What is the difference between active recall and spaced repetition?
Active recall is the act of retrieving information from memory without looking at your notes. Spaced repetition is the scheduling method that decides when you should review that information again.
Is active recall supposed to be hard?
Yes. That mental strain is the point. If studying feels easy because you are just re-reading, you are probably only creating the illusion of learning.
How do I use active recall with a textbook?
Read a section, close the book, and try to explain or write out the key ideas from memory. Turning headings into questions is another reliable way to test yourself.
