The CC by UCF (Valencia) is pretty far from the UCF campus - in fact they actually have several campuses. Transportation would definitely be an issue although their are apartments nearby the East Campus and Lake Nona Campus.
If you want to go to one of the Florida Universities, you’ll probably have much better luck at UNF, FAU, FIU, FGCU, or FAMU. If you’re considering med school, I’d say take a good look at FIU. They have a med school and I believe that students in their Honors College can apply for early decision. You won’t qualify for their Honors program as a freshman, but if you do well your freshman year I believe you can apply based on your freshman grades.
