Understanding the AP® Calculus AB Exam Format and Structure
Preparing for the AP® Calculus AB exam? Begin by familiarizing yourself with its format to plan your study effectively and avoid lastminute stress. This guide provides a comprehensive overview of the AP Calculus AB exam's format and structure, ensuring you're wellprepared and not caught offguard.
What is the Format of the AP Calculus AB Exam?
The AP Calculus AB exam is divided into two sections with a total duration of 3 hours and 15 minutes. Each section carries equal weight when the College Board® calculates your overall score. Here’s a table that summarizes how the AP Calculus AB exam is structured:
Section  Question Types  No. Of Questions  Time Per Section  Exam Weight 

Section I  MultipleChoice Questions (MCQs)  45  1 hour 45 mins  50% 
Section II  FreeResponse Questions (FRQs)  6  1 hour 30 mins  50% 
The overall score for the AP Calculus AB exam is calculated on a scale from 1 to 5, and a score of 3 or higher could potentially qualify you for advanced placement and/or college credit. Each college has its own specific set of requirements for AP credit, so make sure to check with your college to learn about their AP credit policy and regulations.
Going back to the AP Calc AB exam format, let’s learn in detail about what each section looks like:
Section I: MultipleChoice Questions (MCQs)
The first section consists of 45 multiplechoice questions (MCQs). For each question, you must pick the correct answer from a set of five choices. Be careful, as the answer options can be deceptive, making it seem like there could be more than one correct answer. This section has two parts:
SECTION I  Part A  Part B  

No. of Questions  30 MCQs  15 MCQs  
Exam Weight  33.3%  16.7%  
Time Allotted  1 hr  45 minutes  
Calculator Usage  Not Permitted  Permitted  
Question Types 

Section II: FreeResponse Questions (FRQs)
The second section of your AP exam will evaluate your analytical and problemsolving skills. In the FreeResponse section, you won’t have answer choices. Instead, you’ll need to solve the problems methodically to find the answers. This section also has two parts:
SECTION II  Part A  Part B  

No. of Questions  2 FRQs  4 FRQs  
Exam Weight  16.7%  33.3%  
Time Allotted  30 minutes  1 hr  
Calculator Usage  Permitted  Not Permitted  
Question Types 

There are six FRQs in Section II, with each question carrying equal weight. In this section, you must write out the solutions and detailed steps you took to solve the problems.
Remember, you’ll receive partial credit for the steps you follow to arrive at the answer for each problem. It’s a good idea to read through all the questions in this section at the beginning of the exam. Doing so will help you decide which ones to attempt first and which ones to leave for later. Aim to spend about 10–12 minutes on each question so that by the end of the exam, you’ll still have about 30 mins to tackle any difficult problems and revise your answers.
Now that you thoroughly understand the sections and the number of questions in the AP Calculus AB exam, let’s get into more detail and learn what these questions will assess.
Types of Questions in the AP Calculus AB Exam
As mentioned above, the MCQ and FRQ sections each carry 50% of the total exam score. These sections will test your knowledge of the eight units covered in the AP Calculus AB course, with each unit having a designated weight in both sections.
In the following paragraphs, we’ll examine the two sections of the AP Calc AB exam to familiarize ourselves with the topics that will be tested on and what these questions may entail. Developing a strong understanding of the question format and content is essential for achieving a high exam score.
MultipleChoice Questions (MCQs)
As you may already know, the MCQ section includes questions that come with four predetermined answer choices. You’ll have to analyze each problem and choose the correct answer from the four options. Let’s now look at the units and topics that will be tested and how each unit is weighted in the MCQ section.
Unit  Weight 

Unit 1: Limits and Continuity  10–12% 
Unit 2: Differentiation: Definition and Fundamental Properties  10–12% 
Unit 3: Differentiation: Composite, Implicit, and Inverse Functions  9–13% 
Unit 4: Contextual Applications of Differentiation  10–15% 
Unit 5: Analytical Applications of Differentiation  15–18% 
Unit 6: Integration and Accumulation of Change  17–20% 
Unit 7: Differential Equations  6–12% 
Unit 8: Applications of Integration  10–15% 
The units carrying higher weights will appear more often in the MCQ section. For example, you'll most likely get more questions from Unit 5 compared to other units, like Unit 3. Considering this will help you focus on these sections, allowing you to allocate your study time accordingly based on the unit weights.

Now, let’s move on to the freeresponse section and explore how it evaluates your understanding.
FreeResponse Questions (FRQs)
The freeresponse questions on the AP Calc AB exam cover various topics from the units in the course. These questions require you to show the stepbystep process you used to solve a problem and find the answer. As mentioned earlier, this section assesses your analytical and problemsolving skills. Since this section requires a detailed answering process, AP instructors and college teachers (AP Readers) manually grade this section.
As we mentioned before, the content for AP Calculus AB is divided into three ‘big ideas’ specified by the College Board. These big ideas weave through all eight units covered during AP Calc AB. If you’re interested in learning more about these big ideas and course units, you can check out our detailed article on the AP Calculus AB Course and Exam Description.
