It definitely sucks that the satellite campuses have less seating for students. I'm sorry you're dealing with that. I am pretty sure people in my first small group were pulled off the waitlist even into June or July. Just because you didn't hear in May doesn't mean you're never going to come off.
I know it is hard to keep hope at times like these, but don't lose faith. I agree with ProudFather94 on the fact that you have shown so much dedication to the school and they would be very lucky to have you.
If you ranked both C & A, there's still potential for you to be accepted into the Athens campus. On my original app I ranked D then A so I had the potential to go to either place off the waitlist. You might be able to discuss with them that you also want to go to Athens?
However, if you're dead set on C, then I really hope it happens for you this cycle. But if you have to wait until next cycle, I think they will look more favorably on you reapplying since it shows so much dedication to the school. Have you asked for a tour?
