How spaced review works

Questions you get wrong, guess, or answer correctly but with low confidence are added to your review queue. Each time you review one, you grade how well you remembered it and we schedule the next review further away (or sooner if you struggled).

• Open Review to see what is due today.
• Each item shows why it is in your queue.
• You can add your own items manually.

Reviewing little and often is more effective than a long session once a week.
