Every exam season produces the same artifact: a gorgeous, color-coded revision timetable, built in a two-hour burst of virtue, abandoned by Thursday. It fails for a predictable reason — it was a drawing, not a calculation. It didn't know which subjects were shaky, didn't rebalance when a mock went badly, and treated the exam three days away the same as the one in June. This builder is the calculation: three inputs, and the agonizing about what to revise today is done by arithmetic instead of mood.

Three inputs, one honest number

The exams. Subject and date, however many papers you're facing.

Your confidence, honestly. Each exam gets a rating — shaky, okay, solid. This is the input that makes the timetable yours instead of generic, and honesty pays directly: shaky subjects get more sessions, so flattering yourself literally steals revision time from where it's needed. (Optimism here is common and well-documented — people underestimate what work needs even with their own track record in full view.)

Your real pace. How many revision sessions actually fit a day of your life — one to four. A timetable that assumes eight is a resignation letter to yourself, pre-signed. Three honest sessions kept daily beat a heroic Sunday that poisons the week.

Generate, and every day from now to your final exam gets its sessions: closer exams and weaker subjects weighted heavier, every subject spaced across the calendar, exam days marked in the grid with their countdown. Change anything — a date, a rating, the pace — and the plan rebalances instantly.

The shuffle is the strategy

The generated grid will look suspiciously mixed — history Tuesday, maths Wednesday, history again Friday — and the temptation is to "fix" it into tidy single-subject blocks. Don't. Spacing study across separated sessions is the most robust finding in the learning literature: distributed practice beats massed practice for retention, over and over, across ages and materials. Same hours, more kept. The builder spaces by design, and the slight discomfort of switching subjects is the feature working.

What you do inside each slot matters just as much: close the notes and test yourself. Retrieval practice beats rereading in head-to-head studies — even though rereading feels smoother, which is exactly why it fools people. Past papers, flashcards, blank-page recall: the timetable names the subject, self-testing should be the default verb.

Tick, adjust, repeat

Today's row sits highlighted at the top of the grid. Revise a session, tick it — the tick is the tiny reward that keeps the streak honest. After a mock or a practice paper, re-rate the subject: one tap on the confidence chip and the remaining weeks redistribute around the new truth. The timetable isn't a contract with your past self; it's a live model of the situation, and updating it is using it well.

The rest of the exam kit

The timetable allocates the days; its neighbors handle the rest. Big dates and coursework deadlines live on the semester deadline tracker — that's the what's due view, where this is the what to study view. Individual sessions run well as tomatoes in the pomodoro planning worksheet, day-to-day homework keeps flowing through the homework planner, and if exam nerves start writing the schedule instead of you, sixty seconds of box breathing before a session is the cheapest focus aid there is.

Enter the exams. Rate them honestly. Let the arithmetic carry the worry — you just show up for today's row.
