What this result does not account for
- Even subject split as a starting pass — re-weight by weak papers
- Calendar-day lane only — syllabus size lives on the pace page
In short: 45 days at 3 hours a day is a 135.000000-hour budget — 21.000000 hours a week, shared across six subjects as 3.500000 hours each per week. The countdown is arithmetic about your calendar, not your willpower: days times daily hours sets the whole envelope, and every plan that ignores the division fails the multiplication later. Study-skills guidance lands in the same band — one to two hours a day months out, three to four in the final weeks.
Formula
budget = days × hours/day ··· weekly = budget × 7 ÷ days ··· per subject = budget ÷ subjects
A countdown is a budget: multiply the days you have by the hours a day you will actually keep, and treat the product as the whole envelope. Spreading it across subjects divides evenly only as a first pass — weight the weaker papers heavier in practice. The rhythm matters more than the total: revision guidance for GCSE and A-level cohorts runs one to two hours a day early, two to three mid-season, three to four in the final weeks, with a rest day a week — marathons borrow from tomorrow's retention. What the budget cannot say is whether it is enough; that is the syllabus's question, priced on the Learning Pace page.
Worked Example
- Count the calendar days to the paper.
- Commit to sustainable daily hours.
- Read the budget in hours and per week.
- Split it across the subjects.
Defaults: 45 days × 3 h → 135.000000 hours, 21.000000 a week, 3.500000 per subject per week across six papers. Drive the days to 14 → the same 3-hour habit funds only 42.000000 hours — 7.000000 a week, 1.750000 per subject: the countdown exists to make that trade visible before the calendar does.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Exam Countdown Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How many hours a day should I revise?
Study-skills guidance for GCSE and A-level cohorts lands on one to two hours a day when exams are months out, two to three midway, and three to four in the final weeks; full study leave sustains four to six. Consistency beats heroics — the budget multiplies whatever daily number you can actually keep.
How do I split hours across subjects?
Divide evenly first, then re-weight toward the papers with the most ground to cover — the split here is the neutral starting point, not the finishing move. Revisit after each mock: hours follow the gap, not the comfort.
Is 135 hours enough?
That depends on the syllabus, not the number — a subject you have kept up with needs revision hours; one you are meeting for the first time needs learning hours, which cost far more. Price the units on the Learning Pace page and compare budgets, not vibes.
Should I count today, the exam day, or both?
Count the days that will contain real study. Exam day itself is not a study day, and today usually is — but partial days round down honestly. The page multiplies whatever count you give it; feed it the number you would defend to your calendar.
Do I need a rest day every week?
The revision guides are unanimous enough to quote: at least one full rest day a week, plus unstructured time daily, because retention — not just morale — degrades without recovery. A budget built on seven-day weeks borrows from weeks you will not repay.
What if my daily hours change week to week?
Enter the average you can sustain, or run the page once per phase — a 3-hour month followed by a 4-hour fortnight is two budgets, and two honest runs beat one inflated one. The arithmetic is linear on purpose.
Cramming versus spreading — does the math care?
The budget is identical either way; the retention is not. Spaced schedules beat massed ones for long-term recall, which is why the final weeks' hours work best as review of earlier passes rather than first contact. The Flashcard Study page prices that spacing per card.
What if the exam is tomorrow?
The honest budget is whatever hours remain, and the page will print it small. Triage: past papers, weak topics, sleep before the paper. A one-day budget is real arithmetic, just not a plan you should ever need twice.
