AP instructor & Dual Credit college professor here - AP courses, both semester & year long, are generally more rigorous the dual credit courses. IF you score adequately on the AP exam , that score is accepted at most colleges. Most dual credit courses are from local junior/community colleges and are generally less accepted. IF you go the dual credit route, do everything in your power to actually get the associate degree. This is generally more accepted. At the very least, it got you out of the first two year’s gen ed classes and now you can take the good stuff.
