AP® Calculus BC Course And Exam Description
AP® Calculus BC is a fullyear course for students wishing to pursue a career focused on mathematics or allied subjects requiring heavy math. This course is equivalent to Calculus I and II in college, and scoring well on the exam can help you skip both the college courses and move on to advanced ones. Since it is one of the most extensive AP courses, preparing for it requires a detailed study plan and thorough knowledge of the course content and materials.
This guide will give you an overview of the AP Calculus BC units, topics, and key concepts taught during the course. In addition to these, we will also discuss the essential prerequisites to excel in this course. By the end of this guide, you’ll understand how to begin preparing for your upcoming Calculus BC exams and what skills to focus on.
AP Calculus BC Units, Topics, and Key Concepts
Before you learn about the AP Calculus BC course curriculum, it is vital to know about the prerequisites required to approach this course. Having these requirements set up beforehand eases your way through the course. It also lets you decide if you are ready to take a mathheavy course like AP Calculus BC. We’ve listed the prerequisites for the Calculus BC course below:
 Algebra I
 Geometry
 Algebra II
 Precalculus
The concepts in these courses help you build a solid foundation in reasoning with algebraic symbols and working with algebraic structures. This aspect is crucial to mastering AP Calculus BC. Make sure your high school offers courses that cover all or some of these concepts to help you prepare for the challenges of AP Calculus BC.
With the prerequisites set up, let’s explore the course component. Like AP Calculus AB, the AP Calculus BC exam tests you on two components—the course content and mathematical practices. The course content combines two aspects: units and big ideas. The ten units in the AP Calculus BC curriculum revolve around three recurring themes. The College Board® labels these themes as “big ideas”. In the following section, let’s dive deeper into these big ideas in the following section.
AP Calculus BC’s Three Big Ideas
The AP Calculus BC units rely on three key elements, or big ideas, that form the basis for this course. Each of these elements is weaved into the course units as you advance through Calculus BC. Let’s take a look at the following big ideas: Big Idea 1: Change (CHA) Students can understand the concept of ‘change’ in a variety of contexts by using derivatives to describe rates of change of one variable with respect to another or definite integrals to describe the net change in one variable over an interval of another. It is essential to understand the link between integration and differentiation as represented in the Fundamental Theorem of Calculus. This forms the essence of the first Big Idea of Change (CHA).
 Big Idea 2: Limits (LIM)
Understanding essential calculus ideas, definitions, formulae, and theorems such as continuity, differentiation, and integration constitutes the second big idea of Limits (LIM).
 Differentiation: Defining the derivative of a function, estimating derivatives at a point, connecting differentiability and continuity, determining derivatives of constants, sums, differences, and constant multiples and trigonometric functions. You’ll also need to learn about composite, Implicit, and inverse Functions.

 Integration: Finding the average value of a function, applying accumulation functions, finding the area between curves of functions, and finding volumes from crosssections and revolutions. You’ll also need to study the Fundamental Theorem of Calculus, find antiderivatives and indefinite integrals, and integrate using substitutions.
 Big Idea 3: Analysis Of Functions (FUN) The third big idea of Analysis of Functions (FUN) enables you to understand and evaluate the behaviors of functions by relating limits to differentiation, integration, and infinite series and relating each of these concepts to the others.
The Ten Units of AP Calculus BC and Their Topics
The units feature the study material you will learn in your AP Calculus BC course. Although the curriculum for AP Calculus BC is similar to that of the AP Calculus AB course curriculum, BC contains two additional units (Units 9 and 10), plus some extra topics in Units 6 to 8. We’ll discuss these extra units in detail, but below is a table to give you an idea:Unit  Additional Topics in AP Calculus BC 

Unit 6  Additional techniques of Integration 
Unit 7  Euler’s method and logistic models with differential equations 
Unit 8  Arc length and distance traveled along a smooth curve 
Unit 9  Parametric equations, polar coordinates, and vectorvalued functions 
Unit 10  Infinite sequences and series

As you progress through this unit, you’ll learn how to determine change by justifying claims about limits and continuity through definitions, theorems, and properties.
