I did a dual-enrollment program that was a normal ish 9th grade, and took college courses for 10-12th grade. Could see if there are similar programs in your area.
More generally, magnet or charter programs kinda select for people who are interested in the program (and in some cases people forced in by their parents), which could provide a better environment
Kinda? It was in South Florida, but it was a test-lab school kinda program.
My brother did an alternative where he could take some credits at the local CC, but it was still part of the standard high school experience. Seems a little closer to your experience in your other comment
There was definitely more camaraderie among the students in the program I did, mainly because of being all stuck together in 9th grade and how Everyone ended up taking classes at the uni (oftentimes together, since there's a lot of overlap in undergrad programs).
Yea, camaraderie would have been nice. Only 2 kids from my high school participated in the program. For financial reasons, I had to fully commit to college and couldn't do part time. Anyway, cool, I really liked the program and think it is a good option for some kids.
