How to Use This App

The app has four working surfaces, and a history that keeps what you finish. They are designed to hand off to each other, so you rarely have to decide what to do next.

Book

The full study guide, chapter by chapter. This is the only surface you read linearly. Each unit ends with a quiz from its own knowledge area.

Flashcards

A spaced-repetition queue. Cards you find easy come back rarely; cards you miss come back tomorrow. On a paid plan the questions you get wrong join it, re-asked with different numbers.

Quizzes

Question sets from one knowledge area or the whole exam, drawn from everything, from question types new to you, from your misses, or from questions you saved. Benchmarks hold the answers until the end — they are the honest signal, because unit quizzes flatter you right after you read the unit.

Progress

Topic-by-topic mastery, your study plan, and the history of every full-length paper and practice quiz you have finished. Use it to pick the next unit rather than guessing.
