STUDY METHODS THAT
ACTUALLY WORK
(AND THE ONES THAT DON'T)
RE-READING AND HIGHLIGHTING FEEL PRODUCTIVE — BUT AREN'T
Reading a page for the third time makes it look familiar, and your brain mistakes that familiarity for actual knowledge. This is called the illusion of competence — you recognise the material when it's in front of you, but the moment it's an exam question with no notes nearby, that recognition doesn't transfer into recall.
PASSIVE STUDYING VS ACTIVE STUDYING
Passive methods — reading, highlighting, watching a video without pausing — put information in front of your eyes. Active methods — testing yourself, explaining a concept out loud, solving a problem from scratch — force your brain to pull information out of memory. That retrieval effort is what actually strengthens the memory, not the exposure.
THE FORGETTING CURVE — WHY CRAMMING LOSES TO SPACING
Without review, memory of new material drops off sharply within a day or two — most of what you crammed the night before an exam has already started fading before you even walk into the hall. Reviewing material at increasing intervals resets that curve each time, which is why the same total hours spent spread out beats the same hours crammed into one session.
ACTIVE RECALL — TEST YOURSELF, DON'T RE-READ
Close the book and try to write or say everything you remember about a topic before checking your notes. Use flashcards, blank-page recall, or past paper questions — anything that forces retrieval rather than recognition. This is consistently one of the most effective study techniques there is, and it's also the one students use least, because it feels harder than re-reading.
SPACED REPETITION — REVIEW BEFORE YOU FORGET, NOT AFTER
Instead of studying a topic once and moving on, revisit it after 1 day, then 3 days, then a week, then two weeks. Each review should happen right around when you're starting to forget — that's when retrieval is hardest and most effective at rebuilding the memory. A simple written schedule or app-based flashcard system works fine; the spacing matters more than the tool.
THE FEYNMAN TECHNIQUE — TEACH IT TO FIND THE GAPS
Pick a concept and explain it out loud in the simplest language possible, as if teaching a younger student who's never heard of it. The moment you stumble, get vague, or reach for jargon to cover a gap — that's exactly where your understanding breaks down. Go back to that specific gap, fix it, then try explaining the whole thing again from the start.
INTERLEAVING — MIX TOPICS INSTEAD OF BLOCKING THEM
Studying one topic for a full two hours (blocking) feels organised, but switching between related topics or question types within a session (interleaving) forces your brain to actively decide which method applies each time — much closer to what an actual exam demands, where questions aren't grouped by topic for you.
TURN YOUR NOTES INTO QUESTIONS, NOT SUMMARIES
After a class or a reading session, don't just summarise what you learned — rewrite it as a set of questions you could be asked. This does two things at once: it forces active processing while the material is fresh, and it hands you ready-made active recall material for every future review session.
BUILD A SPACED REVIEW SCHEDULE AROUND YOUR EXAM CALENDAR
Work backward from your exam dates and plan review sessions for each topic at increasing intervals, rather than only revisiting things once, right before the test. This is where a proper study schedule and spaced repetition meet — the schedule isn't just about finding time to study, it's about controlling exactly when each topic gets reviewed.
PAST PAPERS ARE ACTIVE RECALL AND INTERLEAVING IN ONE
A timed past paper forces retrieval under pressure, mixes question types the way a real exam does, and gives you an immediate, honest measure of what actually stuck versus what only felt familiar. If you only have time for one method this week, sitting and marking a past paper properly covers more of the evidence-backed ground than any other single activity.
