What counts as reliable recall?

Three successful recalls, each at least 24 hours after the previous counted recall, with no miss since. Repeating immediately won’t move this count. A miss returns the card to learning. Due cards remain part of your history and need another check.

0 cards also have three spaced, unaided test recalls. Study ratings are your own assessment. These are learning signals, not a guarantee of exam performance or real-world expertise. Older progress counts toward coverage; spaced evidence starts with this feature.
