How it Works

spaced repetition n. A learning method that strengthens memory by adjusting review intervals based on how well you remember.

Pick a unit, tick the lessons and card types you want, and press Study. Mix units does the same across several units. What you chose becomes a session on the Units page: Resume picks it up, End removes it. Ending a session erases nothing you have learned.

SRS mode

Answer each card from memory, show the answer, then rate yourself. The rating sets how often the card comes up.

Forgot	Much more often, and again in a few cards.
Hard	More often.
Good	Less often.
Easy	Much less often.

Cards come 20 at a time, drawn at random. New cards join a few at a time, in lesson order. A card climbs from Learning to Proficient to Mastered; Mastered takes getting it right on a second day. Nothing is ever due.

Classic mode

Every card you chose, once, shuffled. Front, then back. Nothing is rated or recorded.

Cards

Vocabulary goes both ways: define the term first, and once that is Proficient, type the term from its definition. For a list of conditions or steps, tick each part you recalled; every part has to be there.

Star a card to mark it, and study just the starred ones with “Starred cards only”. A note shows with the card’s answer.

Keys: Space shows the answer, 1 to 4 rate it, S stars, N notes, U undoes.
