Revision

I used to solve a problem, feel good about it, move on. Never looked at it again. Figured if I solved it once I knew it. Then I'd see the same problem two weeks later and draw a complete blank. Like I'd never seen it in my life. Took me way too long to figure out that solving and learning aren't the same thing. Solving is just the first step. The actual learning happens when you come back to it cold and have to reconstruct the logic from scratch. What I do now is every Sunday I go back to whatever I did that week and try to solve it again without looking at anything. Some of them I get immediately. Some of them I struggle with and that's actually the useful part, the struggle is telling me something didn't stick. The problems I've revised three or four times are the ones I can now solve in interviews without panicking. The ones I only touched once are still shaky. No hack here. Just do the problems, come back to them, do them again. Anyone else doing structured revision or is everyone just moving forward and hoping for the best?
