The AP Calculus AB Exam: Your Guide to Success!

This expert guide to the AP Calculus AB Exam is designed to help you succeed on testing day. You’ll quickly find essential information about the AP Calculus AB Exam, including what’s on the exam, what’s weighted most, how long the exam takes, and what are the best ways to study and prepare.


The AP Calculus AB Exam: A Quick Overview

Advanced Placement (AP) courses are rigorous, college-level courses, with corresponding assessments. The courses are ones you'll find offered in many US high schools. Curricula and exams are governed by the College Board.

Doing well on AP assessments can translate to college credit in US and Canadian universities, and perhaps more importantly, can significantly elevate your university application profile, constituting a distinct marker of your ability to master rigorous academic content in core subject areas.

AP Calculus AB vs BC

AP Calculus is offered in two different course formats: AB and BC. The main difference between the two is that BC covers more content.

AB Calculus is equivalent to about one semester (or a bit more) of math concepts, while BC Calculus is designed to be the equivalent of a full year of calculus. Which one you take is largely a question of personal choice and circumstances...

For example, depending on your level of comfort with math, and/or out of consideration for other courses and commitments you have on your plate, it may simply make more sense to take the less ambitious AB course for one semester of college credit.

Alternately, of course, you may find taking the more comprehensive BC course a better fit, allowing you a chance to earn two semesters of college credit.

The AP Calculus AB Exam corresponds to material covered in AP Calculus AB curriculum only, which is devoted to the study of differential and integral calculus.

The course content for this exam is broken down into

  • 3 Big Ideas
  • 8 primary subtopics

The exam takes 3 hours and 15 minutes, not including breaks and administration time.

Are Calculators Allowed?

Yes. Students sitting for the exam are expected to bring a graphing calculator. The calculator is required for two sub-sections of the exam but not allowed on the alternate sub-sections.

Key Elements:

  • 45 Multiple Choice Questions (MSQ), counting for 50% of the total score
  • 6 Free Response Questions (FRQ), counting for the remaining 50% of the total score

With this overview in mind, let's delve into the core content covered on the exam and other essential information that will set you up for success when it's time to take your AP exam.

What's Covered on the AP Calculus AB Exam?

The knowledge and skills tested on the AP Calculus AB Exam revolve around 3 Big Ideas that capture the major themes guiding AP Calculus AB curriculum, what students learn when enrolled in the AP Calculus AB Course in high school.

The 3 Big Ideas for AP Calculus AB
BIG IDEA 1: CHANGEBIG IDEA 2: LIMITSBIG IDEA 3: ANALYSIS OF FUNCTIONS
Understand change by using derivatives to describe rates of change of one variable with respect to anotherUnderstand how to use calculus to model real-world behaviorUse calculus to analyze the behaviors of functions by relating limits to differentiation, integration, and infinite series
Understand change by using definite integrals to describe the net change in one variable over an interval of anotherUnderstand how to discover and understand important ideas, definitions, formulas, and theorems in calculusUse calculus to analyze the behaviors of functions by relating each of these concepts to the others

Calculus is broadly defined as the study of mathematical formulas used to model and calculate change, such as the physical motion of an object, including rates of deceleration or acceleration.

As such, calculus concepts can be understood not only theoretically, but offer many practical and essential applications you can use to stand out in STEM fields, such as engineering, physics, and chemistry.

With a high enough score on your AP test, you'll be able to move ahead faster in college in majors like these.

And, and even if you don't score well on an AP exam, taking any AP course is likely to be rewarding: helping you prep for success in college and elevating your skills and knowledge.

Tips For the Exam Day

1. Get a Good Night’s Rest

Let's start with the foundation — a good night's sleep. This isn't just a casual suggestion; it's a game-changer.

Your brain needs to be firing on all cylinders, and a well-rested you is more likely to tackle those AP physics challenges effectively.

Aim for 7–9 hours of sleep before exam day. Create a bedtime routine to wind down, avoid caffeine late in the day, and resist the urge to pull an all-nighter — it’s never worth it.

2. Deep Breaths and Mindfulness

As you enter the exam room, find your zen zone. Take a few deep breaths — in through the nose, out through the mouth. This isn't a cliche; deep breathing calms your nervous system, reducing anxiety.

Remind yourself that you've prepared for the AP Calculus AB Exam thoroughly. Read each question carefully, underlining key terms. This helps organize your thoughts and signals to your brain that you've got this under control.

3. Manage Your Time

Time management is your invisible companion in this AP test-taking adventure. Mastering time management and monitoring your time carefully during the exam is crucial — here’s how to do it:

  • Don't get stuck: If a question feels like quicksand, don't let it pull you under. Mark it, skip it, and revisit it later.
  • Be efficient: Use your mastery of the task verbs (listed above) and apply this as you're reading and interpreting exam questions. Don't let your mind wander: identify key terms, underline essential information, and focus on what's being asked.

4. Show Your Work

The College Board recommends you show your work — all the steps you took to reach your solutions on questions involving calculations. And remember, they want you to do this even when...

  • a calculator is allowed and you're using one
  • a question doesn't explicitly tell you to do so

Remember to write your work in standard notation (not calculator syntax).

Learn more about showing your work and check out additional testing day reminders and tips here.

5. Pack Smart

When packing your exam essentials, think like an organized physicist.

As mentioned above, you’ll need the right calculator, but you’ll need to pack a few other things too:

  • ID
  • Sharpened Pencils
  • Erasers
  • Water Bottle
  • Your laptop (when required for online/digital test formats)

Maybe a lucky charm too??... If it brings you comfort, toss it in!
