My high school did exactly that in the 2000s. The local Community College teacher drove to the high school and taught a class. You got high school credit and college credit if you payed the $50 community College enrollment. No ap test required.
Students could also take additional ge's at college outside of school hours, and I entered University with about 80 credits
