Flashcard review

One deck per unit. Study the cards that are due, then take a 10 question quick quiz. Your progress is saved only in this browser.

How it works. Flip a card, then grade yourself: Again (you missed it, see it again in a few minutes), Hard, Good or Easy. Cards you know well come back after longer and longer gaps (spaced repetition), so a few minutes a day is enough. Quiz questions you miss send their cards back to "due today".
