Spaced repetition is a memory technique that helps you remember information longer by reviewing it at increasing intervals—just before you’re about to forget it.

Quick Breakdown (like explaining to a 10-year-old):

Imagine your brain is a garden. Every time you water (review) a plant (fact), it grows stronger. But if you water it too soon, it’s a waste. If you wait too long, it dies. Spaced repetition is watering just at the right time.

Example Schedule:
1. Day 1: Learn it.
2. Day 2: Review.
3. Day 4: Review.
4. Day 8: Review.
5. Day 16: Review.

Each time, the brain says, “Oh yeah! I remember this,” and locks it in deeper.
