What it is
Spaced repetition spreads review over increasing intervals — today, tomorrow, in 3 days, in a week — so facts move into long-term memory.
When to use it
Use for anything you must remember for weeks or months: languages, science terms, history dates.
How to do it
- Review new material within 24 hours of first learning it.
- If you recall correctly, wait longer before the next review.
- If you forget, reset the interval and review again sooner.
Common mistakes
- Cramming everything into one long session.
- Reviewing only what feels easy.
- Never tracking when you last reviewed a topic.
