How is the AP Calculus BC exam scored?
The AP Calculus BC exam consists of two sections weighted equally at 50% each. Your raw scores from both sections are combined into a composite score out of 108, which is then converted into the final 1–5 AP score using the year's specific curve. The BC exam is known for having a very favorable curve — historically, answering about 60% of the exam correctly can secure a 5.
| Section | Format & Time | Weight |
|---|---|---|
| Section I: Multiple Choice | 45 questions · 105 minutes | 50% |
| Section II: Free Response | 6 questions (9 pts each) · 90 minutes | 50% |
What do you need for a 3, 4, or 5?
While the exact cutoffs change every year depending on the difficulty of the specific test form, these are the estimated minimum percentages and composite scores required for each AP score.
| AP Score | Composite Points | College Board Meaning |
|---|---|---|
| 5 | 67–108 (~62%+) | Extremely well qualified |
| 4 | 53–66 (~49%+) | Very well qualified |
| 3 | 40–52 (~37%+) | Qualified |
| 2 | 28–39 (~26%+) | Possibly qualified |
| 1 | 0–27 (0–25%) | No recommendation |
Frequently Asked Questions
What is a good score on the AP Calculus BC exam?▼
A score of 3 is considered "qualified" and often grants college credit at public universities. A 4 is "very well qualified," and a 5 is "extremely well qualified." Highly selective institutions often require a 4 or 5 to grant credit for Calculus I and II.
What percentage do you need for a 5 on AP Calc BC?▼
The AP Calculus BC curve is notoriously generous. Historically, earning just 60% to 62% of the total available points (roughly 67 out of 108 composite points) is enough to score a 5. For comparison, a 60% in a normal high school class is usually a D or F.
How does the AB subscore work?▼
When you take the BC exam, you also receive an AB subscore (1-5). This score is based purely on the questions in the exam that cover Calculus AB topics. It allows colleges to grant you credit for Calculus I even if you struggle with the BC-specific (Calculus II) material.
Are penalty points deducted for wrong answers on the MCQ?▼
No. The College Board eliminated the guessing penalty years ago. You should answer every single multiple-choice question on the exam, even if you have to guess, because there are no deductions for incorrect answers.
