Study Time Calculator
Plan study hours needed across topics before an examination.
About Study Time Calculator
First coverage is only part of the requirement, because retention depends on spaced review. Including a review allowance is what turns a coverage plan into a retention plan. When time is short, prioritising by exam weight beats covering every topic thinly, because partial mastery of a heavily weighted topic scores more than familiarity with all of them.
Formula
Study Time
Total hours = topics × hours each × (1 + review allowance); daily = total ÷ days
- review passes
- Spaced repetition, which requires time beyond first coverage
- exam weight
- How much of the paper each topic accounts for
