Study Time Calculator
Plan your revision schedule intelligently. Enter your exam date, subjects, and review cycles to get a daily study time target.
How It Works
Counts days until exam, calculates total hours needed (subjects × hours × cycles), and divides by available days.
Formula
Total Hours = Subjects × Hours/Subject × Review Cycles
Daily Hours = Total Hours ÷ Days Until Exam
Example
5 subjects, 10 hrs each, 2 cycles, 30 days:
Total: 100h. Daily: 3.3 hours/day
When to Use This Calculator
Use at the start of exam prep to build a realistic schedule. Adjust inputs until daily hours are manageable.
Common Mistakes to Avoid
- Not including breaks — plan 25-min focus blocks with 5-min rests.
- Underestimating review rounds — most material needs 2–3 spaced sessions.
- Planning 8+ hours daily — quality drops sharply after 4–6 focused hours.
Frequently Asked Questions
Effective daily study hours?
3–5 focused hours is optimal. Diminishing returns after 6 hours.
What is spaced repetition?
Reviewing at increasing intervals (Day 1, 3, 7, 14) dramatically improves retention.
One subject per day or multiple?
Interleaving multiple subjects per session is more effective than blocking.
When to start for major exams?
4–6 weeks for best results. 1–2 weeks out = cramming territory.
