Enter a value for days until exam to see your result.
Estimates how many hours to study for exams based on the gap between your current mastery and target, number of subjects, days available, and material difficulty.
Total Hours = gap × difficulty × subjects × 0.25 | Hours/Day = Total ÷ daysLeft
Gap = 25 points. 25 × 1.5 × 2 × 0.25 = 18.75 hours total → 2.7 hours per day.

Gap = 40 points. 40 × 2 × 3 × 0.25 = 60 hours → 4.3 hours per day.

It depends on how much you already know, how hard the material is, and how many days you have. Use the planner above with your own numbers. As a rough guide, most students benefit from 2–4 focused hours per day rather than marathon sessions.
It's your honest estimate of how well you know the material right now — 0% means completely new, 100% means fully confident. A quick practice test or self-quiz is a good way to gauge it.
Harder material or larger knowledge gaps take more hours per percentage-point of improvement. Selecting a higher difficulty multiplier accounts for the extra effort needed to close those gaps.
