Grad school in minor area

I think for him to do that kind of double major he’d need for his AP classes to get him out of some general Ed requirements. He met with someone from the math department during our last college visit and was told he’d have a jump on most of the other students due to the math courses he will have had already (II know very little about math, but I thought I heard “Calculus 3”). I have a feeling this will all work itself out.
