How to Build a Revision Timetable That You Will Actually Follow (GCSE and A-Level)

Before you plan a single session, write the exam dates down in order. Exam boards publish their timetables the summer before, and your school will confirm them by about February. For a typical GCSE student, that is 20 to 25 papers spread over five or six weeks from early May to late June. For A-level it is nearer 9 to 12 papers over roughly the same window. The order matters far more than most students realise: a subject examined on 6 May needs its revision finished by 5 May, while a subject examined on 20 June can be started later and revised during the exam period itself.

Count the weeks from today to the first exam. That is your planning window. Then count the weeks from the first exam to the last; that is your exam period, and it has its own timetable, which we cover in the final section. If you are reading this in September, you have about 30 weeks, which is plenty. If you are reading it at Easter, you have six, which is tight but workable if the weighting in Step 2 is honest.

The most common mistake we see is giving every subject the same number of hours. Equal time is fair to the subjects, and unfair to you. The subject you already have a grade 7 in does not need as much time as the one you are scraping a 4 in, and the subject with three papers needs more than the one with one. We use a simple score: rate each subject from 1 (confident) to 3 (worried), multiply by the number of papers, and add 1 for any subject that is a requirement for your next step (English and maths for most sixth forms; a specific A-level for a university offer). The result is the weight, and the weights are turned into a share of the week's sessions.

Science gets six sessions a week and history gets one, and that is correct for this student. Redo the scores every four weeks, because confidence changes: a subject that was a 3 in January is often a 2 by March, and the sessions it frees up should go to whatever has become the new worry.

We are wary of anyone who tells you the perfect session length, because the research on attention is less tidy than the study-tips industry suggests. What we can say from experience is that sessions under 25 minutes rarely get past the setting-up stage, and sessions over an hour without a break turn into reading with the eyes only. A 45-minute session followed by a 15-minute break is a sensible default for most students; some prefer two 25-minute blocks with a five-minute gap, and that is fine too. The break needs to be a real break, standing up and away from the desk, not a change of screen.

What is better supported is that testing yourself beats re-reading, and that revisiting a topic a few days after first covering it beats covering it once for longer. So a session should end with five minutes of closed-book recall (past-paper questions, flashcards, writing out what you remember), and the timetable should bring each topic back at least twice before the exam. Plan on 20 sessions a week during term time, which is three on a school day and four or five at the weekend. That is roughly 15 hours, and it is more than most students actually do, so treat it as a ceiling rather than a floor.

Here is a two-week grid for the student in the weighting table. Each cell is one 45-minute session, using the subject codes above. School days have an early-evening slot and two later slots; weekends have a morning and an afternoon. The empty cells are not forgotten; they are rest, and they are on the grid on purpose so that nobody fills them. The Wednesday evening off is a standing club; Sunday afternoon is family time. Both are fixed before any subject is placed.

Count the codes across both weeks and you get maths 8, science 12, French 5, English language 4, English literature 4, history 1, geography 1 and art 1, which is 36 sessions, or 18 a week: two fewer than the weighting table planned, because the grid is honest about Friday evening. Better to plan 18 and do 18 than plan 24 and do 12 while feeling guilty. The two-week block repeats, which is the same principle as a repeating shift pattern: build the cycle once, roll it forward, and only edit the exceptions.

Look again at the grid and you will see that no evening has the same subject twice, and no subject appears on consecutive slots. This is deliberate. Interleaving, which is the name for mixing subjects within a day, feels harder than doing three hours of maths in a row, and that feeling is a sign that it is working: you are having to retrieve rather than coast. The one exception is the weekend morning, where a double session on the heaviest subject lets you do a full past paper under timed conditions, which is the single most useful revision activity there is for most subjects.

Rest days are not optional. One full day off a week in the planning window, dropping to a half-day in the exam period, is what keeps the other six days productive. Students who plan seven days a week revise for about ten before something gives, and then lose a whole week to it. Put the rest day on the grid, and if it is Sunday, protect it the way a night-shift worker protects the recovery day after a block, for the same reason: see our guide to planning for fatigue for how that works in a workplace rota.

Mock results, usually back in January or February, are the best information you will get about where the timetable is wrong. Redo the weighting table with the mock grades in the confidence column. Anything that came in two grades or more below target goes to a 3. Anything at or above target drops a point. Then rebuild the sessions per week from the new weights. In our experience this moves three or four sessions a week from one subject to another, which is enough to matter and small enough not to disrupt the habit.

Also look at the individual papers. A student who got a 6 in maths overall but a 3 on the non-calculator paper does not need more maths in general; they need the non-calculator paper specifically, and the session code on the grid can say so (MA-NC rather than MA). The more precise the code, the less time is lost deciding what to do when the session starts.

Once the exams begin, the weekly grid stops working, because the day after a paper is not the same as the day before one. Switch to a day-by-day plan for the exam period, built directly off the exam dates. The evening before an exam is that subject only, and it is recall and past-paper questions rather than new material. The morning of an exam is 30 minutes of the same, then nothing. The afternoon after an exam is off; the evening is the next subject. Do not revise a subject you have already sat, and do not go over the paper you just did with friends, because there is nothing to gain and a great deal of confidence to lose.

Sleep matters more than the last two hours of revision. Most students who go badly wrong in an exam do so because they are tired, not because they missed a topic. Keep the same bedtime through the exam period as you kept in the planning window, and if a subject is not ready the night before, accept it and sleep anyway.

A last note for parents. The best thing you can do with a revision timetable is not to enforce it but to protect it: keep the chore rota light for those weeks, keep the house quiet in the evening slots, and ask how the session went rather than whether it happened. The study roster is built for exactly this, but a sheet of paper on the fridge works nearly as well, provided it was built the way this guide describes.
