i haven't really look at the programs from other states as much as i have at UNC, but it's something i would adapt well to.
the basketball team is great (although i'm not a big fan of sports b/c it's almost impossible to study on campus when there's a game), and the environment and social life is just as great. lot of liberals..
UNC is THE BEST school for me over harvard because it's my hometown, and i've grown to love. people here are relaxed, but also very professional. (i'm sure other schools are too, but i'm biased)
as far as the acceptances go, the rate of admission for out of state, i'd say, is relatively slim on the second round of admission unless those who are accepted all decided to go somewhere else. 12 candidates are accepted, and there are proabably 3 more slots left. (just doing random math here, so don't quote me on it).
for instaters such as myself, have about same probability or tad bit lower chance of admission (again, random math). but don't get your hopes down. once you're in school somewhere, you'll be happy because it's not all about school, but about dentistry.
i'd like to give you my best of wishes and luck!! at least you have a safety school now.
