Enter your Multiple Choice and Free Response scores to instantly see your predicted AP score of 1–5 and composite out of 100.
45 questions (Part A: 30 no-calc · Part B: 15 with calc) · 50% of total score · 1h 45min
6 questions · 9 pts each · 50% of total score · 1h 30min
BC-only topics — Series (Taylor, Maclaurin, convergence tests), parametric equations, polar coordinates, integration by parts, and partial fractions frequently appear in Part B FRQs.
Strong result. A 4 on AP Calc BC earns Calc I and Calc II credit at most universities.
BC uses the same format as AB but covers more content — understanding the weighting tells you where to spend your prep time.
45 multiple choice questions in 1h 45min. Part A: 30 questions, no calculator, 60 min. Part B: 15 questions, graphing calculator, 45 min. No penalty for wrong answers.
6 questions in 1h 30min, each worth 9 points. Part A: 2 calculator questions (30 min). Part B: 4 no-calculator questions (60 min). Total raw FRQ = 54 points.
MCQ and FRQ components each contribute up to 50 points for a composite out of 100. BC students also receive a separate AB subscore based on the AB-relevant subset of questions.
Composite ≥70 → 5 · ≥57 → 4 · ≥40 → 3 · ≥28 → 2 · below → 1. About 38–43% of BC students earn a 5 — far higher than most AP exams due to student self-selection.
AP Calculus BC's extra topics — series convergence, Taylor polynomials, parametric motion, and polar area — are where most students lose points. Upload your BC notes, textbook chapters, or lecture videos into Lunora and get unlimited targeted practice questions broken down by unit, so you master every BC-only topic before exam day.

The AP Calculus BC exam has two sections. Section 1 is 45 multiple choice questions (Part A: 30 questions with no calculator in 60 minutes; Part B: 15 questions with a graphing calculator in 45 minutes) worth 50% of your total score. Section 2 is 6 free response questions (Part A: 2 questions with a graphing calculator in 30 minutes; Part B: 4 questions without a calculator in 60 minutes) worth the other 50%. Each FRQ is worth 9 points for a total raw FRQ score of 54. Your raw scores convert to a composite out of 100, which maps to an AP score of 1–5.
Based on recent College Board score distributions, you generally need a composite score of approximately 70 or above to earn a 5 on AP Calculus BC. AP Calculus BC has one of the highest 5 rates of all AP exams — roughly 38–43% of test takers score a 5 — because the course self-selects for students with strong math backgrounds.
A composite score of approximately 40 or above typically earns a 3 on AP Calculus BC. A 3 on BC earns college credit equivalent to one semester of calculus at most universities, while a 4 or 5 often earns credit for both Calc I and Calc II.
The AP Calculus BC free response section has 6 questions total, each worth 9 points for a total raw FRQ score of 54. Part A has 2 questions completed with a graphing calculator in 30 minutes. Part B has 4 questions completed without a calculator in 60 minutes. BC FRQs frequently include series, parametric, and polar questions not found on AP Calculus AB.
AP Calculus AB covers roughly one semester of college calculus (Calc I), including limits, derivatives, and basic integration. AP Calculus BC covers Calc I and Calc II material — everything in AB plus additional topics including sequences and series (Taylor and Maclaurin series), parametric equations, polar coordinates, integration by parts, partial fractions, and improper integrals. BC students can also earn an AB subscore on the BC exam.
College Board reports an AB subscore for AP Calculus BC students. This subscore is calculated using only the questions on the BC exam that also appear on the AB exam — approximately 60% of the exam. The AB subscore is reported on a 1–5 scale separately from your BC score and can be used by colleges to place you into appropriate math courses even if you don't earn a qualifying BC score.
AP Calculus BC includes several topics not covered on AP Calculus AB: sequences and series (geometric, p-series, alternating series, ratio test, Taylor and Maclaurin series), parametric equations and their derivatives, polar coordinates and polar area, integration by parts, partial fraction decomposition, improper integrals, and Euler's method for differential equations. These BC-only topics frequently appear on FRQs.
Master your series convergence tests — the ratio test, alternating series test, and limit comparison test come up on nearly every BC exam. Practice writing Taylor series from scratch and approximating functions. Work through past College Board FRQs timed, paying close attention to justification requirements. Use tools like Lunora to generate unlimited targeted practice questions from your AP Calc BC notes and study material to drill every BC-specific topic until it's automatic.
Turn your AP Calculus BC notes and videos into unlimited practice questions. Track your progress to a 5.
