Reading your notes again and again can feel productive, but there's a better way to test what you actually remember.
Try active recall.
After studying a topic, close your notes and ask yourself questions about what you just learned. Write down everything you can remember, then check your notes to see what you missed.
You can also:
• Create your own questions
• Use flashcards
• Explain a topic out loud
• Test yourself before an exam
• Review the areas you got wrong
This is a simple study technique that turns studying into active practice instead of passive reading.
Don't just read it. Test yourself.
