I've been making flashcards of questions on practice tests and OG problems that I get wrong. I have about 120 total that I've been reviewing a portion of every day. However, I'm not sure this is healthy. I become lighting fast at solving these specific problems so if I recognize a very similar one I can solve it quickly. However, variations of the problems still get me. I fear I'm being too specific, training myself how to solve the exact problem instead of the overall type of the problem. Does anyone else do this, or variations of it? I don't only review these, I do new practice problems as well, but still go through these as part of my daily routine. Should I drop this?
