AP Calculus AB vs BC: Which Should You Take and How to Prepare?

Let's be real – choosing between AP Calculus AB or AP Calculus BC feels like it could define your entire junior or senior year. It’s the classic high school dilemma.

Here’s what I’ve come to realize: we’re all so focused on which class is harder that we’re asking the wrong question. The truth is, the best choice isn't a choice at all—it's a fit.

After talking to high schoolers and guidance counselors, I've realized you just need to honestly answer three questions to get this right:

1. Your Future Goals: What's your intended major, and how competitive are your target colleges?
2. The Credit Game: What do those colleges actually give you credit for?
3. Your Math Skills: How quickly do you learn math, not just how good you are at it?

Do You Take AP Calculus AB Before BC? One Course or Two Different Paths?

The single biggest misunderstanding I found is that AB and BC are sequential courses—that you take AB one year and BC the next.

This is incorrect. The CollegeBoard did not design them to be taken back-to-back.

Think of it this way:

• AP Calculus AB is a full-year course that covers the first semester of college calculus (Calculus I).
• AP Calculus BC is a full-year course that covers both the first and second semesters of college calculus (Calculus I and II).

This means AP Calculus BC includes 100% of the AB curriculum, plus new, more advanced topics. A student is meant to take either AB or BC.

Are AP Calculus BC Scores Higher? Does That Mean It's Easier?

This is the first thing I researched, because the data looks quite strange. When you look at the 2024 score distributions, you will see something that confuses a lot of students and parents:

What Are the Actual Prerequisites for AP Calculus AB and BC?

Here’s where I had to do some research, because the official answer is misleading.

• Officially, the College Board lists the same requirements for both AP Calculus AB and BC, and they are quite general.
• They recommend that you've successfully finished courses in algebra, geometry, trigonometry, analytic geometry, and elementary functions.
• But for AP Calculus BC, students are specifically expected to understand sequences, series, and polar equations. These are topics taught in an advanced or Honors Pre-Calculus class.
• Some very competitive high schools might raise the bar even higher, demanding a 95% in Honors Pre-Calculus just to be considered for the BC class.

This shows that schools see AP Calculus BC as a class meant only for students who have already proven they are very strong in math.

Which AP Calculus is Right for Your Major?

This is the most important part of my research. Your choice sends a signal to colleges. Here’s how to align your choice with your academic and career goals.

🧪 STEM (Engineering, Computer Science, Physics)

For top-tier universities (e.g., MIT, Carnegie Mellon, Caltech, Berkeley-EECS), taking AP Calculus BC (if offered) is not a bonus; it is an expectation. For a competitive CS or engineering program, choosing AP Calculus AB when BC is available can be viewed as not rigorous.

These majors will all require Calculus I and II, and often Calculus III (Multivariable) and Linear Algebra.

💲Business and Economics

I found that for many business majors (e.g., Management, Marketing) will only require a Business Calculus or brief Calculus course in college, which is often less rigorous than Calculus I. AP Calculus AB is more than sufficient to earn credit for this and is a good choice.

Quantitative Finance/Economics degrees (especially for students considering a Ph.D.) are extremely math-heavy. For these programs, AP Calculus BC is almost the expectation. Advanced economics uses concepts from Calculus I, II, and multivariable calculus.

🏥 Life Sciences and Pre-Medical

Pre-med and life science majors (Biology, Neuroscience, etc.) typically require one semester of calculus (Calculus I), for which AP Calculus AB is a perfect fit.

AP Statistics is arguably as important, or more important, than the Calculus II topics in AP Calculus BC. Medical research and biology is heavily dependent on data analysis.

🎨 Literature and Arts

For students majoring in English, History, Political Science, or other humanities, the goal is twofold: satisfy a core university math requirement and demonstrate quantitative rigor on a college application.

AP Calculus AB achieves both of these goals perfectly. It is a rigorous, respected course, but its moderate pace makes it a manageable part of a schedule that may be heavily loaded with reading- and writing-intensive APs (e.g., AP English Literature, AP U.S. History).

What Top Colleges Recommend - AP Calculus AB or BC?

I put together this table based on all the college sites and forums I reviewed. It simplifies the recommendations at a glance.

AP Calculus Credit: Why a 5 at MIT is Different Than at UC?

This is the #1 mistake I see students make. They assume getting a good score automatically gets them credit.

The reality? Every single school is different. And the policy often changes by program (e.g., Engineering vs. Arts & Sciences).

The General Rule:

• Pass AB (Score 3–5) -> Get credit for one semester (Calculus I).
• Pass BC (Score 4–5) -> Get credit for two semesters (Calculus I & II).

The Reality: Every single school is different. And the policy often changes by program (e.g., Engineering vs. Arts & Sciences).

I compiled these examples just to show you how wild the differences are:

The Bottom Line: Do not guess. You must go to the website of every college you are interested in, find their AP Credit Policy, and check the specific rules for your intended major.

How to Prepare for AP Calculus AB and BC?

To prepare for either exam, you will need a regular study schedule and the right resources. Start by taking a ‘Calculus Readiness Test’ to see where you stand with essential skills like algebra, functions, and trigonometry; even colleges like Duke use these to ensure students have mastered precalculus.

Once you are ready, the best official practice comes from the College Board's website, which has years of old FRQs with scoring guides.
