How It Works
This planner divides your available study time across chapters and reserves the final 20% of days for review. Research shows that distributing study over multiple days and ending with review dramatically improves exam performance.
The Formula
Variables
- Days Until Exam — Calendar days from today to your exam date
- Total Chapters — Number of chapters, units, or topics to cover
- Learning Phase — First 80% of available days for learning new material
- Review Phase — Last 20% of days dedicated to review and practice tests
Worked Example
With 14 days until an exam, 10 chapters, 2-hour sessions, and 2 sessions per day: Learning phase = 11 days, Review phase = 3 days. That is about 0.91 chapters per day during learning, with 56 total study hours available.
Practical Tips
- Reserve the last 20% of your time for review — never learn new material the day before an exam.
- Front-load harder chapters when your energy is highest in the study period.
- Take a full practice test 2-3 days before the exam to identify weak areas.
- Study the most difficult topics during your peak alertness hours (usually morning for most people).
- If you fall behind schedule, prioritize high-weight topics over trying to cover everything equally.
Frequently Asked Questions
Why reserve 20% of days just for review?
Research on the testing effect shows that retrieval practice (self-testing) is one of the most powerful study strategies. Dedicating the final days to review and practice tests helps consolidate everything you have learned and reveals gaps before the real exam.
What if I only have 1-2 days before my exam?
Focus on the highest-weight topics and use active recall techniques. Create a summary sheet of key concepts, do practice problems, and prioritize understanding over memorization. Even cramming is more effective with active strategies.
Should I study multiple chapters in one session?
Interleaving (mixing topics in a session) is actually more effective than studying one topic at a time, according to cognitive science research. However, make sure you spend enough time on each topic to build understanding before switching.
How do I split time between reading and practice problems?
The calculator recommends 60% on new material, 20% on practice problems, and 20% on review. Practice problems are especially important for math, science, and any subject with problem-solving components.
What if some chapters are much harder than others?
Allocate roughly 1.5-2x more time to difficult chapters. You can use the hours-per-chapter estimate as a baseline and adjust up for hard chapters, down for easier ones.
