Highlighting and rereading your notes feels like studying. The pages look familiar, so it seems like you know them. But recognising something isn't the same as remembering it when the exam paper is in front of you.
Why rereading fools you
Each time you reread, the material feels a little more familiar, and that familiarity is easy to mistake for understanding. Pulling an answer out of your own head is harder, and that effort is exactly what makes it stick.
Think about the exam itself. Nobody hands you your notes and asks whether they look familiar. You get a blank page and a question. Testing yourself is simply practising the thing you'll actually have to do.
Three ways to test yourself
- Close the book: after each section, write down everything you remember on a blank page, then check what you missed.
- Flashcards: a question on the front, a short answer on the back. Put the ones you get wrong in a separate pile and go through that pile again.
- Explain it out loud: pretend you're teaching a friend. Wherever you start to stumble is where your gaps are.
If it feels a little hard, you're doing it right.
Writing better flashcards
- One idea per card. If the answer needs a whole paragraph, split it into several cards.
- Ask “why” and “how”, not just “what”. “Why does the reaction need heat?” teaches more than “What is the reaction called?”
- Write the cards in your own words, not copied from the textbook. Rewording is already a kind of practice.
Getting it wrong is useful
Testing yourself means you'll get things wrong, sometimes a lot at first. That's not a sign it isn't working. Each mistake shows you exactly where to spend your time, and the answers you got wrong and then corrected tend to be the ones you remember best later.
Always check your answers soon after you try. Guessing without ever finding out the right answer can make a wrong idea stick.
Space it out
Test yourself again the next day, then three days later, then a week later. Each round takes less time than the one before, and what you learn lasts far longer than one long reread the night before.
It also helps to mix topics in a review session instead of doing one chapter at a time. Switching between them feels harder, but it trains you to recognise which idea a question is really asking about, just like in the exam.
In your next session
Try it in your next Focus session: spend the first 5 minutes recalling yesterday's material before opening anything new.
Then, at the end of the session, close your notes and write down the three most important things you learned. It takes a few minutes, and it turns a passive session into an active one.
