How to revise for university exams (a method that actually works)

Most students revise the way they were taught to at school: re-read the notes, highlight the important bits, re-read the highlights. It feels productive because the material starts to look familiar. Familiar is not the same as remembered, and an exam asks you to produce the answer, not to recognise it.

Learning research has been unusually consistent about what works instead. The method below is built on two of the best-supported techniques there are, and it fits around a normal university timetable.

You cannot recall what you never understood. After each lecture, go through the slides or your notes once, slowly, and make sure you could explain every heading to a friend. Look up what you do not follow while it is fresh — the week before the exam is a bad time to discover a gap in week three.

This is the only step where reading is the main activity. Keep it short: the goal is understanding, not memorising.

Rewrite each lecture as questions with short answers — one idea per question. "What does the sodium–potassium pump do?" is a good question. "Explain membrane transport" is a chapter, and you will skim it.

• Ask for one fact, definition, mechanism or step per question.
• Write the answer in your own words, short enough to check at a glance.
• Add the question you got wrong in a seminar or past paper — those are gold.

Then answer the questions with the answer covered. Saying or writing the answer before you check it is the whole point: in a well-known experiment, students who tested themselves on a text remembered more of it a week later than students who spent the same time re-reading it, even though the re-readers did better five minutes after studying.

Coming back to the same questions after a gap beats doing them all in one long session. A large review of the research on spacing found the benefit across hundreds of experiments, and showed that the further away the test, the longer the useful gap between sessions.

In practice: revisit a lecture's questions the next day, then a few days later, then a week later, then every couple of weeks until the exam. Questions you answer easily move further apart; questions you miss come back sooner.

In the last two or three weeks, add timed practice: past papers if your department publishes them, mock questions if it does not. Do them without notes, against the clock, then mark them honestly. This trains the thing the exam actually measures — producing a structured answer under time pressure — and shows you which topics still need step 3.

For a term with four modules, an hour or two on most days is enough if you start early. Adjust the blocks to your own timetable.

• Re-reading notes as the main activity. It builds familiarity, not recall.
• Highlighting. A review of ten common techniques rated it among the least useful.
• Cramming everything into the last week. The same hours spread out are worth more.
• Skipping the questions you keep getting wrong. Those are the ones the schedule exists for.
• Making questions too big. If an answer takes a paragraph, split the question.

If a technique feels easy, it is probably not doing much. Effortful recall is the part that makes things stick.

Everything above works with paper cards and a calendar, and plenty of students do it that way. The cost is time: writing the questions for every lecture, and keeping track of what is due when.

StudyFi takes over those two jobs. You upload the lecture slides or notes and it writes the flashcards and a scored quiz from them; on the paid plans it also schedules the reviews, so each day you only open what is due. Check the cards it makes — they come from your material, but you know your course best.
