Most revision timetables die within a week. Someone spends a Sunday afternoon colour-coding a beautiful grid, pins it above their desk, and by the following Friday it has been quietly abandoned. The problem is rarely a lack of willpower. It is usually that the timetable was never realistic in the first place.
A good timetable does two things: it shows you when you are going to revise, and it survives contact with real life (the nights you have football, the days you feel wiped out, the topics that turn out to be harder than expected). This guide walks through building that kind of timetable, whether you are revising for GCSEs, A-Levels, mocks, or any other set of exams.
8-12 weeks – A sensible planning window. Most students benefit from starting a structured timetable two to three months before their first paper, leaving room for buffer time and topic reprioritisation Our Year 11 revision timetable maps a complete six-month countdown with monthly priority adjustments.
Step 1: Audit the time you really have
Before you decide what to revise, work out when you can revise. Open a blank weekly grid, seven columns for the days, hourly rows down the side, and start by marking everything you cannot move.
School or college hours go in first. Then commutes, meals, part-time work, sports training, family commitments, anything that is genuinely fixed. Include sleep too. NHS and Sleep Foundation guidance for 13 to 18 year olds is eight to ten hours a night, and skipping sleep to revise is one of the fastest ways to make your revision less effective.
What you have left is your revision budget. For most students this is two or three hours on a school evening and five or six hours on a weekend day, with more in the holidays. If the total looks smaller than you hoped, that is useful information, not a problem. Planning around fantasy hours is what kills timetables in week two.
If you tell yourself you will revise from 8am to 10pm on a Saturday, you will not. Be honest about your actual capacity. Four productive hours beats twelve theoretical ones every time.
Step 2: Prioritise your subjects
Not every subject needs the same amount of time. Splitting your hours evenly across everything means you spend just as long on topics you already know as on the ones costing you grades. That is a poor return on your time.
Sort your subjects into three tiers. High priority is anything where you are well below your target grade, or where the content is dense and unfamiliar. Medium priority is subjects where you are close to target but have specific weak topics. Low priority is subjects you are already performing well in, which still need regular contact but not the bulk of your hours.
Roughly speaking, aim for about twice as many sessions per week on high-priority subjects as on low-priority ones. Your strong subjects still need maintenance sessions, they just do not need the heavy lifting. Revisit your tiers every two to three weeks, because priorities shift as you revise.
Step 3: Choose your session length
Long revision sessions feel productive but rarely are. Some research suggests focused attention tends to fade somewhere between 30 and 50 minutes of continuous work, and it varies a lot by person and task. Beyond that point, you are still at your desk, but you tend to absorb less. Our guide to how long a revision session should be goes into the science in more detail.
For most subjects, block your time into 25 to 50 minute sessions with a 5 to 10 minute break between each one. Content-heavy subjects like GCSE biology or history often suit shorter blocks with active recall. Problem-solving subjects like GCSE maths or physics can handle slightly longer blocks because you need time to work through multi-step questions.
Give every session a specific goal. "Chemistry" is not a plan. "Chemistry: Balancing equations, questions 1 to 15" is. A concrete goal tells you when the session is finished and stops you from drifting into passive re-reading. Our guide to revising effectively covers the specific techniques that work best inside each session.

Rather than revising the same subject two days in a row, rotate across the week so each subject gets several contacts. Interleaving different subjects has been shown to improve long-term recall compared to blocking one subject at a time.
A sensible pattern is to touch every subject at least twice a week, with high-priority ones landing three or four times. Mix problem-solving subjects with content-heavy ones across a single evening so your brain gets variety. Keep essay subjects for the times when you are freshest, because they demand the most sustained thinking.
The table below shows a sample week for a student sitting nine GCSE subjects, with maths and biology as high priority and history and French as lower priority. Adapt the shape to your own subjects and available hours.
| Day | After school (2 sessions) | Evening (2 sessions) |
|---|---|---|
| Monday | Maths, English literature | Biology, French |
| Tuesday | Chemistry, geography | Maths, English language |
| Wednesday | Rest / catch-up | Rest / catch-up |
| Thursday | Physics, history | Biology, RE |
| Friday | Maths, French | Free evening |
| Saturday | Chemistry, biology, English literature (morning) | English language, geography (afternoon) |
| Sunday | Physics, maths (morning) | Review + plan next week (evening) |
Notice what this sample does: Wednesday is a full rest day, Friday evening is free, and Sunday evening is a short planning slot rather than another revision session. Building rest and planning into the week is what keeps the timetable alive past week two.
Step 5: Leave buffer slots for slippage
You will fall behind at some point, and everyone does. A bad day, a topic that takes longer than expected, an unexpected event, all of it happens.
The fix is to bake slippage into the plan from the start. Leave two or three empty slots each week that are not assigned to any subject. When something goes wrong, you slot the missed session into a buffer instead of trying to cram it on top of an already full day. If nothing goes wrong, use the buffer for whatever felt shakiest that week.
If you fall behind by more than a few sessions, do not try to recover everything. Look at your priority tiers, protect the high-priority ones, and let the rest go. A timetable you are chronically behind on stops being motivating, so it is better to reset and move forward than to drag a growing backlog around. If chronic avoidance is the pattern, our piece on how to stop procrastinating with revision may help.
Falling behind is not failure so much as information: a missed week tells you your plan was slightly too ambitious, and now you know exactly where to adjust.
Step 6: Pick a format you will use
The best timetable format is the one you will genuinely check. Paper grids stuck above your desk work if you sit there every day. Google Calendar or Notion works if your phone is where you live. Printable weekly templates suit students who like ticking boxes and rewriting each week from scratch.
Whatever you pick, keep it visible and keep it simple. If your timetable takes half an hour to update each week, you will stop updating it. If it lives buried in a folder you never open, it might as well not exist.
Step 7: Review and adjust every week
A timetable is a plan, not a contract. Spend ten minutes at the end of each week looking back. Which sessions worked? Which ones did you skip? Was anything easier or harder than expected? Did any topic need more time?
Use those answers to tweak the following week. Move sessions to times that suited you better. Add an extra slot for a topic that turned out to be harder. Drop a session from a subject you have made real progress in. Small weekly adjustments keep the timetable useful. Big overhauls every three weeks usually mean the plan was never quite right in the first place.
Work through this list the first time you sit down to plan. Twenty to thirty minutes should be enough.
- Map every fixed weekly commitment onto a blank grid
- Write down your genuine available hours per day
- Sort your subjects into high, medium, and low priority
- Allocate roughly twice as many sessions to high-priority subjects
- Break sessions into 25 to 50 minute focused blocks
- Write a specific goal for every session, not just a subject name
- Include at least one full rest day per week
- Leave two or three unassigned buffer slots each week
- Choose a format (paper, calendar, app) you will keep visible
- Schedule a 10-minute weekly review to update the plan
