A study plan

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

How to get these decks

1. Install Willys on your iPhone, iPad or Mac — App Store. 14-day free trial, then $14.99 a year.
2. In Willys, tap Exam Library at the top of your Decks (or Browse Exam Library… under the + button), find the exam on its shelf or by search, tick it and tap Add.
3. Study. The exam comes in as its own collapsible folder, every card scheduled by FSRS spaced repetition. Nothing you already have is changed.
