If I had to go back in time, I would have only used AP credits to get out of classes not related to my major.
This exact situation for me, too.
My kid will take Calc AB or BC in 12th, but even though DC is leaning toward the idea of being a math major in college, will likely retake the college Calc sequence regardless of AP result. We’ve heard a lot of anecdotes about kids struggling when they place out of a course.
That said, I don’t think APs are a scam. As another pp noted, I just see them as the top-level rigor in whatever subject for HS, rather than as a replacement for a college class.
