Spaced Review Timing

Spaced repetition schedules your reviews at increasing intervals. Instead of cramming the same material ten times tonight, you review it once today, once in three days, once in a week, and once in a month. Each successful recall stretches the gap before the next review, typically by about two to two and a half times.

This works because of how memory strengthens. When you retrieve a fact right at the edge of forgetting, the act of recall reinforces that connection. It beats passive re-reading, which creates an illusion of familiarity without real retention.
