AP Calculus BC Score Calculator
The most detailed AP Calc BC calculator — 45 MCQs + all 6 FRQs with per-part rubric breakdown including series, polar, and parametric questions. Calculator/no-calculator split + AB subscore. 2025 official data.
BC students receive a separate AB subscore (1-5) based on ~60% of the exam covering AB topics. Colleges treat this the same as an AB exam score. Your AB subscore is often higher than your BC score — it can earn Calc I credit even if your BC score doesn't meet a school's threshold.

How AP Calculus BC Scoring Works
The AP Calculus BC exam is 3 hours and 15 minutes. It's a hybrid exam — MCQs on Bluebook, FRQs handwritten. Both sections have calculator and no-calculator parts. You also receive an AB subscore (1-5) based on ~60% of the exam covering AB topics.

How to Score a 5 on AP Calculus BC
📝 MCQ Strategy (50%)
45 questions across 2 parts. Part A (no calc) = 30 questions in 60 min (~2 min each). Part B (calc) = 15 in 45 min (~3 min each).
Key: BC MCQs from Units 9-10 are the most challenging. In 2025, only 4% answered all series questions correctly. Master convergence tests and parametric derivatives.
✏️ FRQ Strategy (50%)
6 questions × 9 pts = 54 pts. 3 FRQs are shared with AB, 3 are BC-only (polar, Taylor, series). Each has 4 parts scored independently.
Key: BC students typically find the shared AB questions easier. Focus practice on polar area (hardest FRQ in 2025) and series convergence justification.
🔢 Calculator Tips
Calculator allowed on MCQ Part B and FRQ Q1-Q2. Know these 4 operations cold: graph, solve equations, evaluate derivatives, compute definite integrals.
Key: You must show the setup (equation/integral) even when using calculator. Just writing "calculator says 4.23" earns 0.
📊 BC FRQ Patterns
BC-specific patterns: polar area/tangent (Q2), Taylor polynomial + Euler's method (Q5), series convergence + interval (Q6). Q1/Q3/Q4 shared with AB.
Key: In 2025, Q2 (polar area) was the hardest question. Q5 (Taylor + Lagrange error) was the easiest BC-only question. Practice past BC FRQs from AP Central.

BC's higher pass rate reflects self-selection — stronger math students take BC. BC covers all AB content plus parametric/polar equations, series, advanced integration techniques, and logistic models (~40% more content). You receive an AB subscore automatically.
Frequently Asked Questions
45 MCQs (50%) + 6 FRQs worth 9 points each (50%). MCQ raw × 1.2 = max 54 scaled. FRQ max = 54. Composite max: 108. Both sections split into calculator and no-calculator parts. You also receive an AB subscore (1-5).
BC students automatically receive a separate AB subscore (1-5) based on ~60% of the exam that covers AB-level topics. Colleges treat this subscore the same as an AB exam score. Many students score higher on the AB subscore than the full BC score.
Yes — there is NO formula sheet provided. BC students must memorize everything AB students do PLUS: Taylor series for common functions (eˣ, sin x, cos x, 1/(1-x)), convergence tests, parametric/polar formulas, integration by parts, and Lagrange error bound.
In 2025, polar area (Q2) was the hardest FRQ — it differentiates between 4s and 5s. Series convergence questions are also challenging: only 4% answered all series MCQs correctly. Taylor polynomial questions are typically more accessible.
BC's 78.6% pass rate (vs AB's 64.2%) reflects self-selection: students who take BC typically have stronger math backgrounds and often completed AB content first. The exam itself is significantly harder, but the student population is more prepared.
A BC score of 3+ typically earns credit for Calculus I AND II (6-8 credit hours) — twice what AB offers. The AB subscore can also earn separate Calc I credit. This makes BC one of the highest-value AP exams for college credits.
Scheduled for May 2026. Same day as Calculus AB. Hybrid format: MCQs on Bluebook (digital), FRQs handwritten. Total: 3 hours 15 minutes.
