ok.. this can be hard because you dont know a TON about the different schools etc etc.. well.. i would first look for info about the schools on their website/sdn interview feedback/student posts on here.. then i would pick a few things out that I liked about the school (lots of community involvement... new clinics... special curriculum etc etc) and focus on those aspects and tie them back to what i want in a dental school and how I think the school would be a good fit for me...
hope that helps
