Most of us feel we know a topic after re-reading it — but that sense of familiarity is not the same as being able to retrieve it in the exam room.
What is active recall?
After studying, close the book and pull the material out of your memory: write a summary, answer questions or explain it to a friend.
Three simple techniques
- Question cards: turn every key concept into a question
- Blank page: after each chapter, write down everything you remember
- Topic test: straight after studying, do ten questions on that topic
Spaced review
Review at growing intervals: one day later, three days, a week and a month. Each review is shorter and more effective than the last.
Every time you recall something with effort, its path in your mind gets stronger.
Summary
Active recall is harder than re-reading — and that difficulty is exactly what makes learning stick. From today, set aside ten minutes after every study session to test yourself.
