Exam Countdown & Study Planner
Count the days to your exam and turn them into a realistic per-subject study plan.
"Thirty days to go" is not a plan. This tool converts the days left into usable study hours after removing the days you will not study, reserves time for revision, and divides what remains across your subjects — so you know whether the schedule is realistic before you build it.

What the Exam Countdown & Study Planner does
Most study plans fail for the same two reasons: they assume every remaining day is a study day, and they leave no time for revision. Both are optimistic in ways that only become visible in the final week.
This planner subtracts the days you know you will lose, holds back a share of the total for revision, and reports hours per subject. If that number looks too small, you have found out early enough to prioritise rather than late enough to panic.
How to use this tool
- Enter the date of your first exam.
- Enter how many subjects you need to prepare.
- Set the study hours you can genuinely sustain per day — not your best day, your average one.
- Add the days you will lose to travel, festivals, family commitments and illness.
- Set the share of time reserved for revision. Twenty-five percent is a reasonable default.
- Check the hours-per-subject figure. If it is under about ten, plan by topic weightage instead of full coverage.
Formula and method
Study days = Days until exam − Days you cannot study
Total hours = Study days × Hours per day
Revision hours = Total hours × Revision share
Learning hours = Total hours − Revision hours
Hours per subject = Learning hours ÷ Number of subjects
Days are counted from today to the exam date, excluding the exam day itself. The week-by-week plan switches from new material to revision at the point your revision share begins.
Worked example
Example: 40 days to go, 5 subjects, 5 hours a day
| Days remaining | 40 |
| Less days off | 4 → 36 study days |
| Total hours | 180 |
| Revision (25%) | 45 hours |
| Per subject for new material | 27 hours |
Twenty-seven hours per subject is roughly five and a half working days each. That is enough for solid coverage of a standard semester paper, but not for starting from zero in all five.
What your result means
Hours per subject is the number that tells you whether the plan is feasible. Under 10 hours means selective preparation; 20–40 is comfortable for a semester paper; over 60 suggests you can afford depth.
Revision hours are not spare capacity. Recall practice and past papers consistently outperform re-reading, and cutting revision to cover more syllabus is the most common planning mistake.
The week-by-week table gives the shape of the schedule: new material first, then a transition week, then revision and past papers.
Important considerations
- Subjects are not equal. Weight your time by credits and by how much of the syllabus you already know rather than dividing evenly.
- Past papers are worth more per hour than notes in the final two weeks. Reserve time for at least two full timed attempts per subject.
- The gaps between papers are useful for revision, not for learning new topics. Plan to arrive at the first exam already prepared for the last.
- Sleep is part of the plan. Consistent shorter days beat a few very long ones followed by a collapse.
- If the numbers show the syllabus cannot be covered, decide what to drop deliberately rather than running out of time and dropping it by accident.
Limitations of this tool
- It assumes uniform hours per day and equal time per subject. Adjust the split yourself once you see the totals.
- It counts from today to your first exam only. If your papers are spread over three weeks, the later ones have more time than this shows.
- It cannot judge how much you already know, which is the single biggest factor in how much time each subject actually needs.
Frequently asked questions
How many hours a day should I study before exams?
Four to six focused hours is sustainable for most students over several weeks. Twelve-hour days work for a few days and then collapse. Consistency across the full period produces more than intensity in bursts.
How much time should I keep for revision?
Around 25% of the total is a reasonable default, rising to a third if the syllabus is memory-heavy. Revision through recall and past papers is more effective per hour than first-time reading.
Should I study one subject at a time or rotate?
Rotating between two or three subjects usually produces better retention than blocking one subject for days, though blocking is more efficient when you are learning something entirely new.
What if I have only a week left?
Stop trying to cover the syllabus. Work from past papers, focus on the highest-weightage topics, and make sure you can attempt every section rather than perfecting a few.
