There's a certain kind of revision timetable that takes a whole Sunday to make: rainbow-coloured, blocked out to the half-hour, laminated with pride. It looks incredible. It also tends to be abandoned by the following Wednesday. A timetable that works is usually uglier and far simpler. Here's how to build one.

Start with the exams, not the subjects

List every exam with its date. The subjects with the nearest exams, or the ones you find hardest, get more slots. It sounds obvious, but plenty of students spend equal time on everything and then run out of runway on the subject that needed the most.

Work in short blocks, with breaks

Aim for blocks of around 25 to 40 minutes with a proper break between them. Long unbroken sessions feel virtuous but your attention falls off a cliff after about 45 minutes. Two focused half-hours beat one exhausted two-hour slog.

The rule that makes it stick: space it out

Here's where most timetables go wrong. They spend a whole day on one topic, tick it off, and never come back. But you forget most of what you learn within a few days unless you revisit it. So build in spacing: touch each topic several times across the weeks, not once. A quick review of Monday's topic on Thursday is worth more than another brand-new topic.

Make every block active

A timetable slot that just says “read biology notes” is a slot you'll get nothing from. Every block should involve answering questions from memory, not re-reading. Write the block as a task with an output: “do 15 questions on the heart”, not “revise the heart”.

A simple template

  • Mon–Fri: two or three 30-minute blocks after school.
  • Weekends: a few more blocks, still with real breaks and a day off.
  • Every block: one topic, questions from memory, mark yourself.
  • Every few days: a “come back to it” block on something from last week.

Let something else do the scheduling

The hardest part of a timetable is the spacing admin: remembering which topic is due for a revisit and when. That's exactly the sort of thing software is good at and humans are terrible at. Tools like Revision Genie take care of the timing automatically: you just answer a few questions each day, and it brings topics back at the right moment so you don't have to plan every revisit yourself. Free, from KS2 and KS3 through GCSE and A-level, and built by the same team as AnswerBoards. Pair it with a light timetable and you've got a plan you'll actually keep.
