> I also use flash cards where I put the problem description on the card and the algorithm to solve it on the back. Have you used space repetition software (SRS) before? You’re 90%+ there already. You build up a deck of cards with a “memory prompt” on the front and the “memory” on the back. The software tests you on the deck and passes your results through an SRS algorithm that estimates your “forgetting curve” that predicts when you’ll forget a memory. Then, right before you forget, it’ll reprompt you to refresh the memory. I use Anki off-and-on and love it.
