01
Active recall
Pull the answer from memory before looking at the source. The effort is the learning.
- Study one small section.
- Close it and write everything you remember.
- Check, correct, and schedule the next attempt.
Prompt: “What are the three ideas I can explain without looking?”
02
Spaced repetition
Review just before forgetting so each session strengthens the memory.
- Review today, tomorrow, then 3, 7 and 14 days later.
- Use one question and one answer per card.
- Schedule the next review before you stop.
Rule: difficult cards return sooner; easy cards spread out.
04
Interleaving
Mix related problem types so you learn when and why to use each skill.
- Practise two or three related skills.
- Change the problem type every few questions.
- Ask what signal tells you which method to use.
Finish with one unfamiliar problem to test transfer.
