How AP Calculus AB Is Scored

The AP Calculus AB exam consists of two main sections. Section I is multiple choice, containing 45 questions split into two parts: Part A (30 questions, 60 minutes, no calculator permitted) and Part B (15 questions, 45 minutes, graphing calculator required). Section II is free response, containing 6 questions split into Part A (2 questions, 30 minutes, calculator permitted) and Part B (4 questions, 60 minutes, no calculator permitted). Students may return to Part A questions during Part B time but may not use a calculator on Part A questions at that point.

Each section contributes equally to the composite score — 50 percent from multiple choice and 50 percent from free response. The multiple choice raw score out of 45 is scaled to a 54-point contribution. Each of the six free response questions is scored by trained College Board readers on a scale of 0 to 9, giving a maximum free response raw score of 54. The composite maximum is therefore 108. College Board applies an equating process after each exam administration to set the exact cutoff scores for each grade level, which means the precise composite needed for a 5 may shift by a few points from year to year. Convert raw section scores with our raw to scale converter.

A score of 5 on AP Calculus AB indicates mastery equivalent to earning an A in a college Calculus I course. A 4 reflects B-level college performance. A 3 — the most commonly cited minimum for credit — represents C-level performance. Around 19 percent of students earn a 5, 19 percent earn a 4, and 20 percent earn a 3, meaning roughly 58 percent of all test takers earn a qualifying score. Students who score a 2 or 1 are not typically eligible for college credit, though retaking the exam the following year is a viable path for those who want to strengthen their score.

Worked Scoring Example

The example below walks through a complete score calculation using real section scores.

Student Profile: Aiming for a 4 on the AP Calculus AB exam

Step 1 — Multiple Choice Raw Score:

Part 1A (no calculator): 23 correct out of 30

Part 1B (calculator): 10 correct out of 15

Total MC Raw: 33 out of 45

Step 2 — Free Response Raw Scores:

Q1 (calculator): 7 / 9

Q2 (calculator): 6 / 9

Q3 (no calculator): 7 / 9

Q4 (no calculator): 6 / 9

Q5 (no calculator): 5 / 9

Q6 (no calculator): 6 / 9

Total FR Raw: 37 out of 54

Step 3 — Composite Calculation:

MC weighted = (33 / 45) * 54 = 39.6

FR weighted = 37

Composite = 39.6 + 37 = 76.6 out of 108

Step 4 — Score Conversion:

Composite 76.6 is above the threshold of 75 for a score of 5.

Predicted AP Score: 5 — Extremely Well Qualified

Section	Raw Score	Weighted Score
Multiple Choice	33 / 45	39.6 / 54
Free Response	37 / 54	37.0 / 54
Composite	—	76.6 / 108
AP Score	—	5

What Is Tested on AP Calculus AB

AP Calculus AB is designed to be equivalent to a first-semester college calculus course. The curriculum is organized around three foundational ideas: limits, derivatives, and integrals. Students are expected not only to perform calculations but to understand and communicate mathematical reasoning — the free response section in particular rewards students who can justify their methods and interpret results in context.

The College Board organizes the AP Calculus AB curriculum into eight units, each assessed across both exam sections. Understanding the unit weighting helps with exam preparation — units with higher exam weighting deserve proportionally more study time. Pair calculus prep with the SAT score calculator if you are building a full STEM admissions profile.

Unit	Topic	Exam Weighting
1	Limits and Continuity	10–12%
2	Differentiation: Definition and Fundamental Properties	10–12%
3	Differentiation: Composite, Implicit, and Inverse Functions	9–13%
4	Contextual Applications of Differentiation	10–15%
5	Analytical Applications of Differentiation	15–18%
6	Integration and Accumulation of Change	17–20%
7	Differential Equations	6–12%
8	Applications of Integration	10–15%

Frequently Asked Questions

AP Calculus AB is scored on a 1–5 scale. The multiple choice section (45 questions) contributes 50 percent of the composite score and the free response section (6 questions) contributes the remaining 50 percent. The composite is then converted to the 1–5 scale using College Board's annual conversion chart.
