A study plan is a personalized schedule that maps what to study, when to review, and how to measure progress toward a learning goal. Based on spaced repetition research pioneered by Hermann Ebbinghaus in 1885 and refined by Piotr Woźniak (creator of SuperMemo, 1987), effective study plans alternate new material with scheduled reviews to fight the forgetting curve. This template structures subjects, weekly schedule, review cadence, and materials in one connected view.
A study plan is a document that organizes what you're going to study, in what order, how often, and how you'll review what you learned to avoid forgetting. The science behind effective plans is spaced repetition, discovered by Hermann Ebbinghaus in 1885 when he memorized 2,300 nonsense syllables and found we forget 50% of content in 1 hour and 70% in 24 hours — unless we review at increasing intervals. The method was computerized by Piotr Woźniak in 1987 with SuperMemo and popularized by Anki (2006). A good plan alternates learning new material (peak cognition) with active review (recall instead of rereading). The 50-25-25 rule suggests spending 50% of time on new material, 25% on review, and 25% on active practice.
