How Is the AP Calculus AB Exam Score Calculated?

The AP Calculus AB exam is scored on a 1 to 5 scale, but your final score is based on a composite score that combines performance from two sections:

  • Multiple Choice (Section I): 45 questions
  • Free Response (Section II): 6 problems

Each section is weighted equally (50%), and your raw scores from both are converted into a composite score, which is then mapped to the 1-5 scale.

What Is the Weight of Multiple-Choice Questions in the Final Score?

Multiple-choice questions make up 50% of your final score. There are 30 no-calculator questions and 15 calculator-allowed questions, each worth one point. Your raw score out of 45 is scaled to half of your total composite score.

How Do Free-Response Questions Contribute to the Composite Score?

The six free-response questions make up the remaining 50% of your total score:

  • 4 are regular FRQs
  • 2 are “multi-part” questions (more in-depth problems)

Each FRQ is worth 9 points, totaling 54 raw points. However, these responses are hand-graded and require well-organized reasoning and use of proper mathematical notation.

What Is a Good Score on the AP Calculus AB Exam?

A score of 3 or higher is considered “passing” and may qualify you for college credit.

Here’s a general breakdown:

AP Score Meaning Interpretation
5 Extremely well qualified Often earns full credit at top universities
4 Well qualified Usually accepted for credit or placement
3 Qualified May earn credit, especially at public colleges
2 Possibly qualified No credit, but you completed the course
1 No recommendation No credit or placement offered

What Score Is Typically Needed for College Credit?

Most colleges award credit for a 3 or higher, but the details vary.

Examples:

  • University of California–Berkeley: Accepts a 4 or 5 for Calculus AB (gets you into Math 1A)
  • Florida State University: Accepts a 3 or higher for credit
  • Georgia Tech: Requires a 4+ for credit in MATH 1551
  • Harvard University: No credit for AP scores, but may use them for placement

Check your school’s AP Credit Policy using the official College Board search tool.

How Can the AP Calculus AB Score Calculator Help You?

How to Prepare for the AP Calculus AB Exam?

Preparation should start early and build gradually. Here’s what works best:

  • Professional help from Legacy Online School’s teachers
  • Review unit-by-unit using the AP Course Description
  • Practice released free-response questions from past exams
  • Take timed mock exams and score them using online calculators

“Do one unit on Khan Academy per week, watch EVERY video and do EVERY quiz. Take the end of unit test to score mastery on the whole unit. For the last 4 weeks, the first two-week period should be intensive MCQ practice problems, and the last two-week period should be intensive FRQ practice problems, following rubrics and scoring every point”

How Is AP Calculus AB Different from AP Calculus BC?

Major differences include:

Topic AB BC
Units ~8 ~10
Content Derivatives, integrals, limits, applications AB content + series, polar functions, more advanced integrals
College Equivalent Calc I Calc I + II
Score Credit Often one semester Often two semesters

If you’re planning to major in engineering, physics, or math, BC may give you more placement advantages—but AB is still highly respected.
