AP or DE?

They don’t offer DE at our HS, just AP. S17 went to college with 9 credits, middle son had 39, of which SUNY took 30, which was their max as my son had all 4’s and 5’s, so it wasn’t a matter of the score. By contrast, S17’s roommate, from a HS in our same state, has 60 DE credits and came in at junior level. I am a teeny bit jealous because it would have made S17’s life as a BFA student much easier. Although he couldn’t graduate sooner, he would have been able to pursue a double major or just take a bunch of classes he might enjoy.
