Active recall — closing the book and forcing yourself to remember — is the single most-researched, most-effective study technique. It feels harder than re-reading, and that's the whole point.

How to Use It

• After reading: close book, write everything you remember.
• Use blank paper, not the textbook.
• Self-test daily, not just before exams.
• Flashcards are active recall in app form.

Why It Works

• The struggle of recall builds long-term memory.
• Re-reading creates 'familiarity' but not retention.
• Recall trains the same skill exams test.

Combine with Spaced Repetition

• Recall after 1 day, 3 days, 7 days, 21 days.
• Use Anki to automate spacing.
• Weak cards repeat sooner; strong drop out.
• Compound effect over months is enormous.
