Example Data Table
Use this sample structure if you want quick test inputs.
| Subject | Target Hours | Completed Hours | Difficulty | Priority | Confidence | Exam Date |
|---|---|---|---|---|---|---|
| Maths | 18 | 2 | 5 | 4 | 2 | 2026-03-09 |
| Physics | 14 | 1 | 4 | 5 | 3 | 2026-03-11 |
| Chemistry | 16 | 0 | 4 | 4 | 3 | 2026-03-14 |
| English | 8 | 1 | 2 | 2 | 4 | 2026-03-17 |
Formula Used
1) Remaining subject time
Remaining Minutes = max((Target Hours − Completed Hours) × 60, 0)
2) Daily usable capacity
Usable Minutes = Daily Focus Minutes × (1 − Buffer %)
3) Daily review split
Review Minutes = Usable Minutes × Review %
Study Allocation Pool = Usable Minutes − Review Minutes
4) Subject weighting score
Weight Score = Remaining Minutes × Base Factor × Urgency
Base Factor = (0.40 × Priority) + (0.35 × Difficulty) + (0.25 × (6 − Confidence))
5) Session building
The generator fills each day with timed sessions using your session length, short/long breaks, and max sessions per day. Earlier exams get higher urgency.
How to Use This Calculator
- Enter your plan dates, daily study hours, and preferred start time.
- Set session length, short break, long break interval, and max sessions.
- Choose buffer and review percentages to protect realistic planning time.
- Add subjects with target hours, completed hours, difficulty, priority, confidence, and exam dates.
- Click Generate Revision Timetable to create the schedule above the form.
- Use Download CSV or Download PDF to export the timetable.
- Adjust hours or end date if any subject shows unscheduled time.
Revision Capacity Planning
Start with realistic capacity, not idealized study hours. Students overestimate availability by ignoring travel, meals, schoolwork, and fatigue. This calculator improves planning by splitting weekday and weekend capacity, then reserving buffer and review time. A 10% buffer absorbs delays, while dedicated review minutes reduce forgetting. In practice, this structure creates steadier output than aggressive plans that collapse after two or three difficult days.
Priority and Difficulty Weighting
Not every subject should receive equal attention. The weighting model combines priority, difficulty, and confidence to estimate where each new study session creates the highest return. Hard subjects with low confidence and near exams receive more minutes automatically. Easier subjects still stay in the plan, but they consume less of the allocation pool. This prevents common revision errors such as overstudying favorite topics and neglecting weak, high-risk areas.
Session Design and Break Economics
Long revision blocks look productive but often reduce retention. The generator uses session length, short breaks, and periodic long breaks to preserve attention quality across the day. For example, fifty-minute sessions with ten-minute breaks and a longer break after every third session can sustain concentration without mental fatigue. The max-sessions setting also limits overload. Together, these controls convert available hours into repeatable study cycles rather than one-time bursts.
Exam Urgency and Daily Sequencing
Exam dates matter because urgency changes every day. The timetable increases emphasis on subjects with closer exams, then places sessions into daily slots starting from your preferred start time. This sequencing supports practical execution: students can print the plan, follow the time blocks, and track completion. When a subject has remaining unscheduled minutes, the summary highlights the shortfall, signaling that more days, more hours, or lower targets are needed.
Using Results for Weekly Adjustments
A revision timetable should be updated regularly, not written once and ignored. At the end of each week, enter completed hours again, then regenerate the plan. The next schedule reflects actual progress, revised confidence, and approaching exams. This rolling approach keeps the timetable accurate and reduces guilt from missed sessions. It also improves decision quality because the plan responds to evidence, not assumptions, while maintaining review, recovery, and exam readiness.
FAQs
1) What does the generator optimize first?
It prioritizes subjects using remaining hours, difficulty, priority, confidence, and exam urgency. This helps high-risk topics get earlier and larger allocations while keeping every subject visible in the study plan.
2) Why should I add buffer time?
Buffer time protects your plan from delays, tired days, and interruptions. Without it, timetables look full on paper but become difficult to follow consistently.
3) Can I use different weekday and weekend hours?
Yes. The calculator separates weekday and weekend study capacity, so your timetable matches real routines like school days, coaching classes, or longer weekend revision blocks.
4) How often should I regenerate the timetable?
A weekly update works best. Re-enter completed hours and confidence scores, then generate a new timetable to reflect progress and upcoming exams.
5) What if some subject minutes remain unscheduled?
That means your current date range or daily hours are not enough. Extend the plan, add more study time, reduce targets, or lower review and buffer percentages carefully.
6) Do exports include the generated timetable only?
Yes. CSV and PDF exports capture the generated schedule table so you can print it, share it, or track progress outside the page.
