The Best Revision Techniques for Exams, Backed by Research
Last updated: 14 November 2026
With January exams and mocks approaching, how you revise matters as much as how long you revise. Research into learning shows that some popular habits, such as re-reading notes and highlighting, are far less effective than methods that make your brain work harder to retrieve information. Here are the best revision techniques, ranked by the evidence, plus a simple timetable you can copy.
What the Research Says
A major review of learning techniques by psychologist John Dunlosky and colleagues (2013) rated practice testing and distributed (spaced) practice as the most effective study methods. Highlighting and re-reading were rated low, because they feel productive but do little to strengthen long-term memory.
| Technique | Effectiveness | Best for |
|---|---|---|
| Active recall (practice testing) | High | Every subject |
| Spaced repetition | High | Facts, vocabulary, definitions, formulas |
| Past papers | High | Exam technique and timing |
| Interleaving | Moderate to high | Maths, science, problem-solving |
| Elaboration and self-explanation | Moderate | Understanding concepts |
| Re-reading notes | Low | A final quick review only |
| Highlighting | Low | Marking key points to test yourself on later |
1. Active Recall
Close your notes and try to write down or say everything you remember about a topic, then check what you missed. Flashcards, practice questions and “brain dumps” all use active recall. The effort of retrieving information is what makes it stick.
2. Spaced Repetition
Review material at increasing intervals, for example after one day, three days, one week and two weeks. Apps such as Anki, or a simple Leitner box system for paper flashcards, schedule reviews for you. Spacing beats cramming the same hours into one night.
3. Past Papers and Mark Schemes
Practise under timed conditions, then mark your work against the official mark scheme. This shows you what examiners reward and builds exam stamina. For university exams, ask your module leader for past papers or sample questions.
4. Interleaving
Mix different topics or problem types in one session instead of doing all of one type in a block. It feels harder, but it trains you to recognise which method to use, which is exactly what exams test.
5. The Feynman Technique
Explain a topic in simple words as if teaching a younger student. Wherever you get stuck or reach for jargon, you have found a gap to go back and fix.
6. The Pomodoro Technique
Work in focused 25-minute blocks with 5-minute breaks, taking a longer break after four blocks. It helps you start, stay focused and avoid burnout.
7. Mind Maps and Concept Maps
Drawing links between ideas helps with essay subjects and big-picture understanding. Make them from memory first, then check against your notes, so you are using recall too.
8. Sleep, Exercise and Breaks
Memories are consolidated during sleep, so all-nighters work against you. Regular exercise, meals and time off keep your concentration up across a long revision period.
Sample Revision Timetable (4 Weeks Before Exams)
| Week | Focus |
|---|---|
| Week 1 | List every topic, rate your confidence and make flashcards for weak areas |
| Week 2 | Active recall and spaced reviews on all topics; start timed questions |
| Week 3 | Full past papers under exam conditions; revisit weak topics |
| Week 4 | Mixed (interleaved) practice, light reviews and plenty of sleep |
Common Revision Mistakes
- Re-reading notes and mistaking familiarity for knowledge.
- Spending hours making pretty notes instead of testing yourself.
- Only revising topics you already like.
- Cramming the night before.
- Studying with your phone within reach.
Frequently Asked Questions
What is the most effective revision technique?
Active recall (testing yourself) combined with spaced repetition is the most effective approach, according to research on learning.
How many hours a day should I revise?
Quality matters more than hours. Many students find 4–6 focused hours a day, in short blocks with breaks, is sustainable in the weeks before exams.
Is highlighting a good way to revise?
Not on its own. Use highlighting only to mark points you will turn into questions or flashcards.
How far in advance should I start revising?
Ideally four to six weeks before exams, so you have time to space out your reviews.
