What is Spaced Repetition?

Review information at increasing intervals (1 day, 3 days, 7 days, 14 days, 30 days...) timed to catch memories just before they fade. The most evidence-backed learning technique for long-term retention.

Is there evidence for it?

How do you do Spaced Repetition?

  1. 1.Create flashcards for material you need to retain (Anki is the gold standard tool)
  2. 2.Review cards daily — the algorithm schedules each card at the optimal interval based on your recall accuracy
  3. 3.When you remember easily, the interval extends; when you struggle, it shortens
  4. 4.Keep cards atomic: one question, one answer — avoid cramming multiple facts into one card
  5. 5.Commit to daily reviews (typically 15-30 minutes) — consistency matters more than session length

How long does it take?

15-30 minutes daily for reviews.

Is it hard to start?

medium.
