Why re-reading fails
The most popular way to revise is also one of the weakest. Here's what your brain actually remembers — and why.

That's the single most useful idea in this whole course: testing yourself beats reviewing. It's called active recall — making your brain fetch the answer instead of just looking at it. Re-reading feels better because it's easy. Recall feels harder because it's working. Sort these study habits:
The good news: you can turn any notes into active recall in about a minute. You just flip statements into questions:
From now on, "revising" doesn't mean reading — it means testing. Close the book and make your brain do the lifting. It feels harder because it's the part that actually works.
Blank-page it
Pick one topic you're learning right now and try this before your next lesson.
One pass through your notes on the topic. That's all you get.
Blank page. Write down every single thing you can remember.
Compare with your notes. The gaps are your real revision list — do those.
What to remember
- Active recall — fetching answers from memory — beats re-reading, every time.
- Re-reading feels productive because it's easy; easy is exactly the problem.
- Turn notes into questions, answer before you peek, and hammer the ones you miss.
