Stop doing what doesn't work
The most popular revision methods are also among the weakest. Re-reading notes and textbooks builds a false sense of familiarity - the material feels easy because you've seen it before, but recognition isn't recall, and it collapses under exam pressure. Highlighting and making elaborate, colourful summaries feel like studying but are mostly passive busywork.
This is the trap of 'productive procrastination': hours spent reorganising notes or watching tutorials feel like effort while dodging the harder, more effective work. If your revision feels comfortable and easy, that's usually a warning sign, not a good one.
Make active recall your core method
The most effective thing you can do when revising is to test yourself - to close the notes and try to retrieve the information from memory. That effort of retrieval is what strengthens memory and exposes exactly what you don't yet know, which re-reading hides. Cognitive scientists call the benefit the 'testing effect', and it's one of the most reliable findings in learning research.
In practice: turn your notes into questions and answer them from memory, do a blank-page 'brain dump' of everything you know about a topic then check the gaps, use flashcards but always recall before flipping, and take practice quizzes. Anything that forces retrieval beats anything that lets you passively review.
Space your revision - don't cram
When you revise matters as much as how. The same total hours produce far more lasting memory spread across days and weeks than crammed into one session, because each spaced review resets the forgetting curve and pushes the material deeper into long-term memory. Cramming can rescue tomorrow's test but fades within days.
So start early enough to spread your revision out, and revisit each topic several times with growing gaps between reviews - a day, a few days, a week. Bring topics back sooner when you get them wrong and push them out when you get them right. Spacing plus active recall is the backbone of every effective revision plan.
Use past papers and practice questions
Past papers are revision gold. They force retrieval, show you the real question styles and wording, build the speed you need under time pressure, and reveal exactly which topics you're weak on. Doing them under timed, exam-like conditions also rehearses the experience so the real thing feels familiar.
Treat every practice paper as a diagnostic, not just a score. Mark it honestly, work out why you lost each mark - a knowledge gap, a careless slip, or a timing issue - and feed those weaknesses straight back into your next active-recall session. Revision that's driven by your own mistakes is revision that works.
