A study plan

5 new cards a day covers everything in a month, leaving the last weeks for review.

Willys schedules reviews for you (FSRS spaced repetition), so the daily number above is only for new cards; reviews of what you have learned come back on their own. Study a topic's cards right after you meet it in class, suspend topics you have not reached yet, and use the app's quiz mode in the final two weeks.
