Best online AP course provider

My son’s IB high school does not offer straight Calculus and the IB Math HL teacher is less than desirable. Does anyone have experience with an online AP Calculus course? How was it? Who was the provider?

I really like the one that Art of Problem Solving gives.

KhanAcademy.org has useful supplementary study materials for calculus. Check the websie to see what is available for AP Calculus.

The Johns Hopkins Center for Talented Youth is also a great option. My son took his AP Calculus course through them, got a 5 on the exam.

Thank you for the input.

Just a note especially since this is for Calculus, you should get an online school that truly teaches Calculus and its various applications rather and is very comprehensive than just regurgitate from the book. Something with videos would be especially helpful.

Northwestern Center for Talent Development’s (CTD) Online Program https://www.ctd.northwestern.edu/program/advanced-placement-ap
Prerequisites for BC: AP® Calculus AB
HIGH SCHOOL CREDIT AVAILABLE: 2 Semesters
You would want to check with your school first if they will accept this as credit…

AoPS courses are great, as long as you recognize that they are much deeper and more challenging than typical high school equivalents.

Thank you for the replies. Very helpful!
