What Is AP Calculus BC?

AP Calculus BC builds on the principles introduced in AP Calculus AB. Below we’ll take a closer look at the wide range of topics you’ll encounter in this AP course. 

Course Content

AP Calculus BC is designed to provide students with a comprehensive understanding of calculus and its applications. The course covers all the topics included in AP Calculus AB, but it also goes beyond that to cover additional concepts such as infinite sequences and series, and parametric equations, polar coordinates, and vector-valued functions.


To enroll in AP Calculus BC, students should have completed Algebra II and Geometry courses, and be familiar with trigonometric functions and their properties. Students should also be familiar with the prerequisites needed for AP Calculus AB, as AP Calculus BC covers all the topics in AP Calculus AB.

Make sure to study the additional topics outlined earlier, as they are a significant part of the AP Calculus BC curriculum. The course is challenging but rewarding for students who are up to the task. Similar to AP Calculus AB, this course has its own exam that tests your understanding of concepts and problem-solving abilities.

AP Calculus AB vs. AP Calculus BC: What Is the Difference?

The main difference between AP Calculus AB and AP Calculus BC is the depth and breadth of the material they cover. AP Calculus AB focuses on the first semester of calculus (Calculus I), while AP Calculus BC covers both the first and second semesters or a full year of calculus (Calculus I and II combined).

In simpler terms, AP Calculus AB covers the basics of calculus, while AP Calculus BC takes those basics and adds more advanced concepts. 

So, if you take AP Calculus BC, you'll learn everything that's in AP Calculus AB, plus some extras like infinite sequences, series, parametric equations, polar coordinates, and vector-valued functions. 

Fundamental Similarities and Key Differences

Let's discuss the fundamental similarities and key differences between AP Calculus AB and AP Calculus BC:

Fundamental Similarities

  • Pre-calculus Prerequisite: Both AP Calculus AB and AP Calculus BC require students to have completed a pre-calculus course as a prerequisite.
  • Calculus I: Both courses cover the fundamentals of Calculus I, which is the introductory level of calculus.
  • Shared Topics: All the topics covered in AP Calculus AB are also included in AP Calculus BC. This means that if you study Calculus BC, you will cover everything taught in Calculus AB.

Key Differences

  • Course Duration: AP Calculus AB focuses solely on the first semester of calculus (Calculus I). In contrast, AP Calculus BC covers both the first and second semesters or a full year of calculus (Calculus I and II courses combined).
  • Additional Concepts: Calculus BC goes beyond Calculus AB by introducing additional mathematical concepts. These additional topics include infinite sequences and series, parametric equations, polar coordinates, and vector-valued functions.
  • Pace of Learning: Due to the inclusion of more advanced concepts, Calculus BC is generally a more fast-paced and challenging course compared to Calculus AB.
  • Specific Units: Calculus AB typically covers three main sections: functions, derivatives, and integrals. Calculus BC includes these units but also adds an extra unit that focuses on polynomial approximations, series of constants, and the Taylor series.

While both Calculus AB and Calculus BC cover the fundamentals of calculus, Calculus BC is a more comprehensive and advanced course that includes additional topics and is taught at a faster pace. It's important to choose the course that aligns with your mathematical interests and goals.
