I’ll suggest Indiana University. Their Hamilton Lugar School of Global and International Studies is well regarded. Overall they have an 80% acceptance rate for out of state applicants, which is higher than their in state acceptance rate. So, they seem to like bringing in out of state students. Her ACT score is in their top quartile and they place importance on standardized test scores, right behind gpa and class rank. Her gpa is not strong, as you know, but with their high acceptance rate and strong ACT, I think that she stands a good chance of acceptance for the Lugar School.
IU is in Bloomington, IN, which shows up frequently on ratings of best college towns in the country. I know one student from New England who is a sophomore there in International Relations and is very happy with her decision.
