For my DDs, the taking of AP/dual credit from HS has/and will allow them to take classes and dig deeper into two disparate interests in college - one is English Lit and CE, for my younger DD -CS and visual art. Yes, they could both graduate in 3 years in their main focus of study but will take 4 with 18 hrs/semester to follow 2 different passions. Isn’t that what college is for to prepare for the future but also to expand yourself personally. Neither of my kids have gone to our state flagship because this was not allowed. Too many kids and not enough seats but at other schools they welcome it.
