The 2025 AP Precalculus Exam scores:
5: 28%; 4: 26%; 3: 27%; 2: 11%; 1: 8%

The common-item equating psychometricians use to gauge changes in student mastery year over year found that this year’s AP Precalculus students had higher content mastery than last year’s, resulting in an overall increase of ~3% in students scoring a 5, part of an overall 5% increase in scores of 3+. AP Precalculus grew more significantly than any AP subject this year, with ~70,000 more students participating than in 2024. An increased volume in participation and higher content mastery means more students are accessing higher level math and are positioning themselves for future success. In part, these impressive scores reflect the far larger number of instructional hours that precalculus courses typically provide high school students, in contrast to the hours provided such students in college, where this is generally a one-semester class. Many of these excellent students will enter colleges and majors that consider precalculus “advanced math” and will thus allow this AP credit to fulfill their college math requirement; for others who attend colleges or enroll in majors that require calculus, it’s great to see this strong preparation for further advanced mathematics.

AP Precalculus Multiple-Choice Questions:

Overall, students performed well across most function types. General Functions (non-analytical) stood out, with 53% of students earning all or most of the available points on these questions.

In contrast, Trigonometric and Polar Functions proved most challenging: 20% of students earned all or most of the available points on these questions. This is a good instructional focus next year.

AP Precalculus Free-Response Questions:

Students performed best on Question 1 (Function Concepts), whereas Question 3 (Modeling a Periodic Context) was the single best question on this year’s exam, psychometrically, since it had the best mix of difficulty levels across the 6 points available. Students who can earn just 1 point are typically receiving an AP 1 overall; students who can earn 2 points are typically receiving an AP 2, overall, and students earning 5-6 points are typically receiving an AP 5, overall.

Question 4 (Symbolic Manipulations) was the most difficult, and served to differentiate the 3s, 4s, and 5s, as starting this question requires an understanding of algebraic manipulation that is beyond the proficiency of students who receive 1s and 2s. Students able to begin this question successfully are generally receiving an AP 3, and those able to earn multiple points on it receive 4s and 5s.

The 2025 AP Calculus AB Exam scores:
5: 20%; 4: 29%; 3: 15%; 2: 23%; 1: 13%

Multiple-Choice Questions

AP Calculus AB students scored highest on questions related to Unit 2: Differentiation: Definition and Fundamental Properties. 50% of students answered all or all but one of these questions right.

The most challenging questions were from Unit 6: Integration and Accumulation of Change. 7% of students answered correctly all or all but one of these questions.

Students generally scored highest on Q3, in which they modeled reading rates for a student and a teacher. And this was the best question, psychometrically, of the exam, since its points varied significantly in difficulty, enabling good measurement of student abilities across the 1-5 AP scale. The question was worth 9 points total, and students unable to answer at least 2 of those points correctly are generally receiving AP 1s and 2s, while students who could answer 8-9 of the points are typically receiving AP 5s.

The most challenging FRQ for AB students was Q1, the modeling of an invasive plant species’ spread within a fruit grove. (Who says farmers don’t need calculus?) Students earning 6-9 points on this question tended to receive AP 5s. Writing justifications for global maxima and minima is a good instructional focus for next year.

The 2025 AP Calculus BC Exam scores:
5: 44%; 4: 22%; 3: 13%; 2: 15%; 1: 6%

Multiple-Choice Questions

As is typical, Calculus BC students scored extremely well across the units that are shared with Calculus AB, especially Unit 1, where 55% of students answered every question right, and Units 2-3, where 41% did so.

The most challenging Calculus BC questions were from Units 9 and 10, which don’t overlap with Calculus AB. As usual, students found questions about infinite sequences and series most difficult: 4% answered all of these questions right.

Free-Response Questions
https://t.co/7hlTwOiKxj

Setting aside the three FRQs shared with Calculus AB, which Calc BC students typically find easier than the BC-specific FRQs, students scored highest on Q5, the differential equation question that requires understanding of the second-degree Taylor polynomial, the Lagrange error bound, and Euler’s method.

By far the most difficult question on this year’s BC exam was Q2, polar area, which served to differentiate among BC students, who are qualifying for AP 4s and 5s. Polar area is a good instructional focus for next year.
