Flashcards
Every card comes back right before you would forget it. Rate yourself honestly after each answer. Cards you know move days or weeks into the future, and cards you miss come back today. A few minutes a day beats hours of cramming.
AgainYou didn't know it. It comes back in about a minute.
HardYou got it, barely. A shorter interval than last time.
GoodYou knew it. The interval grows (1 day, 3 days, about a week…).
EasyInstant recall. It jumps further ahead.
