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
