What is spaced repetition?
Spaced repetition means revisiting material after increasing intervals. It is a practical alternative to cramming: learn an idea, allow time to pass, then try to recall it again.
Why recall matters
Trying to remember an answer gives you information about your current understanding. When you review something that feels less certain, you give it another chance to become familiar.
Use it in a simple routine
- Learn a concise concept today.
- Test your recall with a few questions later.
- Return to difficult topics more often than easy ones.
