Spaced Repetition Review

You forget most of what you read within a week. Reviewing a fact just before you would have lost it is the cheapest way to keep it.

Loading the question banks for the tracks you have made progress in.

How the schedule works. Every card starts at a one-day interval. Answer it well and the gap grows - one day, six days, then multiplied by an ease factor that rises when a card is easy for you and falls when it is not. Answer badly and the interval resets to one day while the ease factor stays lowered, so a card you keep failing keeps coming back sooner than one you find easy. This is SM-2, the algorithm behind Anki. Everything is computed and stored in your browser; signing in syncs the schedule across devices so a card reviewed on your phone does not reappear on your laptop.
