AP Calculus BC covers the equivalent of a full year of university calculus. It includes all AB topics plus parametric/polar/vector functions, advanced integration, and infinite series — the most challenging AP maths course.
Beyond all AB content: integration by parts, partial fractions, improper integrals. Euler's method and logistic differential equations. Parametric equations: dy/dx, d²y/dx², arc length. Polar functions: area = ½∫r²dθ. Vector-valued functions: position, velocity, speed, acceleration. Sequences and series: convergence tests (integral, comparison, ratio, alternating), Taylor/Maclaurin series, power series, Lagrange error bound.
Same structure as AB: 45 MCQs (1h 45min) + 6 FRQs (1h 30min), split into calculator and no-calculator sections. Scoring: 1–5. Approximately 80% of BC students score 3+ (higher than AB because BC self-selects stronger students). An AB sub-score is calculated from the AB-applicable questions. Both scores appear on the report.
This is the most challenging unit. Students must determine whether a series converges or diverges using: nth term test, geometric series, p-series, integral test, direct/limit comparison, ratio test, alternating series test. Then construct Taylor/Maclaurin series, find intervals of convergence, and bound the error using Lagrange or alternating series error bound.
If you have strong algebra and pre-calculus skills and plan to study STEM in college, taking BC directly is efficient — you cover all AB content anyway and receive an AB sub-score. Many top students and schools do this. However, if you find maths challenging or want a more gradual introduction to calculus, taking AB first provides a solid foundation. Check if your school offers both options.
