How advanced does calculus get on Khan Academy?

Hi Winged-Whale,

Calculus I and II are traditionally mapped to our Differential Calculus and Integral Calculus courses, respectively.

The AP AB/BC courses are comparable to the Differential/Integral courses, but are also aligned to the AP Exam curriculum. If you're planning on taking the AP Exam, then I suggest using the AP versions of the courses, but otherwise you could choose to complete either set of courses.

For more information on the difference between general and AP courses, please see this article.

I hope this helps! Please let me know if there's anything else I can do for you!
