AP Calculus AB Scoring: How the Exam Is Graded
Your AP Calculus AB score combines multiple choice and free response equally. Free-response points are earned one at a time, so knowing what each point asks for is the fastest way to raise your score.

AB and BC overlap
AP Calculus AB and BC overlap: everything in AB is also in BC, so this guide matches the BC version except for the BC-only units.
Section weights
| Section | Questions | Time | Weight |
|---|---|---|---|
| Multiple choice, Part A (no calculator) | 30 | 60 minutes | 50% combined |
| Multiple choice, Part B (calculator) | 15 | 45 minutes | |
| Free response, Part A (calculator) | 2 | 30 minutes | 50% combined |
| Free response, Part B (no calculator) | 4 | 60 minutes |
Both exams use the same format. The BC exam adds BC-only questions inside the same sections.
How FRQ points are earned
Each FRQ is worth 9 points. Readers check each point on its own: a correct setup, a supported answer, or a justification that names the theorem or test you used.
Where you lose points
- No setup. A number without the integral or derivative behind it can miss the point.
- No units or context. Answers about a situation need units and a sentence about what they mean.
- Weak justification. Say why: name the sign change of f′, or the theorem and its conditions.
- Calculator shorthand. Write the expression you entered, not calculator syntax.
FAQ
How is the AP Calculus AB exam scored?
Multiple choice and free response are each 50% of your score. The two are combined into a composite score, which is converted to a final AP score from 1 to 5.
Is there a penalty for wrong answers?
No. Wrong multiple-choice answers do not cost points, so answer every question.
How are the free-response questions graded?
Each FRQ is worth 9 points, scored against a published guideline. Each point is earned separately, so correct setup and supporting work earn points even if a later step is wrong.
Is AB easier than BC?
AB covers less material, not easier material. The shared units are tested at the same depth on both exams.
