Check Whether You Actually Have Time To Revise
A revision plan fails on hours, not effort. This adds up the hours each topic genuinely needs, works out how many hours you actually have after subtracting the days you won't study, and prints the difference per day. If the numbers don't fit, the worksheet says so in week one — which is when there's still something you can do about it. Local only; nothing leaves the tab.

The workflow
Estimate hours by topic, not by subject
'Biology' is not estimable; 'cell signalling, 4 hours' is. Breaking a subject into topics is what makes the total honest, and it usually reveals that one or two topics dominate the whole budget.
Subtract the days you won't study
Work shifts, family commitments, and the days you know you won't manage. Most people overstate their available days by a third, and the worksheet is only as useful as this subtraction.
Use a daily capacity you can sustain
Four focused hours beats eight planned hours that collapse by day three. Enter the number you'd defend on your worst day, not your best — the deficit it produces is the real one.
Cut topics on purpose if there's a deficit
When the hours don't fit, deciding which topics to drop is a strategy; discovering it during the exam isn't. Cut the lowest-yield topics deliberately and revise the rest properly rather than skimming all of them badly.
Worked example
Sample: 6 topics needing 46 h, 14 days less 4 unavailable Required 46 h Available 10 days × 4 h = 40 h Deficit 6 h (15% over) Needed per day 4.6 h against a 4 h capacity Uploaded nothing — computed in the tab
Numbers above are sample data produced by the tool's own pre-loaded example, run in the browser — not averages or measured benchmarks.
What breaks this
Estimating by subject rather than topic produces a total nobody can act on. Counting every day as available overstates capacity by a third or more. Setting daily capacity at your best day makes the plan collapse on the third.
Try it now
Six topics needing 46 hours against 40 available are loaded, a 6-hour deficit. Raise the daily capacity to 5 and watch it flip to a margin.
