Formula Used
Available Study Hours = Days Left × Study Hours Per Day
Effective Study Hours = Available Study Hours × Focus Efficiency
Topic Load = Total Topics × (Average Difficulty ÷ 3)
Required Hours = Topic Load × 1.7 × Weakness Factor × Retention Factor × Confidence Factor × Cycle Factor
Coverage Ratio = Effective Study Hours ÷ Required Hours
Predicted Score = Mock Score + Coverage Gain + Retention Gain + Confidence Gain
Readiness Score blends mock score, confidence, retention, and coverage into one revision health metric.
This model estimates how your remaining time, weak areas, attention quality, and current performance combine to shape final revision strength.

Frequently Asked Questions
1. What does this calculator estimate?
It estimates how much revision you can realistically finish before the exam. It also predicts readiness, score improvement potential, topic coverage, urgency, and the chance of reaching your target score.
2. Is this useful for any exam type?
Yes. You can use it for school exams, board exams, university tests, entry tests, and certification prep. The logic works best when you enter realistic topic counts, hours, and performance data.
3. What is the readiness score?
The readiness score is a blended indicator. It combines your latest mock result, confidence, retention, and study coverage to show how prepared you appear for the remaining revision window.
4. Why does focus efficiency matter?
Not every planned hour becomes productive learning. Focus efficiency adjusts your total hours to reflect distractions, fatigue, and poor concentration, giving a more practical revision estimate.
5. How should I set weak topics count?
Count the topics you still avoid, forget often, or score poorly on in practice. Weak topics increase required revision time because they usually need slower review and repeated recall.
6. What if my predicted score is below target?
You should reduce low-value tasks and reallocate time to weak topics, active recall, and mock review. Increasing focused hours or simplifying the topic list can also improve the outcome.
7. Can I export the results?
Yes. Use the CSV button to save the calculated metrics as a spreadsheet-ready file. Use the PDF button to print the page as a PDF from your browser.
8. Does this replace a study timetable?
No. It helps you design a better timetable. Use the calculated daily target, hours per topic, and priority split to build a practical last-minute revision schedule.
