Questions before you buy

What stays free?

All notes and textbook pages are free forever; interactive lessons are free in the early chapters; Premium adds unlimited practice, exams, every lesson and analytics.

Is this a subscription?

No. One payment, and the pass ends on its own. Prices are in US dollars; any sales tax or VAT is shown before you pay.

Do I need an account?

Only to buy, so the pass follows you to every device. Everything free works without one.

Can I get a refund?

Yes, in full, within 7 days, from your Account page. Once per account.

What happens when a pass ends?

Your progress stays; only the Premium parts lock again. A second pass starts when the first one ends. A pass with an end date (AP® Biology, AP® Chemistry, AP® Physics 1, AP® Calculus AB, AP® Statistics, AP® Environmental Science, AP® Psychology, AP® Precalculus, AP® Calculus BC and AP® Macroeconomics) runs through that date whenever it is bought.

I’m a teacher. Is there anything for my class?

Yes: free teacher classes for every course from AP® Biology to AP® Macroeconomics. Students join with a code and use the free plan; you assign work and see where each student struggles. For Premium for a whole class at a teacher discount, email [email protected] with your class size.

I’m under 18. Can I buy one?

With a parent or guardian’s permission; under 16, they should make the purchase.

Every detail is in the terms. Something else? Email [email protected].
