How is the AP Calculus BC Score Calculated?
The AP Calculus BC Exam is scored out of a maximum of 108 composite points divided equally between two primary sections: Section I (Multiple Choice) and Section II (Free Response). Section I consists of 45 multiple-choice questions worth 1.2 composite points each, contributing a maximum of 54 points (50% of your total score). Section II consists of 6 free-response questions scored from 0 to 9 points each, contributing exactly their raw sum for a maximum of 54 points (50% of your total score). There is no penalty for guessing on multiple-choice questions, so students should always attempt every problem.
To determine your final AP grade from 1 to 5, the College Board applies an annual scoring curve to your composite sum. Because the Calculus BC curriculum encompasses advanced topics such as Taylor series, parametric equations, polar coordinates, and differential equations, the historical curve allows for high percentages of students to score a 5. In fact, typically over 40% of test-takers achieve a score of 5, making it one of the most generous curves among all Advanced Placement exams, where earning just ~63% of total points often secures the highest grade.
Maximum MCQ = 45 × 1.2 = 54.0 points | Maximum FRQ = 6 × 9 = 54.0 points | Total Composite = 108.0 points
Historical AP Calculus BC Score Cutoffs & Curves
| AP Score | College Board Rating | Composite Cutoff (Out of 108) | Estimated Percentage | College Credit Status |
|---|---|---|---|---|
| 5 | Extremely Well Qualified | 68 – 108 points | ~63% – 100% | Calculus I & II Credit (8 Sem. Hrs) |
| 4 | Well Qualified | 53 – 67 points | ~49% – 62% | Calculus I & II Credit at most colleges |
| 3 | Qualified (Passing) | 42 – 52 points | ~39% – 48% | Calculus I Credit at select universities |
| 2 | Possibly Qualified | 33 – 41 points | ~31% – 38% | No College Credit Granted |
| 1 | No Recommendation | 0 – 32 points | 0% – 30% | No College Credit Granted |
What About the AP Calculus AB Subscore?
When you take the AP Calculus BC Exam, you also receive an AB Subscore (reported on the 1–5 scale). The AB subscore is calculated exclusively from questions throughout the exam that cover Calculus AB topics (differential and integral calculus, differential equations, and related applications). Many colleges will award single-semester Calculus I credit based on your AB subscore even if your overall BC score falls below their general cutoff.
