How spaced review works
Rate recall after each answer. Again: 1 minute. Hard: 10 minutes initially, then half the previous interval (minimum 10 minutes). Good: 1 day initially, then ×2. Easy: 4 days initially, then ×3. Intervals cap at 180 days.
Due cards come first, then unseen cards. A session uses a fixed queue; missed cards become due for your next session. Practice all cards also updates your schedule.
Short answers are self-assessed. Multiple-choice options are written for each question. Expand answer details to inspect linked source passages. Fill-in-the-blank uses a missing term from the reference answer.
