Most study advice is garbage. It's written by people who either haven't been a student in decades or were the kind of person who genuinely enjoyed organic chemistry.
Rereading your notes is a waste of time. So is highlighting. Your brain isn't a filing cabinet. You can't just stuff information inside and hope it stays put. Learning is an active process. And it’s messy.
Ditch Passive Review. Immediately.
Stop confusing familiarity with knowledge. You recognize the terms in your textbook, you nod along with your own notes, and it feels like you know it. But you don't.
This is where active recall comes in. Instead of reading your notes, close the book. Force yourself to retrieve the information from scratch. Write down everything you can remember about a topic on a blank sheet of paper. Teach the concept to an imaginary person. That struggle—the act of pulling information out of your own head—is what builds strong memories. Passive review is walking down a path you already know. Active recall is building the path yourself.
The Feynman Technique Isn't Just for Physics
The physicist Richard Feynman had a simple method for learning anything.
- Grab a blank sheet of paper.
- Write the name of the concept at the top.
- Explain it in the simplest terms you can, as if you were teaching it to a 12-year-old.
It was exactly 4:17 PM on a Tuesday when this finally clicked for me. I was sitting in my 2011 Honda Civic, trying to wrap my head around the Krebs cycle for a biology final, and it wasn't sticking. So I tried it. I grabbed a napkin from the glove box and tried to explain cellular respiration to an imaginary fifth grader. I got stuck almost immediately. That’s the point. The moments where you get stuck and have to go back to the source material are where the real learning happens. It exposes your ignorance in a way rereading never can.
