Do you mean the two AP Physics C exams? (I haven’t heard of an AP Physics 3…)
Haven’t you already taken the Calc AB exam? Or was the score you listed in the original post a predicted score? Or do you mean Calc BC?
Colleges will not see your 12th grade AP exam scores, so the actual exams are only going to be useful for course credit and placement (if they even take these specific AP exams for credit and placement). But they would like to see you taking courses at your high school that are at least at the rigor level of these exams.
