The Truth About IGCSE Revision: Most Students Do It Wrong

Here’s a statistic that might surprise you: research consistently shows that the most popular study methods — re-reading notes, highlighting textbooks, and copying out information — are among the least effective ways to learn. Students spend hours “studying” this way and wonder why their grades don’t improve.

If you’re preparing for IGCSE exams, this guide will show you what actually works — evidence-based study strategies that top-performing students use to consistently achieve A* and A grades. Whether you’re 6 months out or 6 weeks from your exams, these techniques will transform your revision.

The Science of Effective Studying

Before diving into specific strategies, let’s understand why some methods work and others don’t.

Why Re-Reading Doesn’t Work

When you re-read your notes, your brain recognises the information and creates a false sense of familiarity. You feel like you know it — but recognition is not the same as recall. In an exam, you need to recall information from scratch, not recognise it when you see it.

The Two Techniques That Actually Work

Decades of cognitive science research point to two techniques that dramatically outperform all others:

1. Active Recall — Testing yourself on material rather than passively reviewing it 2. Spaced Repetition — Spreading your practice over time rather than cramming

Everything in this guide builds on these two principles.

Building Your IGCSE Study System

Step 1: Audit Your Syllabus

Before studying anything, you need a map. For each IGCSE subject:

1. Download the syllabus from Cambridge or Edexcel’s website
2. Print or create a checklist of every topic
3. Traffic light each topic:
   • 🟢 Green = confident, can explain it to someone else
   • 🟡 Amber = understand the basics but shaky on details
   • 🔴 Red = don’t understand or haven’t covered yet

This gives you an honest picture of where you stand and where to focus your energy.

Step 2: Gather Your Resources

For each subject, you need:

• Your class notes (organised by topic)
• The textbook (for reference and practice questions)
• Past papers (minimum 5 years — download from your exam board’s website)
• Mark schemes (just as important as the papers themselves)
• Examiner reports (reveal what examiners are looking for)
• Summary/revision notes (create your own — see below)

Step 3: Create Active Revision Materials

Flashcards (for knowledge-based content):

• One question per card
• Keep answers concise
• Include diagrams where relevant
• Use apps like Anki or Quizlet for digital flashcards with spaced repetition built in

Summary sheets (for each topic):

• Condense each topic onto one page
• Use diagrams, flowcharts, and tables
• Write in your own words (not copied from the textbook)
• The process of creating these is where much of the learning happens

Mind maps (for connecting ideas):

• Great for subjects like Biology, Geography, and History
• Show relationships between concepts
• Use colour coding for different themes
• Review and recreate from memory

The Five Most Effective IGCSE Study Techniques

Technique 1: Past Paper Practice (The #1 Strategy)

If you do nothing else on this list, do this. Past papers are the closest simulation of the actual exam and the single most effective revision tool.

How to use past papers effectively:

Phase 1: Topic-based practice (3-6 months before exams)

• After revising a topic, find past paper questions on that topic
• Attempt them under exam conditions (timed, no notes)
• Mark your answers using the official mark scheme
• Note which types of questions you got wrong

Phase 2: Full papers under timed conditions (2-3 months before exams)

• Complete entire past papers within the allocated time
• Mark strictly using the mark scheme
• Track your scores paper by paper to see improvement
• Identify patterns in the questions you consistently lose marks on

Phase 3: Targeted weak-area practice (final month)

• Compile questions on your weakest topics
• Practice these until you can consistently score full marks
• Re-do papers you scored lowest on

How many past papers should you do?

• Minimum: 3 years (6 sessions) per subject
• Ideal: 5+ years per subject
• For Maths and Sciences, aim for 10+ papers

Technique 2: Active Recall (Test Yourself Constantly)

Stop reading. Start testing.

Methods:

• Cover and recall: Read a section, cover it, write down everything you remember
• Flashcard review: Test yourself with flashcards daily
• Blank page technique: Open a blank page, write a topic title, and dump everything you know. Then check what you missed.
• Teach someone: Explain a topic to a friend, sibling, or even a stuffed animal. If you can’t explain it simply, you don’t understand it.
• Practice questions: Use textbook questions, past papers, and online question banks

The key rule: If studying doesn’t feel a bit difficult, you’re probably not learning. The effort of trying to recall information is what strengthens memory.

Technique 3: Spaced Repetition (Don’t Cram)

Cramming works for the short term but fails for exams spread over weeks. Instead:

The spacing schedule:

• Review new material after 1 day
• Review again after 3 days
• Review again after 7 days
• Review again after 14 days
• Review again after 30 days

Each review should be active (testing yourself), not passive (re-reading).

Practical implementation: Use a simple calendar system. After studying a topic:

• Write the topic and date in your planner
• Schedule review sessions at the intervals above
• During reviews, test yourself first, then fill gaps

Technique 4: Interleaving (Mix It Up)

Instead of studying one topic for hours (blocked practice), alternate between topics and subjects (interleaved practice).

Example study session:

• 25 minutes: IGCSE Chemistry — Organic Chemistry questions
• 5-minute break
• 25 minutes: IGCSE Maths — Trigonometry problems
• 5-minute break
• 25 minutes: IGCSE English — Practice essay planning
• 15-minute break

This feels harder than studying one thing at a time — but that’s precisely why it works. Your brain has to work harder to retrieve the right information, which strengthens memory.

Technique 5: Elaboration (Connect and Explain)

Don’t just memorise facts — understand why they’re true and how they connect to other ideas.

For Science subjects:

• Don’t just learn that enzymes denature at high temperatures — understand why (protein structure, hydrogen bonds, active site shape)
• Connect topics: How does photosynthesis link to respiration? How does atomic structure explain chemical bonding?

For Humanities:

• Don’t just learn that the Treaty of Versailles was harsh — explain why each clause was included and how it led to future consequences
• Connect events to broader themes and patterns

For Maths:

• Don’t just memorise formulae — understand where they come from and when to use each one
• Explain to yourself why a method works, not just how to execute it

Subject-Specific Study Strategies

IGCSE Mathematics

What makes Maths revision different: Maths is a skill subject — you can’t revise it by reading. You must practise solving problems.

Strategy:

1. Work through every past paper you can find
2. For each wrong answer, identify the specific skill gap
3. Practice that skill type until you get 5 consecutive questions right
4. Time yourself — speed matters in Maths exams
5. Learn your calculator inside out (there are functions most students never discover)

Common pitfalls:

• Losing marks for not showing working
• Making arithmetic errors under time pressure
• Not reading questions carefully (e.g., missing “give your answer to 3 significant figures”)

IGCSE Sciences (Biology, Chemistry, Physics)

Strategy:

1. Create revision flashcards for key definitions and facts
2. Practice drawing and labelling diagrams (marks are awarded for these)
3. Learn command words: “describe” ≠ “explain” ≠ “suggest”
4. Practice calculations methodically (show formula → substitution → answer with units)
5. Use past papers to identify which topics are tested most frequently

Biology-specific: Focus on processes (photosynthesis, respiration, cell division). Draw and re-draw diagrams until you can reproduce them perfectly.

Chemistry-specific: Master balancing equations, mole calculations, and ionic equations. These appear in almost every paper.

Physics-specific: Know your formulae and practice rearranging them. Physics is essentially applied Maths with context.

IGCSE English Language

Strategy:

1. Practice reading comprehension under timed conditions
2. Build vocabulary through wide reading (novels, quality journalism)
3. Learn analysis frameworks for writer’s craft questions
4. Practice different writing formats (letters, reports, articles, speeches)
5. Focus on grammar and punctuation accuracy

Key exam skill: For comprehension questions, always reference the text. Use short, embedded quotations and explain their effect.

IGCSE Economics and Business Studies

Strategy:

1. Learn and practice drawing all key diagrams from memory
2. Master the “define, explain, evaluate” essay structure
3. Use real-world examples to support your arguments
4. Practice data interpretation questions with past papers
5. Create a glossary of key terms — definitions earn easy marks

IGCSE History

Strategy:

1. Create timeline summaries for each topic
2. Practice source analysis technique (provenance, content, cross-referencing)
3. Plan essays under timed conditions (5 minutes planning, 35 minutes writing)
4. Learn to argue both sides before reaching a conclusion
5. Use specific evidence (dates, names, statistics) to support every point

• 5:15-5:30: Break
• 5:30-6:15: Subject 2 (different from Subject 1)
• 6:15-6:30: Break
• 6:30-7:15: Subject 3 (different again)
• 7:15-8:00: Dinner and free time
• 8:00-8:30: Flashcard review (all subjects, 5 mins each)

Weekends (5-6 hours of study):

• Morning: Full past paper under timed conditions
• Mark and review the paper
• Afternoon: Targeted revision on weak areas identified
• Evening: Light review (flashcards, summary sheets)

Protecting Your Wellbeing

Effective study is not about working yourself to exhaustion:

• Sleep: 8-9 hours per night. Sleep is when your brain consolidates memories. Sacrificing sleep for study is counterproductive.
• Exercise: 30 minutes of physical activity daily. It improves focus, memory, and mood.
• Breaks: Use the Pomodoro technique (25 min study, 5 min break). Take a longer break every 2 hours.
• Social time: Schedule time with friends and family. Isolation increases stress and reduces effectiveness.
• Screen breaks: Step away from screens during breaks (not more screen time).

What to Do When You’re Stuck

Topic you don’t understand:

1. Re-read the textbook section
2. Watch a YouTube explanation (search “[topic] IGCSE explained”)
3. Ask your school teacher
4. Ask a classmate who understands it
5. Work with a tutor for personalised explanation

Feeling overwhelmed:

1. Make a list of exactly what you need to cover
2. Break it into small, manageable tasks
3. Focus on one task at a time
4. Tick things off as you complete them
5. Remember: you don’t need 100% — focus on the highest-value topics

Motivation is low:

1. Review your university/career goals
2. Study with a friend for accountability
3. Change your study environment
4. Reward yourself after completing study sessions
5. Remember that motivation follows action — start studying and motivation often follows
