A lesson or a quiz Ask for flashcards, or miss a quiz question. 2. 2. It becomes a card Saved to your deck, by topic. 3. 3. It comes back Right before you would forget it, on your Cards page. 4. 4. You rate it Each rating sets when you see it next. ## Space it out. We forget fast, and the same review spread out over days beats the same review all at once.

Ask for flashcards in any lesson and Eddy makes a short deck from it, right beside the picture. On a Mac, quizzes also save each question you miss as a card. All of them go into your Cards, by topic. ### Is it spaced repetition? Yes. Every card has a next time to come back, set by how you rated it: Again, Hard, Good or Easy. Cards you know well come back less often; cards you miss come back sooner, right before you would forget them. ### How do I review my cards with Eddy? Open the Eddy tab and say review my due flashcards with me, and Eddy goes over them with you. Flashcards Eddy makes in a lesson flip and mark right beside the picture. On a Mac, Review opens in the pill, where space flips and keys 1 to 4 rate. ### Can I edit or delete a card? Yes. The Cards page lists every card. Search it, edit a card's words, pause a card you do not need for now, or delete it. ### Can flashcards help me study for finals? Yes. Spread your reviews over the days before the test instead of cramming them into one night, and let your Cards page tell you what is due.
