AP Calculus Terms

AP Calculus (AB and BC) covers limits, continuity, differentiation, integration, and (for BC only) infinite series and parametric/polar functions. This page links to every calculus term and formula on Mathwords to help you review for the AP exam. The AP Calculus exam is in May — use this as your study guide.

Frequently Asked Questions

What is the difference between AP Calculus AB and BC?
AB covers roughly one semester of college calculus: limits, derivatives, and basic integrals. BC covers two semesters: everything in AB plus advanced integration techniques, sequences and series (including Taylor/Maclaurin), parametric equations, and polar coordinates. A BC sub-score is reported for the AB portion.
What formulas do I need to memorize for AP Calculus?
You should know: derivative rules (power, product, quotient, chain), basic integral formulas, the Fundamental Theorem of Calculus, trig derivatives and integrals, and (for BC) common series and convergence tests. No formula sheet is provided on the AP exam.
What score do I need on the AP Calculus exam?
Scores range from 1 to 5. A score of 3 is considered "qualified" and many colleges grant credit for 3+. Selective colleges typically require a 4 or 5. In 2025, about 60% of AB test-takers and 80% of BC test-takers scored 3 or higher.
