Going back to the Calc AB exam format, let’s learn in detail about what each section looks like:

Section I: Multiple-Choice Questions (MCQs)

The first section consists of 45 MCQs. You need to pick the correct answer from the five choices for each question. These answer choices often appear similar, tricking the student into thinking there could be more than one possible correct answer. This section has two parts:

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
  • Differentiation and integration of algebraic, exponential,
    logarithmic, trigonometric, and general types of functions.
  • Analytical, graphical, tabular, and verbal types of representations.
  • Real-world contexts like position, velocity, and acceleration.

Section II: Free-Response Questions (FRQs)

The second section of your AP exam will assess you based on your analytical and problem-solving skills. In the Free-Response section, you will not be given any answer choices and will be required to solve the problems methodically to derive the answers. This section has two parts:

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
  • Various types of functions, function representations, a mix of
    procedural and conceptual tasks.
  • At least two questions will incorporate a real-world context
    or scenario that you’ll need to solve.

There are a total number of six FRQs in Section II, with each question carrying equal weight. The FRQ section requires you to write out the solutions and detailed steps by which you solved the problems.

Remember, partial credit is given for the steps followed to deduce the answer to each problem. It is recommended that you read through all the questions from this section at the start of the exam. Doing so will help you decide which ones to attempt first and which you wish to tackle later. It is ideal to spare 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 have a detailed understanding of 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 test you on.

Types of Questions in the AP Calculus AB Exam

As discussed above, the MCQ and the FRQ sections each carry 50% of the total exam weightage. These sections will test you on the eight units from the AP Calculus AB course, and each unit has an expected weightage in these two sections.

In the following passages, we’ll analyze the two sections of the AP Calc AB exam to learn about the topics you’ll be tested on and what these questions might look like. Cultivating a solid understanding of the pattern and the content of these questions is essential to achieving a high score on your exam.

Multiple-Choice 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 answer choices. Let’s now look at the units and topics you’ll be tested on 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 than other units like Unit 3. Considering this aspect will help you focus on these sections, and you can distribute your study plan accordingly based on the unit weights.

Now let’s move on to the Free-Response Section and learn how it tests you.

Free-Response Questions (FRQs)

The free-response questions on the AP Calc AB exam include a variety of topics across the units of the course. These questions require you to demonstrate the step-by-step processes you employed to solve a problem and derive its answer. As mentioned earlier, this section assesses your analytical and problem-solving skills. Since this section requires a detailed answering process, it is graded manually by AP instructors and college teachers called AP Readers.

As we mentioned earlier, the entire course content for AP Calculus AB is distributed across three ‘Big Ideas’ prescribed by the College Board. These Big Ideas weave across the eight units taught during your AP Calc AB class. If you’re curious to know more about these Big Ideas and course units, you can check out our in-depth article on AP Calculus AB Course and Exam Description.
