Check the requirements of the school. My first daughter wants to be an Engineer and the AP test is used to place you in the specific freshman Calc 1 class at her first choice.
2nd daughter’s major has minimal math credit so she would take the AP credit and easily exceed the required math courses.
I took Calculus in high school but didn’t feel like I knew the material and got a C all year long. In college it clicked and it was an easy A.
Nothing wrong with getting an easy A.
