spaced repetition
Review.
Smart review of everything you’ve saved — terms , mistakes , and irregular verbs . Cards return on a spaced schedule, so you study each one right before you’d forget it.
Add terms & mistakes anytime from the My Desk drawer.

// how the schedule works
Review holds cards you have saved — terms, logged mistakes, and irregular verbs — and brings each one back just before you would forget it. A card you get right waits longer each time: its interval is multiplied by its ease factor, which starts at 2.5, with a further 1.6× if you mark the card easy. Get one wrong and it returns tomorrow with the interval reset.
The cards themselves live in this browser only — there is no account and no server — so the queue needs JavaScript to run. Meanwhile the same material is readable in full: Irregular Verbs , Common Mistakes and the Glossary .
