If you take the AP Calculus BC Exam, you’ll get a Calculus AB subscore (1–5) in addition to your regular score. The Calculus AB subscore shows how you did on the part of the exam devoted to Calculus AB topics, which is approximately 60% of the exam.
The subscore gives colleges and universities more information about your abilities. We recommend to colleges that they treat the Calculus AB subscore on the Calculus BC Exam the same way they would treat an AP Calculus AB Exam score, since common topics are tested at the same conceptual level in both Calculus AB and Calculus BC. Of course, each college and university sets its own policy for awarding credit and/or placement for AP Exam scores.
Note: Subscores for the 2020 exams are not available. Due to their shorter duration, the 2020 AP Calculus BC Exams do not sufficiently assess the subsets of material required to calculate AB subscores in Calculus BC. However, this does not affect the calculation or validity of the AP Exam scores for the full exam in this course.
