In terms of prestige of undergrad schools, and premed curriculum/student body, Emory and UVA are equivalent. But if your a VA resident, and can get in state tuition, go to UVA for the lower cost. But you can't go wrong with either school. They are both excellent.
Also, be careful about your gpa once you transfer to either Emory or UVA. Not to knock your CC education thus far, but speaking from experience, both schools are pretty rigorous. Especially in pre-med classes. If your not 100% confident in getting A's in science classes at either UVA or Emory, don't bother. As most pple will tell you, grades are more important than prestige in med school admissions.
