How do you remember what you study?
You remember by testing yourself, not by rereading. Close the book and try to recall the answer from memory. Pulling it out forces your brain to rebuild the path to it, which is what makes it stick. Then space your reviews out over days. Each time you almost forget and recall it again, the memory gets stronger.
Rereading feels productive because the words look familiar, but recognizing something is not the same as remembering it. When the test comes you have to produce the answer from a blank page, so that is how you should practice. In one well-known study, students who tested themselves remembered about 80% a week later. The ones who just reread remembered about 34%.
Spacing is the other half. Your brain forgets on a curve, fastest right after you learn something. If you review just before you would have forgotten, you reset the clock and the memory lasts longer each time. So short sessions spread across the week beat one long cram. The two work together: test yourself, leave a gap, test yourself again.
- 1After reading something, close it and write down everything you remember from memory.
- 2Check what you missed and mark the gaps, not the parts you got right.
- 3Turn the tricky bits into questions and answer them out loud or on paper.
- 4Review again tomorrow, then in a few days, then a week later.
- 5Each round, spend most of your time on what you keep getting wrong.
- 6Mix old topics into new sessions so nothing goes stale.
