Study plan calculator: the plain arithmetic
Exam date, weekly hours and syllabus position in; the numbers nobody wants but everybody needs out: total hours left, per-subject weekly time, and the date learning must end.

The arithmetic
This is the static arithmetic behind a plan; a real plan also sequences chapters, adapts to your pace and chases weak areas. That is what the PrepWise planner does daily.
Why this arithmetic changes decisions
Most preparation plans are written forwards: a list of chapters and good intentions. The calculator forces the backwards version: the exam date fixes the total hours, the revision share protects the final phase, and what remains is the learning budget, divisible by subjects and weeks into numbers small enough to be upfront about. Two findings surprise almost everyone who runs it: how much of the remaining time the protected phase consumes, and how few weekly hours each subject actually gets once the week is split. Both surprises are cheaper today than in the final month.
The learning-must-end date is the single number worth writing on a wall. Every week of learning that slips past it is a week stolen from revision and mocks, the phases that convert coverage into marks. Guides on building the timetable itself and deciding daily hours are in the PrepWise guides.
A worked example
An aspirant 30 weeks out, 24 real weekly hours, three subjects, 20% syllabus done, a quarter protected: total budget 720 hours, 180 protected for revision and mocks, 540 for learning the remaining 80%. That is 540 across three subjects, six hours per subject per week, and learning must end around week 22. Suddenly the debate about which reference book to add answers itself: there are six hours a week, and they belong to the syllabus.
Illustrative; run your own numbers above. The planner turns them into an actual daily schedule.
Frequently asked questions
How many hours a day should I study for my exam?
Work backwards, not forwards: hours available until your exam date, split across syllabus remaining, revision and mocks, is the only straight answer, and it differs per person. The calculator does that arithmetic for your date and your week; generic daily-hour prescriptions ignore both.
How much time should revision and mocks get?
A sound default is roughly a quarter of remaining time for dedicated revision and mock cycles, protected at the end, with lighter revision interleaved throughout. The calculator shows the date learning must finish for that protection to survive; crossing it is how final months become rescue operations.
What if the calculator says my syllabus doesn't fit?
Then you have learned it in time to act: raise the weekly hours, triage the syllabus by weightage, or reconsider the attempt window. An impossible plan discovered today is a strategy question; discovered in the final month it is only a regret.
