Study Revision Planner Calculator

Turn deadlines into calm, achievable revision sessions. Balance subjects, breaks, and practice with clear timers. Stay consistent, see progress, and finish exams confidently always.

Planner inputs

Before breaks. Planner applies break percentage.
Flashcards, recall drills, and spaced review.
Reduces focus hours to keep plan realistic.
Adds time for revision and recall around core learning.
Reserves end-of-plan days for mocks and weak areas.
Ramp gradually increases effective hours over time.
Lower values reduce context switching.
Smaller blocks help when time is tight.
Intervals are days after finishing core content.
Uncheck days you cannot study. Planner will skip them.

Use estimates that match your syllabus scope. Raise mastery if you already know the basics.

Formula used

  • Core remaining hours = EstimatedHours × (1 − Mastery%/100)
  • Required focus hours = CoreRemaining × (1 + RevisionOverhead%/100)
  • Day focus hours = DayHours × (1 − Break%/100) − ReviewMinutes/60
  • Subject weight = RequiredFocusHours × Priority × Difficulty
  • Plan scaling: If total work focus hours < total required, the plan scales down proportionally.
  • Revision dates: After core completion, add spaced intervals (e.g., 1,3,7,14 days) and snap to the next study day.

How to use this calculator

  1. Set your start date and exam date.
  2. Choose realistic daily hours, breaks, and review minutes.
  3. Select the weekdays you can consistently study.
  4. Add subjects with estimated hours, priority, difficulty, and mastery.
  5. Submit to generate your daily schedule and revision roadmap.
  6. Download CSV for spreadsheets or PDF for printing.

Planning window and capacity

Compare calendar days to available study days. With 3.0 hours per study day, 10% breaks, and 20 minutes of review, the calculator yields 2.50 focus hours and 0.33 review hours per study day. Multiply focus hours by work days to estimate usable learning time. A 30‑day window with 5 study days per week gives about 21 study days, or roughly 52.5 focus hours. Ramp mode can gradually lift these hours near the deadline. This clarifies daily capacity quickly.

Subject weighting and hour allocation

Subjects are adjusted using mastery, priority, and difficulty. Core remaining hours equal EstimatedHours × (1 − Mastery%). If mastery is 70%, only 30% of estimated hours remain. Required focus hours add revision overhead, so 30 core hours with 25% overhead becomes 37.5 focus hours. Allocation uses SubjectWeight = RequiredFocusHours × Priority × Difficulty, pushing demanding topics earlier. If available focus hours are lower than required, planned hours scale down proportionally to keep the schedule achievable.

Daily schedule blocks and switching control

To reduce context switching, the planner limits subjects per day and enforces a minimum block length. With a 2‑subject limit and 1.0 hour minimum blocks, a 2.50 focus‑hour day becomes two blocks (1.25h + 1.25h) or a 1.50h block plus a 1.00h block. If you choose 3 subjects per day, the same time splits thinner. Remaining minutes default to practice or past papers, keeping effort measurable.

Spaced revision roadmap

After core completion, revision sessions follow spaced intervals such as 1, 3, 7, and 14 days. If a target date is not a selected study weekday, it snaps forward to the next available study day. Daily review minutes provide baseline retrieval practice, while interval revisions act as deeper consolidation checkpoints. Custom intervals help match your course pace and memory strength.

Buffers, exports, and execution tracking

Buffer days are reserved at the end based on the buffer percentage. A 10% buffer on 21 study days reserves about 2 days for mocks, weak‑area recovery, and rest. Buffers also protect the plan when real life steals a session. Use CSV export to log completion, track actual time spent, and calculate variance per subject. Use PDF export for printing. Re‑run weekly and update mastery so allocations adapt as performance improves.

How should I estimate subject hours?

List chapters, past papers, and practice sets, then estimate sessions and minutes per session. Start conservative. As you improve, raise mastery to reduce remaining hours instead of rewriting the whole plan.

What does mastery percentage represent?

It is your current readiness for that subject’s syllabus. 0% means new content, 100% means exam-ready. The planner reduces remaining core hours using mastery, so update it weekly using timed quizzes and error logs.

Why reserve buffer days?

Buffers absorb missed sessions, fatigue, and unexpected school events. They also provide space for mock exams and mistake review. If buffers stay unused, convert them into extra practice blocks and recovery rest.

How are revision dates selected?

After core completion, the planner adds your spaced intervals (for example 1, 3, 7, 14 days). If the target lands on a non-study day, it shifts to the next selected study day.

What should I do if the plan is tight?

Increase daily hours, add more study weekdays, reduce buffer percentage, or trim low‑impact topics. Keep fewer subjects per day to protect focus, and use practice blocks to strengthen weak areas quickly.

Can I use the CSV in spreadsheets?

Yes. Import the CSV into Excel or Google Sheets, then add columns for completion, actual hours, and notes. Compare planned versus actual weekly to spot overload, adjust mastery, and rebalance upcoming blocks.
