In all seriousness, IMO, a BS student will not be disadvantaged by not taking AP’s or taking fewer AP’s. AP scores carry little to no weight in the admissions process, being used primarily for course credit and/or placement.
At my school, and I think @ChoatieMom can vouch for Choate, if the college counselors felt AP’s were important for admissions, they would be pushing them. At least in my case, I cannot recall even having a conversation about AP’s with him.
What grade is your son in? His interests and desires as a freshman/sophomore, as well as what courses would even be appropriate to take AP exams for, will vary dramatically compared to when he is a junior/senior.
