The techniques that work (high evidence)
Two methods stand far above the rest in research by Dunlosky and colleagues: active recall (testing yourself, retrieving information from memory rather than re-reading) and spaced repetition (reviewing material at increasing intervals rather than cramming). Together these form the backbone of effective revision. Practical applications: flashcards, past papers done from memory, the 'blurting' method (write everything you know about a topic, then check gaps), and teaching the material aloud. Our free revision planner builds both methods in.
The techniques that waste time (low evidence)
The most popular revision methods are among the least effective. Re-reading notes and textbooks creates a false sense of familiarity without building recall. Highlighting is largely passive and gives the illusion of productivity. Copying out notes neatly feels like work but involves little active thinking. These methods feel comfortable precisely because they're easy — and that ease is the problem. Effective revision should feel effortful, because the effort of retrieval is what builds memory.
Building an effective revision routine
Combine the methods: study a topic, then test yourself on it the same day, again the next day, then after 3 days, then a week (spaced repetition). Use past papers extensively — they're the closest thing to the real test and reveal exactly what you don't know. Interleave subjects (mixing topics rather than blocking one subject for hours) improves long-term retention. Use the Pomodoro technique to maintain focus, and track weak topics so revision time goes where it's most needed.
