GCSE Maths has clear right and wrong answers. Unlike essay subjects, there is no ambiguity — which means consistent practice with the right approach will produce real results.
Step 1: Know Your Tier and Your Gaps
GCSE Maths is sat at two tiers:
- Foundation tier (grades 1–5): number, fractions, percentages, ratio, basic algebra, data handling
- Higher tier (grades 4–9): all foundation topics plus surds, functions, circle theorems, vectors, proof
Download your exam board’s specification (AQA, Edexcel, or OCR) and go through every topic. Mark each one: confident, shaky, or no idea. This gap analysis is your revision plan.
Step 2: Use Active Recall, Not Passive Reading
Reading through notes or watching videos feels productive but produces weak results. Active recall — attempting to retrieve information before checking — is significantly more effective.
Practical application:
- Close your notes and attempt questions before checking answers
- Use flashcards for formulae not given in the exam
- Work through past paper questions topic by topic
- Re-attempt wrong questions from scratch a few days later
Step 3: Prioritise the High-Mark Topics
Some topics appear on every paper and carry large mark allocations:
- Algebra (solving equations, factorising, simultaneous equations) — all three papers
- Fractions, decimals, percentages — foundation of many other topics
- Ratio and proportion — high mark allocation across both tiers
- Graphs (linear, quadratic, real-life graphs) — Papers 1 and 2 staple
- Geometry (area, perimeter, volume, angles)
- Probability and statistics
- Trigonometry (Higher tier — SOHCAHTOA, sine and cosine rule)
Step 4: Practice Past Papers Under Timed Conditions
Past papers are the most accurate preparation available. Aim to complete them under real exam conditions:
- Timed at 1 hr 30 min per paper
- No notes open
- Both calculator and non-calculator papers practised
- Marked using the official mark scheme
Aim for at least three full sets of three papers (nine papers total) before the exam.
Step 5: Fix Mistakes Properly
After marking each paper, categorise every error:
- Careless mistake — read the question again next time, slow down on checking
- Method gap — you knew the topic but applied the wrong approach
- Content gap — you have not learned this topic yet
Content gaps require going back to notes or getting explanation from a tutor. Simply re-doing papers without addressing gaps produces diminishing returns.
Step 6: Know Your Formulae
Given in the exam:
- Quadratic formula
- Cosine rule and sine rule
- Volume of cone and sphere
Must memorise:
- Pythagoras’ theorem
- Area of a triangle (½ × base × height)
- Circumference and area of a circle
- SOH CAH TOA
- Density = mass ÷ volume; Speed = distance ÷ time
