How to Build an Exam Revision Timetable That Works

A step-by-step method for planning revision: share your hours between subjects by exam date and difficulty, add practice testing, and export the plan to your calendar.

Most revision plans fail for two reasons: they are too optimistic about the hours available, and they treat every subject the same. A good timetable starts from the time you really have, gives more of it to harder subjects and nearer exams, and leaves room for practice papers and rest. This guide shows a method you can follow by hand or with the Exam Revision Scheduler.

Step 1: list your exams and count the days

Write each subject with its exam date, then count the days left. The Date Difference Calculator will do it for you. Note the order of the exams: the last exam gives you the most days, but you cannot start serious work on it while you are still sitting the earlier ones.

Step 2: rate each subject

Give each subject a difficulty from 1 to 5, based on how confident you feel, not how much you like it. A subject you find hard, with lots of content, should score 4 or 5. Be honest: students tend to revise the subjects they enjoy and avoid the ones they need most.

Step 3: count the hours you really have

Start with school, work, travel, meals, sleep and commitments, and write down what is left. Be realistic. Two and a half hours on a weekday and five on a weekend is a sustainable pattern for many students, and it is better to plan slightly fewer hours and keep to them than to plan a heroic schedule and abandon it by Wednesday.

Step 4: use short sessions with breaks

Sessions of 25 to 50 minutes with a break after each hold attention better than long unbroken stretches. At 50 minutes a session, 2.5 hours gives you three sessions on a weekday, and five hours gives you six on a weekend day. Use one rest day a week if you can.

Step 5: share the sessions between subjects

The simplest fair rule is to give each subject more sessions the harder it is and the sooner its exam. The scheduler weights each subject by its difficulty divided by the square root of the days left, then shares each day's sessions in proportion. A subject stops being scheduled the day before its exam, so time then flows to the exams still ahead.

A worked example

Three exams: Maths on 2 November (difficulty 4), Biology on 5 November (3) and English Literature on 9 November (2). Revision starts Monday 19 October, with 2.5 hours on weekdays and 5 hours on weekends, in 50-minute sessions.

Over 21 study days that is 81 sessions, about 67.5 hours. Notice that English, the easiest subject, ends up with the most sessions. That is not a mistake: it has the latest exam, so once Maths and Biology are finished its last four days are entirely devoted to English. In the first week, all three subjects share each weekday, with Maths getting the extra weekend sessions. Your own plan will differ with your dates and hours.

Make the time count: how to revise

• Test yourself. Research on learning keeps finding that trying to recall information beats re-reading it. Use flashcards, past papers and questions. The Study Notes to Practice Quiz turns your notes into fill-in-the-blank and definition questions with the source sentence for each answer.
• Space it out. Return to each topic several times over days and weeks, instead of cramming it in one session.
• Mix topics. Switching between topics within a subject, and between subjects, feels harder but helps you tell similar ideas apart.
• Do past papers under timed conditions in the last weeks, then mark them and fix the gaps.
• Sleep. Memory consolidates during sleep, so late-night cramming usually costs more than it gains.

Leave room for the unexpected

Do not fill every hour. Keep one free slot each week as a buffer for illness, a bad day or a topic that needs longer, and review the plan every weekend. If a subject is going better than expected, move sessions to the one that is not.

Put it in your calendar

A plan on paper is easy to ignore. The scheduler can download your sessions as a calendar file (.ics) that you import into Google Calendar, Outlook or Apple Calendar, so each session turns up with a reminder. Edit or delete sessions there as your week changes.

Frequently asked questions

How many hours a day should I revise? It depends on your course and exams. Quality matters more than totals: a few focused hours with breaks beat a long day of tired reading.

What if two exams fall close together? The scheduler will give both subjects regular sessions until the first exam, then move all time to the second. Do a light review of the first subject the night before it, not new material.
