AP Calculus AB
AP Calculus courses span a full academic year of high school study and are equivalent to introductory college calculus. Students who enroll in an AP calculus course usually aim to earn college credit, advanced placement, or both.
The AP Program defines two distinct calculus courses, each with its own exam: Calculus AB and Calculus BC.
Any school that can build a curriculum for mathematically capable students may offer Calculus AB as an AP course. The program assumes students meet all the prerequisites for a yearlong calculus course (listed on page 6). While some class time can be spent reviewing elementary functions, the majority of the year should be devoted to the differential and integral calculus topics outlined on pages 6 to 9. Those topics form the core of the AP Exam.
Calculus BC is an option for schools where students complete the prerequisites on page 6 before the course begins. It is a full-year course covering single-variable calculus, including all Calculus AB material plus additional content. Both courses demand a high level of understanding; the common topics require similar depth. The BC course description spans pages 9 to 12. On the Calculus BC Exam, a Calculus AB subscore is calculated based on performance on the AB-related portion.
Both Calculus AB and BC represent college-level mathematics, and most institutions award advanced placement and/or credit for them. Colleges and universities usually offer a sequence of calculus courses, and incoming students are placed according to their preparation—often measured by AP Exam scores or other criteria. Each school sets its own credit and placement policies. Calculus BC prepares students for placement and credit one course beyond the level granted for Calculus AB. Many colleges publish their AP policies in catalogs and online.
High schools have several options for implementing AP Calculus. The best choice depends on local factors such as school size, curriculum, teacher preparation, and the interests of students, faculty, and administrators.
Strong performance in AP Calculus is closely linked to prior preparation. Before attempting calculus, students should have thoroughly mastered material equivalent to four full years of high school mathematics. These years should cover algebra, geometry, coordinate geometry, and trigonometry, with the fourth year focusing on advanced topics in algebra, trigonometry, analytic geometry, and elementary functions. Schools may achieve this through various pathways—including starting high school math in 8th grade, doubling up on math courses in grades 9–11, or offering summer study or guided independent study. However, skipping essential preparatory coursework to rush into an AP course is not appropriate.
The AP Calculus Development Committee recommends that calculus be taught as a college-level course. With a solid foundation from earlier courses, students will be ready for the rigor of this level. Those who take an AP Calculus course should do so with the goal of placing out of a comparable college course, whether through the AP Exam, a college placement test, or another method the college accepts.
