One of the key differences between AP Calculus AB and BC is the pace of the course. AP Calculus BC covers the same concepts as AP Calculus AB, but it does so at a much faster pace. This means that students must be able to learn and apply new concepts quickly to keep up with the course material.

Key Differences Between AP Calculus AB and BC

AP Calculus AB and BC are courses offered by the College Board that teach students the fundamental principles of calculus. While both courses cover similar content, there are some key differences between them.

Limits

Limits are an essential concept in calculus. In AP Calculus AB, students learn how to evaluate limits, while in AP Calculus BC, they learn how to evaluate and manipulate limits. AP Calculus BC covers more advanced limit concepts, such as L’Hopital’s rule, which is not covered in AP Calculus AB.

Sequences

Sequences are a series of numbers that follow a pattern. In AP Calculus AB, students learn how to work with sequences, while in AP Calculus BC, they learn how to work with both sequences and series. AP Calculus BC covers more advanced topics, such as convergence and divergence of series.

Integration and Accumulation of Change

Integration is the process of finding the area under a curve, and accumulation of change is the process of finding the total change over some time.

In AP Calculus AB, students learn how to integrate using basic techniques, while in AP Calculus BC, they learn more advanced integration techniques such as partial fractions and trigonometric substitution.

Differentiation: Composite, Implicit, and Inverse Functions

Differentiation is the process of finding the rate of change of a function. In AP Calculus AB, students learn how to differentiate using basic techniques, while in AP Calculus BC, they learn more advanced differentiation techniques such as implicit differentiation and inverse functions.

Accumulation of Change

Accumulation of change is the process of finding the total change over some time. In AP Calculus AB, students learn how to find the accumulation of change using basic techniques, while in AP Calculus BC, they learn more advanced techniques such as differential equations.

Exam Structure and Scoring

The AP Calculus AB and BC exams are both three hours and 15 minutes long, with two sections: multiple-choice (50% of the score) and free-response (50%). 

The BC exam covers AB topics plus additional ones. For BC’s free-response, there’s one series question, one on parametric/polar/vector functions, and four on general topics. Scores range from 1 to 5, with 3 as the passing score the College Board sets. 

However, colleges may have their credit requirements. The BC exam maintains consistent formats, weights, and scoring guidelines yearly. 

The College Board offers detailed scoring guidelines for each free-response question to help students understand how their answers will be assessed.

College Credit and Placement

One of the main reasons students take AP Calculus AB or BC is to earn college credit and placement. Colleges and universities may award credit for AP exams based on the student’s score, which can help them save time and money in college.

AP Calculus AB and BC are college-level courses that cover different material. AP Calculus AB covers topics taught in the first semester of college calculus, while AP Calculus BC covers the first and second semesters. As a result, students who take AP Calculus BC may be able to skip the first semester of college calculus and start with the second semester.

Each college has policies regarding AP credit and placement, so students need to research the specific policies of the colleges they are interested in attending. Some colleges may require a particular score on the AP exam to earn credit, while others may only offer placement into higher-level courses.

In addition to earning college credit and placement, taking AP Calculus can demonstrate to colleges that a student is prepared for college-level work. This can be helpful when applying to colleges and universities, as it shows that the students are willing to challenge themselves and take rigorous courses.

Preparation and Prerequisites

To be successful in either AP Calculus AB or BC, students should have a strong foundation in math, particularly in algebra, geometry, trigonometry, and analytic geometry.

These topics are typically covered in earlier math courses such as Algebra II and pre-calculus. It is recommended that students take these courses before attempting either AP Calculus AB or BC.

In addition to these math courses, students should have a solid understanding of elementary functions such as polynomial, exponential, and logarithmic. Mastery of these functions will be essential for success in both AP Calculus AB and BC.

For students planning to take AP Calculus BC, it is essential to note that the course covers the same concepts and skills as AP Calculus AB but at a faster pace. As a result, students should be prepared to learn additional units and topics not covered in the AP Calculus AB curriculum.

Career Implications

Choosing between AP Calculus AB and BC can have significant career implications. Both courses can provide a strong foundation for students pursuing careers in STEM fields, including technology, engineering, and natural sciences.

Students who excel in AP Calculus AB may easily transition into college-level calculus courses. This is especially true for students pursuing STEM majors, as calculus is often a required course for these degrees.

However, students pursuing careers requiring advanced calculus knowledge, such as engineering or physics, may benefit more from taking AP Calculus BC.

In addition to preparing students for college-level calculus courses, AP Calculus BC can provide a competitive advantage in the job market.

Many employers in STEM fields look for candidates with strong calculus skills, and having AP Calculus BC on a resume can demonstrate that a candidate has a deep understanding of calculus concepts and can apply them to real-world problems.

Choosing Between AP Calculus AB and BC

When deciding between AP Calculus AB and BC, students should consider their strengths and interests in mathematics and their future academic and career goals.

AP Calculus AB covers limits, derivatives, and integrals, while AP Calculus BC covers those topics in addition to series, parametric equations, and polar functions. As a result, AP Calculus BC is a more rigorous and fast-paced course than AP Calculus AB.

Suppose a student is comfortable with the material covered in AP Calculus AB and is interested in pursuing a math-heavy field such as engineering or physics. In that case, they may benefit from taking AP Calculus BC to understand calculus concepts better.

However, if a student struggles with the material in AP Calculus AB or is not planning to pursue a math-heavy field, they may be better suited for AP Calculus AB.

It is also important to note that some colleges and universities may require or recommend a certain calculus level for admission or specific majors. Students should research the requirements of their desired schools and majors to help inform their decision.

Additionally, students should consider their performance on standardized tests such as the SAT or ACT. The math sections of these tests cover topics similar to those in AP Calculus AB, so students who perform well on these tests may be better suited for AP Calculus AB.
