Active Recall and Spaced Repetition: The Only Two Techniques That Matter
How to revise effectively using active recall and spaced repetition — the two evidence-backed techniques that beat highlighting, re-reading, and cramming for IGCSE, A-Level, and IB exams.
If you want to know how to revise effectively, stop looking for hacks. Decades of learning science point to two techniques that outperform everything else: active recall and spaced repetition. They beat highlighting, re-reading, and last-minute cramming — every time. Here's how they work and how to build them into a revision timetable that actually sticks.
Why re-reading feels productive (but isn't)
Re-reading notes creates familiarity — that "I know this" feeling. Familiarity is not memory. In the exam hall, you need to retrieve information under pressure, not recognise it on a page.
Active recall forces retrieval: you test yourself, find gaps, and strengthen the neural pathways you'll need on exam day. Spaced repetition schedules those tests at intervals that maximise long-term retention.
Together, they are the foundation of every serious revision plan.
Active recall: test yourself before you feel ready
Active recall means closing the book and trying to produce the answer yourself. Methods include:
- Blank page recall: Write everything you remember about a topic, then check against notes
- Flashcards: Question on the front, answer on the back — say the answer aloud before flipping
- Practice questions: Past paper and MCQ drills without peeking at solutions
- Teach it back: Explain the topic out loud as if tutoring a friend
The 3-step active recall loop
- Learn the material once (read or watch)
- Test yourself without notes
- Fill gaps, then test again within 24 hours
If you only do step 1, you're not revising — you're browsing.
Spaced repetition: revisit at the right intervals
Spaced repetition means reviewing material at increasing intervals:
- Day 1: first learn + test
- Day 2: quick retest
- Day 4: retest again
- Day 7: retest
- Day 14: retest
- Day 30: final check before the exam
Each successful recall pushes the next review further out. Each failure resets the interval — which is exactly what you want for weak topics.
Simple spaced repetition timetable
| Day | Focus |
|---|---|
| Monday | Learn Topic A + test |
| Tuesday | Learn Topic B + retest Topic A |
| Wednesday | Learn Topic C + retest A & B |
| Thursday | Past paper questions on A–C |
| Friday | Light retest of weakest topic |
| Weekend | Rest or one short flashcard session |
This is how to make a study plan that compounds — not one that crams and forgets.
How to memorise faster (without shortcuts)
There is no magic memorisation trick. But these habits speed up genuine retention:
- Chunk information — group facts into categories (e.g. bonding types, essay structures)
- Link to what you know — analogies and worked examples beat isolated facts
- Use exam-style questions — memorise in the format you'll be tested in
- Sleep — consolidation happens during sleep; all-nighters destroy recall
Combine these with active recall and you will memorise faster than any highlighting session.
Command words and exam technique
Active recall works for exam technique too. Drill command words — describe, explain, evaluate, compare — by writing one paragraph per command word from memory, then checking against mark scheme expectations.

Build active recall into your tools
gettopmarks turns your notes into flashcards, MCQs, and practice tests — then lets you drill them until topics stick. The AI tutor explains gaps when recall fails, and Solve checks your working against examiner logic.
