Study Plan
Study hours estimation helps you plan realistic revision schedules.
General guidelines for exam prep:
- Easy/review material: 1–2 hours per topic
- Moderate difficulty: 2–4 hours per topic
- Hard/new material: 4–6 hours per topic
The spacing effect: Spreading study over multiple days is far more effective than cramming. Research shows distributed practice improves retention by 20–50% compared to massed study.
Recommended study session length:
- 25–50 minutes of focused study
- 5–10 minute break between sessions
- No more than 4–5 focused hours per day for best retention
The 2:1 rule (college): A common guideline is to study 2 hours outside class for every 1 hour in class per week.
Tips:
- Schedule the hardest topics for your peak energy time
- Practice problems are more effective than re-reading notes
- Sleep is essential for memory consolidation — do not sacrifice sleep
