How to make a revision timetable that actually works

A good revision timetable starts from your exam dates and the hours you can genuinely study, gives more time to harder and nearer subjects, spreads each subject out over weeks instead of cramming it, mixes subjects within a day, and fills each session with active recall rather than rereading. It also leaves slack, because plans that assume a perfect week fail on the first bad day. I built the study planner to do the scheduling, and this guide explains the reasoning behind each choice.

Start with dates and real hours

List every exam with its date, then decide how many hours you can actually study on each day of the week, not how many you wish you could. School, work, travel, sport and sleep come first. Then pick a session length that fits those hours. This matters more than it looks: two hours split into 45-minute sessions gives two sessions and 30 spare minutes. With the planner's default week of 2 hours Monday to Thursday, 1½ on Friday, 3 on Saturday and Sunday off, 45-minute sessions give 12 sessions or 9 hours a week, 60-minute sessions give 12 hours, and 25-minute Pomodoro sessions give 26 sessions, about 10.8 hours. Choose a length that uses your time well and suits your concentration. Does the Pomodoro technique actually work? explains the short-session approach, and the Pomodoro timer keeps the rhythm.

Share time by difficulty and nearness

Equal time for every subject wastes hours on easy ones. Rate each subject's difficulty for you, then weight by how soon the exam is. The planner multiplies a 1-to-5 difficulty rating by a factor that grows as the exam approaches, so a hard subject with an exam a month away and a medium subject with an exam in ten days get similar shares, and anything three days away jumps to the front. You can do the same on paper: give each subject points for difficulty, add a few for nearness, and divide the week's sessions in proportion.

Space it out and mix subjects

Two findings from memory research shape a good timetable. The spacing effect: material reviewed several times with growing gaps is remembered far longer than the same time spent in one block, which is why cramming fades so quickly. And interleaving, also called varied or mixed practice: switching between subjects or problem types within a session or day feels harder, but it helps you learn to tell problems apart and choose the right method. So aim for two or three different subjects each day rather than one subject all day, and bring each topic back after a day, a few days, a week and a couple of weeks. The planner mixes subjects within each day, and when a subject comes round again 1, 3, 7, 14 or 28 days after you first studied it, the session is marked as a review. Spaced repetition, explained properly explains the forgetting curve behind those gaps.

What to do in each session

The timetable plans time, not content, so give each session a specific topic: "quadratic equations", not just "maths". Then spend it on retrieval practice, pulling information out of memory rather than putting it back in. Research on the testing effect shows that practising recall strengthens memory more than rereading or highlighting, even though rereading feels more comfortable. Practical forms:

• Close the book and write down everything you remember, then check the gaps.
• Answer practice questions or past-paper questions on the topic.
• Quiz yourself with flashcards; the flashcards tool keeps decks between sessions.
• Explain the topic aloud as if teaching it.

The last days before an exam

In the final few days, shift from learning new material to rehearsing the exam itself: timed past papers, the mark scheme and your weakest topics. The planner switches each subject to past papers in its last three days and gives it a final review the day before. Keep that final review light; the night before an exam is for consolidating, not starting something new, and a full night's sleep matters for memory, so protect it.

Keeping it realistic

Build in at least one lighter or free day a week, and do not fill every available minute; spare sessions absorb illness, extra homework and bad days. Tick sessions off as you go, since visible progress helps motivation. If you fall more than a few days behind, do not try to catch up by doubling the load; re-make the timetable from today with the time you have left. For the rest of each day, the daily planner turns the timetable into a schedule that fits around everything else.
