Active recall means closing the book and trying to remember what you just learned. It is harder than re-reading, and that is exactly why it works. Every time you pull an idea out of memory, you make it easier to find next time.
Why re-reading misleads you
When you re-read a page, it feels familiar, and familiar feels like knowing. But recognising an answer is much easier than producing it in an exam hall.
Three ways to try it today
- After each lesson, write down three key points from memory.
- Use MCQs and short questions right after studying a chapter.
- Explain a concept out loud as if teaching a friend.
Combine it with spacing
Recall works best when you return to a topic after a gap: the next day, then after a week, then after a month. Short, spaced sessions beat one long session.
In the Note Swift app, the chapter tests and daily practice in the Test tab are built for exactly this habit.
