Plenty of revision timetables are abandoned within a week or two, usually for the same few reasons. They assume more free time than exists, with eight hours of revision penciled into a day that also has classes and a part-time shift. Their slots are vague, so “History, 2 to 4 pm” gets spent deciding what to do. They are ordered by preference, so favorite subjects get the best hours. And they have no slack, so one missed evening throws off the whole week and the plan starts to feel like a record of failure.
A timetable you will stick to fixes each of these on purpose. It starts from real hours, names a concrete task for every slot, weights time by need rather than taste, and leaves room for things to go wrong. It also changes as you go, because every week of revision tells you more about where your weak spots are.
Before you draw any grid, gather three lists. The first is your exams: each subject, its date and how long until it. The second is every topic in every subject, taken from the official syllabus or course outline rather than from memory, because memory leaves out exactly the topics you have forgotten. The third is your week as it really is: classes, work, travel, meals, sleep, exercise and anything else that is fixed.
Next, rate each topic red, amber or green. Red means you could not answer an exam question on it today, amber means you could answer part of one, and green means you are confident. Be honest, since these ratings decide where your time goes. Finally, count the hours left in your week once the fixed commitments are blocked out, then take off a few more for rest. A timetable that uses every free minute will not survive its first bad day.
With the audit done, building the timetable takes about an hour. Plan the next two weeks in detail and the rest of the period in outline, because your ratings will change as you revise. Step seven keeps each subject coming back across the week, and step eight builds in spaced repetition, which keeps early topics from fading by exam week. Within a subject, mixing problem types, known as interleaving, also trains you to choose the right method.
Here is an example week for a student with exams in biology, history and math about six weeks away, and classes on weekdays. Every slot is a task, each day mixes subjects, red topics such as integration appear more than once, and Sunday holds the buffer and the weekly review.
| Day | Block 1 | Block 2 | Block 3 |
|---|---|---|---|
| Monday | Biology: draw the stages of mitosis from memory, then check | Math: eight differentiation problems, marked | Free |
| Tuesday | History: list the causes of the First World War from memory, then check notes | Biology: enzyme flashcards, then two exam questions | Free |
| Wednesday | Math: five integration problems | History: timeline of 1914 to 1918 from memory | Biology: redraw Monday's mitosis diagram |
| Thursday | Biology: respiration questions from a past paper | Math: redo Monday's differentiation mistakes | Free |
| Friday | History: one essay plan in 20 minutes | Biology: explain enzymes aloud, then check notes | Free |
| Saturday | Math: mixed differentiation and integration set | History: source analysis practice question | Biology: two past-paper questions |
| Sunday | Buffer: catch up on anything missed | Weekly review: re-rate topics, plan next week | Free |
One of the most useful changes you can make to a revision timetable is replacing subject names with tasks. A slot that says “Biology” has to be turned into a decision when it arrives, and that decision is where procrastination starts. A slot that says “Biology: answer two past-paper questions on photosynthesis and mark them” can be started at once, and you know when it is done.
Good tasks are active: they involve answering, drawing, explaining or solving, not reading or going over. They are sized to fit the block. And they produce something you can check, which also leaves a record of what you actually did. Some examples of the difference:
Following a timetable is a habit, and habits form faster when they are attached to things you already do. Start each day's first block at a fixed time tied to an existing routine, such as straight after breakfast or as soon as you get home. Keep the first few days light, so the plan starts with success rather than strain.
Track what you actually do with a tick against each completed block. At the end of the week, take twenty minutes to re-rate your topics and plan the next week in detail. If you missed a block, move its task to the buffer slot rather than squeezing it into an already full day. If you keep missing the same block, it is in the wrong place, so move it instead of just trying harder.
As exams get closer, shift the balance from learning to testing: fewer new topics, more timed questions and full past papers marked strictly. In the last two weeks, a two-week plan for finals shows how to lay out those final days, past papers included.
A Cavua course gives your timetable ready-made units: each course is organized into chapters and lessons, and every lesson and chapter has a test whose result is saved. Those results work as a confidence rating you do not have to guess, showing which chapters are red and belong in the early weeks. When a block stalls on something you do not understand, the course's 24/7 AI tutor answers from that course's own syllabus and lessons, by chat, voice call or video call, so the block is not lost.
For school or university subjects, you can upload your own notes and handouts to the Work space and use “Quiz me” as the task in a revision slot. The AI tutor page explains how the course tutor works.

Cornell notes split each page into notes, cue questions and a summary, so your notes double as a self-test. How to set up the page, take notes and review them.

How to finish an online course you started: choose the right course, set a finish date, book short sessions, get unstuck fast and restart after a missed week.
How to focus while studying: set up a distraction-proof space, define one concrete task, work in timed blocks, and get your mind back when it wanders.
How to stop procrastinating on study: why you put it off, how to start in ten minutes, if-then plans, fewer distractions, and handling the feelings behind it.
There is no single right number; it depends on how many subjects you have, how close the exams are and what else fills your day. Focused blocks with real rest between them beat long, unfocused days. During study leave, four to six hours of genuine revision is a full, demanding day for most people, and on days with classes, one or two blocks is a solid contribution.
Ideally six to eight weeks before your first exam, which leaves time to cover every topic and return to the weak ones more than once. Starting later is still worth it: plan fewer topics per week, put red topics and past papers first, and accept that some green topics will get a single pass. A timetable started three weeks out is far better than none.
Mixing usually works better. Two or three subjects in a day keeps sessions fresher, and coming back to a subject after a gap gives you spaced review. Mixing different types of problem within a subject, known as interleaving, also trains you to choose the right method. Keep each block on one subject, though, so you are not switching every few minutes.
Do not try to make up everything at once. Use your buffer slot for the most important missed tasks, shorten or drop lower-priority green topics, and re-plan the next week from where you actually are. Falling behind is normal; the timetable exists to help you make good decisions about your time, not to keep score of what you missed.
A template can save time on layout, but a timetable's value is in its contents: your real hours, your topics and your confidence ratings. A simple grid of days and blocks on paper or in a spreadsheet is enough. Whatever you use, make sure each slot has room for a specific task rather than just a subject name, because that is what gets you started.
Start the audit with your fixed commitments and plan only the gaps that are reliably yours, even if they are short. Two 40-minute blocks on weekday evenings and two longer blocks at the weekend add up over six weeks. Use short gaps, such as a commute or a lunch break, for flashcards or recall from notes, and keep the longer blocks for practice questions.
Every Cavua course comes with a 24/7 tutor you can video call, speak to or chat with — on the material you are actually studying.
