How long is the AP Calc BC exam?
The AP Calculus BC exam is 3 hours and 10 minutes long, the same as AP Calculus AB. Section I has 42 multiple-choice questions in 1 hour 40 minutes, and Section II has 6 free-response questions in 1 hour 30 minutes. Each section counts for 50% of your score. In 2027 the exam is on Monday, May 10, in the morning session.
In more detail
Both sections are split by calculator use. Multiple-choice Part A is 29 questions in 62 minutes with no calculator, about 2 minutes each. Part B is 13 questions in 38 minutes, with a graphing calculator required for some, just under 3 minutes each. Free-response Part A is 2 problems in 30 minutes with a graphing calculator, and Part B is 4 problems in 60 minutes with none, so about 15 minutes per problem in both.
BC runs on the same clock as AB but covers more. On top of the AB units it adds parametric equations, polar coordinates and vector-valued functions, and infinite sequences and series. The extra topics do not buy extra time, so BC rewards speed on the shared calculus you already know.
In 2027 Calculus BC is in Session 1 on Monday, May 10, the same slot as Calculus AB, so you sit one or the other. Session 1 is typically the morning, and for most schools exams start at 8 a.m. local time. Check-in and instructions come on top, and approved accommodations such as extended time make the sitting longer.

Step by step
- 1
Take one full practice exam in one sitting: 100 minutes of multiple choice, then 90 minutes of free response.
- 2
Pace multiple-choice Part A at about 2 minutes per question without a calculator, and Part B at just under 3 minutes.
- 3
Practice the calculator parts with the same graphing calculator you will bring, and learn its graphing, table, root-finding and numerical integration functions.
- 4
Drill the BC-only topics, series and parametric and polar problems, under a timer, since they are where BC students lose the most minutes.
- 5
Give each free-response problem about 15 minutes, and write out the setup, justification and notation it asks for.
- 6
Score your answers with the official scoring guidelines and review the units behind your misses.

Is the AP Calculus BC exam longer than AB?
No. The College Board lists the same 3 hours 10 minutes for both, with 42 multiple-choice questions and 6 free-response questions.
Can you use a calculator on the AP Calculus BC exam?
Only on some parts. A graphing calculator is not allowed in multiple-choice Part A or free-response Part B, and it is required for some questions in multiple-choice Part B and in free-response Part A.
