How to Make a Revision Timetable That You Will Actually Follow

To make a revision timetable, work backwards from your exam dates: count the hours you can really study, list every topic you need to cover, share the hours out by how weak and how heavy each topic is, put the earliest exams first, and leave empty slots for catch-up and review. The plan should fit on one page and should be easy to change when the week does not go to plan.

Most timetables fail for the same reason: they describe the student you wish you were. Every evening is filled, every subject gets equal time and there is no room for a bad day. By the third day it is a coloured piece of paper you feel guilty about. A timetable that works is boring and realistic, and it is built from facts instead of hopes.

Why a timetable helps, and what it cannot do

A timetable helps with two things. First, it removes the daily decision of what to work on. Deciding costs energy, and "I do not know where to start" is one of the most common ways an evening disappears. Second, it spreads your study over time. Research on the spacing effect, including a large review by Cepeda and colleagues in 2006, found that learning spread across several sessions is remembered better than the same time packed into one. A timetable is the easiest way to spread study out on purpose.

What a timetable cannot do is make the sessions good. A perfect plan filled with rereading is still rereading. The schedule decides when you study; the method decides how well it works. So build your plan around methods that test you, such as active recall and spaced repetition, instead of long blocks labelled "read chapter 4".

Step 1: Write down your exam dates and work backwards

Start with facts. List every exam with its date, its subject and, if you know it, the time of day. Add anything else that eats your calendar before the exams: coursework deadlines, trips, a job, family events, sports.

Then count the days between today and each exam. This number is your budget, and it is often smaller than you expected. Many students are surprised to find they have 5 weeks rather than the 10 they felt they had.

Mark the last two days before each exam as "light". These are for final checks and sleep, not new material. If two exams are close together, the first one's final day and the second one's first day will overlap, and you need to see that now rather than on the night.

Step 2: Count the hours you can really study

Take one ordinary week and cross out everything that is not available: school or lectures, travel, meals, sleep, training, commitments. What is left is your real study time.

Now be honest about the quality of those hours. Most people can concentrate for about three to five hours a day on demanding work. After that, extra hours mostly produce the feeling of studying. So take the hours that are left, then schedule roughly 70 percent of them. The rest is your buffer for sickness, tiredness and the unexpected.

A rough weekly example: you have 20 free hours on weekdays and 12 at the weekend. Schedule about 22 of those 32 hours. The other 10 stay empty on purpose, and they are the reason the plan survives.

Step 3: List the topics, not the subjects

"Chemistry" cannot be revised, because nobody knows where to start. "Chemistry: acids and bases, 45 minutes" can. Take the syllabus or the course outline for each exam and break every subject into its topics. Aim for items that can be revised in one to three sessions.

For each topic, give it a quick rating from 1 to 3 on how confident you are, where 1 is "I could teach it" and 3 is "I do not know what this is". Be honest. A useful trick is to try three questions on the topic without notes. Whatever you cannot answer is a 3.

This rating turns a vague worry into a list you can act on. It also protects you from the most common scheduling error, which is giving the same time to what you already know and what you do not.

Step 4: Share the hours out by weight, not by fairness

Now divide your scheduled hours across the topics. Equal slices feel fair and work badly. Use three simple rules instead.

• Weight by exam value. A topic worth a big share of the marks deserves more time than a minor one, and the syllabus or past papers usually show which is which.
• Weight by weakness. Rated-3 topics get roughly twice the time of rated-1 topics.
• Weight by distance. The earliest exam gets its hours first. Do not give a subject that is five weeks away the evenings you need for the one that is next week.

Write the hours next to each topic. If the total is larger than your scheduled hours, do not squeeze. Cut the lowest-value, strongest topics down to a single review slot, and accept that you will not cover everything at the same depth. Choosing what to leave thin is part of the plan, not a failure of it.

Step 5: Build the weekly grid

Now place the sessions. Use a simple grid with days across the top and three blocks per day (morning, afternoon, evening), and fill it in this order.

• Fixed commitments first. Lessons, work, training and meals.
• Hardest topics in your best hours. If you think best in the morning, put the rated-3 topics there.
• Shorter sessions. Aim for 25 to 50 minutes of work followed by a break. Our guide to the Pomodoro technique shows settings that work for revision.
• Alternate subjects. Two hours of one subject in a row feels efficient, but changing subject between blocks keeps you fresher and helps memory.
• A short review at the start of each session. Spend the first five minutes recalling what you studied last time, from memory. That is the spaced repetition built into the plan.
• Rest. One half-day and one full evening off each week. They are not a reward; they are part of how the study sticks.

Keep the labels specific. "Chemistry: acids and bases, practice questions" tells you what to open and what to do. "Study chemistry" tells you nothing.

Step 6: Put catch-up time and mock exams on the plan

Two things belong in the timetable from the start, and most plans leave them out.

The first is catch-up. Keep one slot per week, such as Saturday afternoon or Sunday morning, that is empty. When a session is missed, it moves there. If you do not need it, you have a free afternoon, and that is a good problem to have.

The second is practice under exam conditions. In the last third of your time, replace some study sessions with timed past papers or practice questions, and book the time to mark them. Our guide to checking your own answers explains how to turn each mark you lost into the next thing to study. If the clock is tight, our plan for revising for an exam in a week shows what to cut first.

Doing it with Orbily

A timetable only works if the sessions inside it actually happen. Orbily's Study Timer helps with that part: you pick a duration or go open-ended, choose your subject and study inside a calm progress ring, and every minute counts toward your revision time and streak. It does not write your plan for you, and it will not decide what you study. You still build the timetable and choose what goes in each block. You can read more about the Study Timer.

A worked example: four weeks, three exams

Say today is 1 May. You have biology on 28 May, history on 30 May and maths on 3 June. Here is how the method plays out in about 20 minutes.

• Count the days: biology is 4 weeks away, history 4 weeks and 2 days, maths a little over 5 weeks.
• Find your hours: after school, meals and training you have about 3 usable hours on weekdays and 5 at weekends. That is 25 hours a week, and you schedule 18.
• List topics: biology has 9, history has 7, maths has 10. You rate each one, and find 4 rated 3: two in biology, one in history, one in maths.
• Share the hours: biology gets the most because it comes first and has two weak topics. Maths comes last, so it gets less early on but more in week four.
• Build the grid: weekday evenings are 45 minutes of each of two subjects, weekends have one longer session on a rated-3 topic and one timed practice paper in the last two weeks.
• Keep Sunday afternoon empty for catch-up, and one evening a week off.

The result is a single page, one table, and a plan with room to breathe.

Common mistakes to avoid

• Scheduling every hour. A full plan has no slack, so the first sick day breaks it.
• Planning by subject. A block called "maths" does not tell you what to open. Plan by topic.
• Making it beautiful and never using it. Colour is fine, but if the planning takes longer than an evening, you are procrastinating with stationery.
• Giving every subject equal time. Spend more on what is weak and heavily marked.
• Leaving out reviews. Without a short recall at the start of each session, last week's work fades before the exam.
• Never changing it. A timetable is a first draft. Look at it every Sunday and move things that did not work.

Check it every week

Take ten minutes each Sunday to look at what you did against what you planned. Tick what is done, move what is not, and re-rate the topics you have been working on. If a rated-3 topic is now a 2, shift its hours to one that still needs help. If you are behind, remove something rather than cramming. A plan you change every week is a plan you are still using.

Final thoughts

A revision timetable is not a promise; it is a map you adjust as you go. Work backwards from the exam dates, count the hours you really have, plan by topic, give the most time to what is weak and valuable, and leave space for catch-up, practice papers and rest. Then look at it every week and change it without guilt. That plan will do more for you than a perfect-looking one that nobody can follow.
