It’s a good idea. I live in Florida and didn’t know it was possible. Of course, with the focus on AP classes in high school these days, it is probably similar.
In Polk County FL where the college is, the college has a program where high-ranking college students can go to PSC for the last two years of their high school, and graduate with both a HS diploma and an associate’s degree simultaneously; there are also options for students with high enough rank to schedule PSC courses around their high school requirements, in some cases taking everything online.
My community college experience, which ended about 13 years ago, was that the 16-17yo and the 25+yo were the diligent students, and the “traditional” students were more often than not incapable of handling a college-level curriculum.
