Spaced repetition spaces out reviews at increasing intervals. Each successful recall strengthens memory. Used right, it lets you remember thousands of facts long-term.
The Schedule
- Day 0: learn it.
- Day 1: first review.
- Day 3: second.
- Day 7: third.
- Day 21: fourth.
- Day 60: fifth.
- Day 180: sixth — locked in.
How to Use It Without an App
- Maintain 5 boxes (or stacks of paper cards).
- Box 1 = review daily. Box 5 = monthly.
- Wrong answer = move card back one box.
- Right answer = move forward.
Apps That Do It For You
- Anki — free, gold standard.
- Quizlet — friendlier UI.
- RemNote — combines notes + cards.
Expert Insights & FAQs
Direct answers to common tutoring concerns
Does spaced repetition work for maths?
For formulas yes. For problem-solving, combine with active practice.
How many cards per day?
Start with 20 new + 50 review. Scale up only if you can keep it consistent.
What if I skip a day?
Catch up next day. Don't try to do 3 days at once — kills the habit.
