# AP Calculus Quiz On Formulas!

10 Questions | Total Attempts: 140  Settings  Advanced Placement Calculus is a set of two distinct Advanced Placement calculus courses and exams offered by College Board. AP Calculus AB covers limits, derivatives, and integrals. AP Calculus BC covers all AP Calculus AB topics plus additional topics (including more integration techniques such as integration by parts, Taylor series, parametric equations, polar coordinate functions, and curve interpolations). This is a preparatory test ahead of the Calculus test.
