If you’re preparing for an AP Calculus exam, you might be wondering what the differences are between AP Calculus AB and AP Calculus BC. Both courses cover the fundamentals of calculus, but they differ in depth, topics, and exam weighting. In this guide, I’ll walk you through the nature of each course, highlight the key topics, and break down the updated exam paper format. Let’s get started!
What Are AP Calculus AB and BC?
AP Calculus AB is designed to introduce you to the core concepts of calculus. It covers limits, derivatives, definite integrals, and the Fundamental Theorem of Calculus. Think of it as the equivalent of a first-semester college calculus course.
AP Calculus BC, on the other hand, includes all the topics in AB and goes further by delving into additional topics such as sequences and series, parametric equations, polar coordinates, and more advanced integration techniques. Many colleges consider BC to be equivalent to two semesters of calculus.
Detailed Syllabus Overview
The courses are organized around a few big ideas that form the backbone of the curriculum. The table below summarizes the major topics along with the approximate weightings for each unit, differentiated by AP Calculus AB and BC with updated format.
Unit/Big Idea | Topics Covered | Weight (AB) | Weight (BC) |
Unit 1: Limits and Continuity | Limits, one-sided limits, infinite limits, continuity, and the Intermediate Value Theorem. | 10–12% | 4–7% |
Unit 2: Differentiation – Basic Rules | Derivative definitions, product, quotient, and chain rules. | 10–12% | 4–7% |
Unit 3: Differentiation – Advanced Techniques | Composite, implicit, and inverse functions; applications of differentiation. | 9–13% | 4–7% |
Unit 4: Contextual Applications of Differentiation | Related rates, optimization, and modeling using derivatives. | 10–15% | 6–9% |
Unit 5: Analyzing Functions Using Derivatives | Graphical analysis, curve sketching, and using derivatives to analyze function behavior. | 15–18% | 8–11% |
Unit 6: Integration and Accumulation of Change | Definite integrals, Riemann sums, and applications of integration. | 17–20% | 17–20% |
Unit 7: Differential Equations | Solving basic differential equations and using them to model real-world scenarios. | 6–12% | 6–9% |
Unit 8: Applications of Integration | Area, volume, and accumulation applications using integrals. | 10–15% | 6–9% |
Unit 9: Parametric Equations, Polar Coordinates, & Vectors | (BC only) Analysis of curves defined parametrically or in polar form, and introduction to vector functions. | --- | 11–12% |
Unit 10: Infinite Sequences and Series | (BC only) Convergence tests, power series, Taylor and Maclaurin series, and approximation techniques. | --- | 17–18% |
Note: These percentages refer to the approximate weighting of topics in the multiple-choice section of the exam, based on the latest College Board Course and Exam Description.

Exam Paper Format: AB vs. BC
Both AP Calculus AB and BC exams are designed to assess your understanding through a blend of multiple-choice and free-response questions. However, there are some differences in the overall format and time allotment between the two exams. Here’s a side-by-side look:
Overall Exam Duration (Both AB and BC)
Total Testing Time: 3 hours and 15 minutes
Multiple-Choice Section
Section | Details | AP Calculus AB | AP Calculus BC |
Part A | Graphing calculator not permitted. Contains 30 questions. | 60 minutes; 33.3% | 60 minutes; 33.3% |
Part B | Graphing calculator required. Contains 15 questions. | 45 minutes; 16.7% | 45 minutes; 16.7% |
Total | Total: 45 multiple-choice questions. | 45 questions; 50% score | 45 questions; 50% score |
Free-Response Section
Section | Details | AP Calculus AB | AP Calculus BC |
Part A | Graphing calculator required. Contains 2 free-response questions. | 30 minutes; 16.7% | 30 minutes; 16.7% |
Part B | Graphing calculator not permitted. Contains 4 free-response questions. | 60 minutes; 33.3% | 60 minutes; 33.3% |
Total | Total: 6 free-response questions. | 6 questions; 50% score | 6 questions; 50% score |
Study Tips for Success
General Tips for Both AB and BC:
Master the Basics: Ensure you understand core concepts such as limits, differentiation, and integration.
Practice a Variety of Problems: Work through both conceptual questions and procedural problems.
Time Management: Practice under timed conditions so you can pace yourself during the exam.
Familiarize Yourself with Calculator Use: Especially for Part B of the multiple-choice section, know your graphing calculator well.
Review Past Exams: Use College Board-released materials to get a feel for the exam’s style and question formats.
Additional Tips for AP Calculus BC:
Focus on Advanced Topics: Since BC includes topics such as sequences, series, parametric equations, and polar coordinates, allocate extra study time for these areas.
Practice Series and Advanced Integration Techniques: Work on convergence tests, Taylor/Maclaurin series, and more complex integration methods.
Work on Multi-Part Problems: BC free-response questions can be more involved so practice breaking down complex problems into manageable steps.
Success on the Updated AP Calculus AB and BC Exams
The AP Calculus AB and BC exams are challenging, but with the right preparation and a clear understanding of what’s expected, you can excel. Whether you’re tackling the core topics in AB or the additional material in BC, a balanced approach combining conceptual understanding and practice is key. Remember to use the latest official resources, including the College Board website, to ensure your study materials are up-to-date.
Good luck on your AP Calculus journey! With dedication and consistent practice, you’ll be well-prepared to tackle any challenge the exam throws your way.
