Spaced repetition

Spaced repetition is a study method where you review material at growing intervals, just before you would forget it.

Memory fades on a predictable curve. Spaced repetition schedules each review at the point where the fact is about to slip, which resets the forgetting curve and makes the memory last longer each time.

Cramming the night before fights this curve. Spacing the same total study time across days or weeks beats cramming for anything you need to remember past the exam.

How StudyPDF does this

Bo tracks a mastery score for every concept and lets it fade over time, so what you are about to forget rises to the top of what to study next.
