How to Make a 30-Day Revision Timetable You'll Actually Follow

Quick answer: Build a 30-day revision timetable out of blocks, not fixed clock times. Count your honest available hours, split them 40 percent weak topics, 40 percent past-paper practice and 20 percent review, then leave one empty catch-up day every week. A plan with slack survives a bad day; a rigid hour-by-hour grid collapses the first time you miss it.

I made my first proper timetable in Year 10, before my Cambridge IGCSE mocks. Colour-coded spreadsheet, every hour from 4pm to 9pm filled. I lasted three days. On the Thursday I missed one chemistry hour, Friday was already full, and by Sunday I was four hours behind a plan built for someone who never gets tired. What follows is what I use now. It expects me to fail some days.

Step 1: Audit your real hours before you name a single subject

Work out how many hours you genuinely have, not how many you wish you had. Split the 30 days into three kinds:

• Study days — school, then revision after. Be honest: for most people that is 2 focused hours, not 5.
• Long days — weekends, holidays, study leave. Four hours is realistic; eight is a fantasy you pay for on Monday.
• Catch-up and rest days — one of each per week, booked in advance with nothing on them.

A normal month gives roughly 20 study days, 4 catch-up days, 4 rest days and 2 spare. If study days average 3 hours once you blend school nights with weekends, that is 60 usable hours. Sixty is the whole budget.

Step 2: Rank topics by damage, not by dread

Score every topic twice, then multiply. Most of us revise what feels frightening or what feels comfortable, and neither is what actually costs marks.

For each topic on your specification:

• A frequency score, 1 to 3 — how often it appears in the last four past papers.
• A confidence score, 1 to 3 — how well you would do on it cold, no notes.

Priority = frequency x (4 minus confidence).

Worked through for IGCSE chemistry: electrolysis appears in 3 of the last 4 papers and you would score 1 out of 3 cold, so priority = 3 x 3 = 9. Balancing equations appears in all 4 papers but you are solid: 3 x (4 - 3) = 3. Simple distillation appears once and you are shaky: 1 x 3 = 3.

Electrolysis therefore earns three times the blocks of the other two, even though balancing equations is the more common topic. Sort by that number and you have a queue instead of a mood.

Step 3: Turn hours into blocks, then split them 40/40/20

Sixty hours across four subjects is 15 hours each, which in 45-minute blocks is 20 blocks per subject. Written that way the month stops feeling infinite: 20 attempts each, and you know what to spend them on.

Split each subject's 20 blocks:

• 8 blocks (40 percent) on top-priority topics from step 2
• 8 blocks (40 percent) on past-paper questions and exam technique
• 4 blocks (20 percent) on spaced review of things you know now but will forget

That last 20 percent is the first thing everyone deletes, and it is why students who revised everything still go blank in the hall.

Step 4: What goes inside one 45-minute block

Every block should end with evidence you can point at.

1. 5 minutes, closed-book recall. Everything you remember from your last block on this subject. No notes. Embarrassing on day one, fine by day nine.
2. 25 minutes, the actual topic. Notes, worked examples, a video, whatever it needs.
3. 10 minutes, one exam question, timed. Not reading the answer. Writing it.
4. 5 minutes, the wrong book. One line per mistake, in your own words, correction beside it.

Those last 5 minutes are where the marks live. By week 3 the wrong book is your only revision resource that is genuinely personal, and it is ideal material for flashcards — every card is something you have proved you get wrong.

Step 5: The 30-day map, week by week

The ratio of learning to practising should invert across the month.

Days 1 to 7 — 60 percent relearn, 40 percent practice. Day 1 is the diagnostic: one past-paper section per subject, untimed, marked honestly. It stings, and it makes step 2 accurate instead of guesswork. Then spend the week on your top two topics per subject.

Days 8 to 14 — an even split. Work down the priority list, add one timed section per subject, and re-test your day-1 topics from memory. Anything still weak jumps back up the queue.

Days 15 to 21 — 30 percent relearn, 70 percent practice. One full past paper per subject, timed, then self-marked against the official mark scheme. Marking your own script with the scheme open teaches you the wording examiners reward: the "because" clause in biology, or the sentence that turns a history paragraph from description into explanation.

Days 22 to 28 — almost entirely practice. Revisit a topic only if a paper proves you still cannot do it. Rewrite your three worst answers in full.

Days 29 to 30 — taper. Read the wrong book. Nothing new goes in this late; it will not stick and it will scare you.

Step 6: Where AI helps, and where it only feels like work

AI is good at generating practice and bad at knowing your life. Use it only for the first.

• The quiz tool makes practice questions from material you give it. Paste in the chapter or your notes at the end of a block, then answer closed-book.
• The mock exam tool generates a full practice paper in your board's style. One per subject in weeks 3 and 4, properly timed, beats a week of highlighting.
• The grader gives feedback on written answers, which matters most in essay subjects where you cannot mark yourself objectively.

What it cannot do is know your specification or how wrecked you are on Wednesdays. Pull the spec from your board directly — AQA, Edexcel and OCR for GCSE, or Cambridge, CBSE, AP and WAEC — and do the hour audit yourself.

Building the timetable is also not revision. Give it 40 minutes, once. If you are still colour-coding on day two, that is procrastination wearing a lanyard.

Step 7: The missed-day rule that keeps the plan alive

When you miss blocks, move them sideways into that week's catch-up day, never forward onto tomorrow. Tomorrow is already full, and that is how a two-block slip becomes a six-block deficit by Sunday.

If you fall more than one catch-up day behind, stop trying to reclaim it. Delete the lowest-priority blocks instead, anything scoring 3 or below. A plan finished 85 percent complete beats a perfect plan you quit on day 11. Mine has never hit 100 percent, and my grades did not notice.

Test yourself

1. You have 20 blocks for biology. Using the 40/40/20 split, how many go to past-paper practice?
2. Topic A appears in 3 of the last 4 papers, confidence 3 out of 3. Topic B appears in 2, confidence 1 out of 3. Which comes first, and why?
3. You lose two blocks on Wednesday. Where do they go?

Answers: 8 blocks; Topic B, scoring 6 against Topic A's 3; into this week's catch-up day, not Thursday.

FAQ

How many hours a day should a 30-day revision timetable have?

Two focused hours on a school day and around four on a free day is a realistic ceiling. Beyond that you are logging hours, not learning. Judge a day by blocks completed, not time served.

Is 30 days really enough to revise for a full exam?

For a single subject, usually yes, provided you go straight at past papers and your weakest high-frequency topics. It is not enough to learn a two-year course from nothing, which is why people who spend week one re-reading chapter 1 run out of days.

Can AI just build my whole revision timetable for me?

No. Anything claiming to is guessing at your hours, your specification and your weak spots. AI is strong once you have told it what to focus on, and useless before that.

What if I take seven subjects rather than four?

Same method, smaller budget each. Sixty hours across seven subjects is roughly 8.5 hours, or 11 blocks each, so the split becomes 4 on weak topics, 4 on past papers and 3 on review. Tight, which is why the ranking matters more, not less.

In short

Count your honest hours, rank topics by frequency times lack of confidence, convert the total into 45-minute blocks split 40/40/20, and invert the learn-to-practise ratio across the four weeks. Leave one empty day a week so a bad Wednesday cannot kill the plan. The timetable that works is the boring one you are allowed to miss.
