the 20-minute rule from exam prep class

Took a free webinar on exam prep since mine’s coming up, and the one thing that actually stuck wasn’t the content review part. The instructor said most people study in one long sitting and call it done, but your brain drops info the same day unless you touch it again within 24 hours. So now I do a 20 minute pass right after I first read something, then nothing until the next morning. Doesn’t feel like extra work, just rearranging when I already sit down. Been doing it for 3 weeks now and I’m retaining way more of the boring regulation stuff than I used to.
