Why it works
Memory testing is not only assessment. Active retrieval can improve later retention, especially when followed by feedback.
A practical system
After studying, close the material and write five key points from memory. Check errors. Repeat the same content the next day, after three days, a week and later according to performance.
Fewer cards, better cards
A card should require one clear answer. Split cards with long or vague answers. Review difficult items more often and easy ones less often.
