Should You Take AP Calculus AB or AP Calculus BC?

Introduction

For high school students who are planning their academic paths, deciding between AP Calculus AB and AP Calculus BC can seem like a big deal. Both classes are at the college level and cover advanced math topics, but they are not the same.

If you want to know things like:

  • What's the difference between AP Calculus AB and AP Calculus BC?
  • Which class is more difficult?
  • If you want to know if colleges will prefer AB or BC, this guide is for you.
We'll explain the differences in the syllabus, the format of the tests, the scores, the level of difficulty, and the benefits of going to college so you can make an informed decision.

What are the AP Calculus AB and AP Calculus BC tests?

  • AP Calculus AB
  • It is the same as a college calculus class in the first semester.
  • It talks about limits, derivatives, integrals, and simple differential equations.
  • There are 8 units of material.
  • AP Calculus BC
  • Two semesters of college calculus are the same as this.
  • Includes everything in AB as well as new topics like polar functions, parametric equations, and infinite series.
  • It has 12 units of material.
To put it simply, AB is the same as Calculus I and BC is the same a Calculus I and II at most colleges.

AP Calculus AB vs BC: Key Differences

Detailed Topic Comparison

  • Topics in Both AB and BC
  • Limits and continuity
  • Differentiation rules and applications
  • Integration (definite/indefinite)
  • Fundamental Theorem of Calculus
  • Differential equations (basic)
  • Applications of integrals (area, volume, motion)

  • Exclusive to BC
  • Polar coordinates → Graphs, area in polar coordinates.
  • Parametric equations → Derivatives and integrals of parametric curves.
  • Vector functions → Position, velocity, and acceleration in 2D/3D.
  • Infinite series → Convergence tests, Taylor/Maclaurin series, power series.
  • If you want exposure to advanced calculus concepts early, BC is the way to go.

AP Calculus AB vs. BC: How the Test Works

Both tests last for 3 hours and 15 minutes and are set up the same way:

  • Part I: Multiple Choice (50% of the score)
  • Part A: 30 questions, 60 minutes, no calculator.
  • Part B: 15 questions, 45 minutes, and a calculator are okay.

  • Part II: Free Response (50% of the score)
  • Part A: You have 30 minutes to answer 2 questions. You can use a calculator
  • Part B: 60 minutes, 4 questions, no calculator.
  • The BC exam is harder because the questions are about more advanced topics, but the format is the same.

Which test is harder?

  • AP Calculus AB → Less topics, slower pace. Great for students who want to build a strong base.
  • AP Calculus BC covers everything AB does in less time and adds more units. You need to be good at algebra, trigonometry, and pre-calculus to keep up.

Rates of Passing (2024 College Board Data):

  • About 58% of students who took AP Calculus AB got a 3 or higher.
  • About 81% of people who took AP Calculus BC got a 3 or higher.
  • It's surprising that BC has a higher pass rate because the students who take it are usually very well prepared.

Which Course Do Colleges Prefer?

  • Colleges respect both AB and BC. But:
  • STEM majors (engineering, physics, computer science, data science) → BC is better because it shows you're ready for higher-level math.
  • AB is usually enough for non-STEM majors. For liberal arts, economics, or business majors, many colleges only require AB-level calculus.
  • Credit Benefit:
  • If you get a 5 in AB, you can often get credit for one semester of college calculus.
  • If you get a 5 on the BC test, you might get credit for two semesters (Calc I and II).
  • If your dream college gives a lot of credit for BC, it could save you a whole semester's worth of tuition.

Should you take AP Calculus AB or AP Calculus BC?

Here's how to make a choice:

If you want to take AP Calculus AB

You want a math course that isn't too hard for college. You aren't completely sure about your algebra and trigonometry skills. You don't need advanced math for the college major you want.

If you want to take AP Calculus BC

You want to major in something related to STEM. You like math and want to be challenged. You already know a lot about pre-calculus. You might want to skip two semesters of college math.

Real Insights from Students

  • Students in AB: A lot of people say that the slower pace helped them feel more sure of themselves. They had more time to go over and understand each idea.
  • BC Students: They say it's fast-paced but worth it. They felt ready for advanced college math by the time they graduated from high school.

Tips for Studying for Both Classes

  • Stay consistent: Do practice problems every day.
  • You need to know how to do derivatives and integrals because they show up on both tests.
  • Don't use calculators to practice. At least half of the test is not with calculators.
  • Use FRQs from Old Tests—Free-response questions are very important.
  • Know how you learn best. If you need more time, AB might be better for you. If you like a challenge, BC will give you more of one.
