About this calculator
This calculator starts with the number of subjects you are revising and the total hours you would like to spend on each one. It then spreads that workload across the time and study days you have left.
How to use it
- Choose your exam date and number of subjects.
- Estimate how many total revision hours you want to give each subject.
- Choose how many days each week you can study to see your weekly and per-day workload.
How many hours should I study?
There is no single correct number for every student. A useful plan is one that fits the time available and can be repeated consistently. If the suggested daily workload looks unrealistic, reduce the total target hours, start earlier or spread study across more days.
Study hours formula
Total study hours = subjects × target hours per subject
The calculator divides those hours across the weeks and study days remaining before the date you enter.
The result is a planning estimate, not a rule for how much anyone should study. Adjust it for subject difficulty, deadlines, rest, school workload and your own concentration.
