Study & writing
Revision timetable calculator
Enter when your exams are, how many subjects you cover and the hours you can study each day; get the hours and sessions per subject.
Count a session as roughly one hour. Rest days are spread through each week, not fixed to the weekend.
How your time is divided
The timetable counts every day from today to the day before your exam, keeps the study days you have by setting aside your rest days each week, and then shares the time equally between your subjects. Total study hours are the study days multiplied by your hours per day. Each subject gets an equal slice: hours per subject = total study hours ÷ number of subjects. Splitting your daily hours into roughly one-hour sessions gives the number of sessions per day, and rotating subjects through those sessions keeps every subject warm instead of cramming one at a time.
Worked example: exams in 14 days, 4 subjects, 3 hours a day, 1 rest day a week. That leaves 12 study days, so 12 × 3 = 36 study hours. Divided across 4 subjects, each subject gets 9 hours, which at one-hour sessions is 9 sessions per subject spread through the run-up. Three sessions a day means you touch three different subjects daily and cover all four every weekday-and-a-bit.
| Subjects | Hours each (36 total) | Sessions each |
|---|---|---|
| 3 | 12.0 h | 12 |
| 4 | 9.0 h | 9 |
| 5 | 7.2 h | 7.2 |
| 6 | 6.0 h | 6 |
Using the timetable well
An equal split is the fair starting point, but few students need every subject equally. Once you see the per-subject hours, shift time from the subjects you are confident in toward the ones that scare you or carry the most marks; the calculator gives you the budget, and you decide how to spend it. Rotating subjects within a day, rather than devoting whole days to one, uses interleaving, which research on study methods links to better long-term recall than blocking a single topic for hours.
Keep the sessions active: past papers, self-testing and explaining a topic out loud beat rereading notes. Guard at least one rest day a week over a multi-week run, because tired revision is slow and poorly remembered, and a timetable with no slack falls apart the first time life interferes. If the plan asks for more than about eight hours a day, it is a sign you have left too little time; starting the timetable earlier is the only real fix. This tool spreads a whole exam season across subjects, which is different from drilling the rounds of review for a single subject.
Frequently asked questions
How many hours should I revise for each subject?
Divide your total study hours equally, then adjust. With 36 hours across 4 subjects that is 9 hours each; give more to weaker or higher-weighted subjects and less to your strongest.
Is it better to study one subject a day or several?
Rotating several subjects a day (interleaving) tends to improve long-term recall compared with spending whole days on one topic, because switching forces your brain to retrieve rather than re-read.
How many rest days should a revision timetable have?
About one a week over a multi-week plan keeps the other days productive and leaves a buffer for illness or emergencies. Revising while exhausted wastes time you could have used well.
