AP Calculus AB vs BC: Which Should You Take?

The single most-asked AP math question: should I take AB or BC? Here's the honest answer based on content scope, difficulty, college credit value, and your major.

Content Difference

• AP Calc AB covers limits, derivatives, integrals, and the fundamental theorem of calculus. Roughly the first semester of college Calc.
• AP Calc BC covers all of AB plus parametric equations, polar coordinates, vector functions, sequences, and series (Taylor series, convergence tests). Roughly the first two semesters of college Calc.

Difficulty

• AB: 64% pass rate, 22% 5-rate. Manageable for strong precalc students.
• BC: 79% pass rate, 45% 5-rate. Higher rates because of self-selection — only confident students take it.

Don't be fooled by pass rates: BC content is genuinely harder. The high rates reflect strong students, not easy material.

College Credit

• AB: One semester of college calculus credit at most schools.
• BC: Two semesters of credit at most schools (often Calc I + II). BC also reports an "AB subscore" so you can earn AB credit if you don't score high enough for BC credit.

Who Should Take Each

• Take AB if: You're a STEM major who needs Calc credit but doesn't need to rush through college calc. Or you struggled in precalc and want to build confidence.
• Take BC if: You're strong in math, planning engineering / CS / physics / pure math, and want to skip Calc II in college. The series content matters for these majors.
• Take BC instead of AB if your school offers both: The AB subscore protects your downside. Take the harder one and earn AB credit even if BC doesn't quite work out.
