What Makes the AP Calculus AB Exam Difficult?

First of all, the AP Calculus AB Exam is a standardized test. That alone makes it unlike most every test you have seen up to this point in school!

Standardized means that every student in the United States who takes the test must take exactly the same test under precisely the same conditions. This is why you must register for the test far in advance and take it at a pre-approved testing center on a specific date.

Format of the AP Calculus AB Exam

The test itself takes about 3 hours, but there is typically a break in between sections. There will be 45 multiple choice problems and six free response questions.

The multiple choice format is similar to that of an SAT or ACT (except that the questions are all about calculus).

Free response problems are broken down into multiple parts. In addition, you must show every step of your work for full credit.

As the name implies, this test is all about calculus! There are three Big Ideas from calculus on the AB test.

  1. Functions and Limits
  2. Differential Calculus (derivatives and their applications)
  3. Integral Calculus (integrals and their applications)
