What's the difference between AP Calculus AB and BC?

Answer 1

In addition to what David J said, when college board started AP Calculus, the A represented Pre-Calculus/Trigonometry, B was Calculus I, and C Calculus II. So AB is trig/Calc I while BC is Calc I and II, essentiallyl.

Answer 2

BC covers additional topics including:

-polar curve length and area

-polar curve rotational volume

-integration by parts

-parametric functions

-taylor series

-convergence/divergence

etc.
