A huge thank you to @TrackGuyUSA for donating a pair of throwing shoes and a pair of sprinter spikes to our Liberty Girls Track athletes! Your support gives our athletes the tools they need to compete and grow. We truly appreciate your generosity and commitment to our program. 🏃‍♀️

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:
https://t.co/R29IFEEUUX

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.
