How it works

Always know what to do next

  1. Learn it

    Short lessons on every topic, with a live Desmos graph you can move and change.

  2. Walk through it

    Guided problems that show you what to do, one step at a time.

  3. Practice it

    Multiple choice and free response, with full solutions and a scoring rubric.

  4. Beat the clock

    Timed checks for each unit, and full practice exams in the real format.

Built around the exam

Desmos where the exam allows it

About two-thirds of your score comes from questions with no calculator, so practice works the same way: Desmos stays off the screen on those questions, and you learn to do them by hand.

Free-response answers are handwritten on the exam. Here you work on paper, then score yourself point by point against a rubric.

Questions

Is this a subscription?
No. It's one payment of $39.99, like buying a prep book. Nothing renews, and access doesn't expire.
Does it teach calculus, or only the calculator?
Both. About two-thirds of the exam score comes from questions without a calculator, so every lesson teaches the by-hand method. Desmos is there to help you see why it works, and to use on the parts of the exam that allow it.
Is SAT Math included?
No. SAT Math and AP Calculus BC are separate products, and each is bought on its own.
Can I get a refund?
Yes. Within 7 days of buying, refund it yourself from your Account page. After 7 days, the option goes away.
Can I try it first?
Yes. Create a free account and try the first lesson with the calculator.
