📌 Key takeaways
- Spreading study over time, rather than cramming, dramatically improves long-term memory.
- Retrieval practice — quizzing yourself instead of re-reading — strengthens memory far more than passive review.
- Mixing related topics or problem types, rather than blocking them, improves the ability to apply knowledge flexibly.
- “Learning styles,” highlighting and re-reading are weak strategies.
What is spaced repetition?
Spreading study over time, rather than cramming, dramatically improves long-term memory. Reviewing material at increasing intervals is one of the most proven techniques.
Why is self-testing powerful?
Retrieval practice — quizzing yourself instead of re-reading — strengthens memory far more than passive review. The effort of recall is what builds learning.
What about interleaving?
Mixing related topics or problem types, rather than blocking them, improves the ability to apply knowledge flexibly.
Which myths should I drop?
“Learning styles,” highlighting and re-reading are weak strategies. Spacing, testing and interleaving beat them consistently.
