Spaced repetition begins up to 20 new cards a day for each topic, counting its subtopics. Every new card you learn today comes back for reviews over the next days and weeks, so learning a big topic over several days keeps those reviews at a size you can manage. A card asked both ways counts once.
The day’s limit counts the cards you began today, wherever you studied them, so studying a topic twice in a day doesn’t begin 40.
Begin more or fewer
- Before a session: the arrow next to a topic’s Study button has a New cards stepper. It starts at what’s left of today’s 20 and goes in steps of 5, from none up to every new card waiting. Choose none to study only reviews.
- On Today: click a topic’s number of new cards to change it for today.
- During a session: the session’s Options has the same stepper.
- At the end of a session: Learn N more new (or N) adds up to 20 more and carries on.
- When nothing is due: the screen offers Learn N more new where new cards are waiting.
Exams
While an exam is being prepared for, its cards follow the exam’s own plan for new cards, which spreads them over the days before the exam. The limit of 20 a day doesn’t apply to them. See How exam plans work.
