<p>An advantage of some women’s colleges is that some classes are women only and the dorms are women only, but otherwise since they’re part of a consortium, you’re not just with women. Barnard is just accross the street from Columbia, for instance, and you can take classes freely there; Bryn Mawr is in a consortium with Haverford, Swarthmore, and Penn; those are the two women’s colleges that are both women’s colleges and not just women’s colleges, but Smith and Mount Holyoke are in a consortium with Amherst, UMass, and Hampshire so even if it’s not as convenient as crossing the street, it’s still a very diverse environment, and, as previously mentioned, Wellesley has agreements with other Boston colleges (and it’s not like you’ll lack male college students in Boston.)
Rose Hulman is in Indiana and RPI in NY, so both are within your limits.
In North Carolina, you can try for some merit at UNC-A, UNC-W, or NCSU (UNC-CH is almost impossible to get into from OOS unless you have something unique like being a legacy or a recruited athlete… Also: need-based aid).</p>
