proven step-by-step approach.
Why 3 Months Is Enough to Revise GCSE Maths
When you first look at the entire GCSE Maths syllabus, it feels like an impossible task. But remember:
The exam is built around predictable question styles.
Topics repeat year after year, meaning you don’t need to master everything perfectly, just the areas that earn the most marks.
With consistent practice, even a short period like 12 weeks can be transformative.
Many students make the mistake of cramming in the final few weeks. In reality, what matters is structured, consistent study. Three months gives you time to cover weak topics, practise past papers, and refine exam technique.
Step 1: Identify Your Weak Topics
Before you start revising, you need to know exactly where you’re losing marks. Here’s how:
Complete a past paper under exam conditions (choose the same exam board you’ll sit; AQA, Edexcel, or OCR).
Mark it carefully using the official mark scheme.
Write down the specific topics where you dropped marks.
Common problem areas include:
Algebra (solving equations, simultaneous equations, factorisation)
Ratio and proportion
Geometry (angles, transformations, circle theorems)
Probability and statistics
Non-calculator arithmetic
This step is crucial. Without it, you’ll waste time revising topics you already know. A personalised GCSE Maths revision checklist helps you focus on what actually matters.
Step 2: Build a Weekly GCSE Maths Revision Schedule
Once you know your weak spots, you can build a focused plan. Here’s an example 12-week GCSE Maths revision plan:
Weeks 1–4: Strengthen foundations
Focus on number and algebra basics (fractions, percentages, equations). These appear in nearly every paper and are easy marks once mastered.Weeks 5–8: Tackle higher-level problem areas
Prioritise geometry, ratio, probability and applied maths. These carry heavy marks and often trip students up.Weeks 9–12: Exam conditions practice
At this stage, your goal is speed and accuracy. Complete 2–3 past papers per week, strictly timed, and mark them carefully.
Tip: Use a calendar and physically block out revision slots. Consistency is key , it’s better to do 30 minutes daily than cram 4 hours once a week
Step 3: Practice Like It’s the Real Exam
GCSE examiners reward method marks, meaning you can pick up points even if you don’t get the final answer. For example:
Writing the correct equation setup in an algebra problem
Showing clear steps in a ratio calculation
Drawing a labelled diagram in geometry
How to maximise method marks:
Always show your working, never just write the answer.
Write in full sentences when explaining reasoning.
Practise under timed conditions to build exam stamina.
By the final month, aim to complete two full past papers per week for Foundation tier and three per week for Higher tier.
Step 4: Use Proven GCSE Maths Revision Resources
You don’t need hundreds of resources, just the right ones:
Past Papers: Download directly from your exam board (AQA, Edexcel, OCR). They are the single most effective revision tool.
Examiner Reports: Available online - they show where students across the country lost marks last year.
Revision Cards: Flashcards for key formulas and rules.
Apps: Quizlet and Exam Solutions are great for quick practice.
Video Tutorials: YouTube channels like HegartyMaths and Primrose Kitten provide step-by-step worked examples.
Remember, it’s not about collecting resources, it’s about using them consistently.
Step 5: Get Expert Feedback
Even the best revision plan has limits if you’re working in isolation. Why? Because you don’t always spot your own mistakes.
That’s where a GCSE Maths tutor adds huge value. Tutors can:
Pinpoint why you’re consistently losing method marks.
Give examiner-style feedback on your past papers.
Adapt explanations to your learning style.
Keep you accountable and motivated.
At AK Education, our tutors specialise in fast improvement under exam pressure. Many students improve by 2 grades in just 12 weeks when supported properly.
Final Tip: Stay Consistent
Revising for GCSE Maths is like training for a marathon. You don’t sprint the night before; you build up stamina gradually.
Stick to your 12-week plan.
Track your scores across each paper, celebrate progress.
Stay positive. Even small improvements add up quickly.
Remember: It’s not about doing everything. It’s about doing the right things consistently.
