As a male poster my viewpoint on this subject has limited credibility. That being stated, Mount Holyoke women are nice & Barnard offers you NYC & Columbia. Smith should create an instant impression as to whether or not it is the right fit for you. You need to visit. If it fits, you can explore four other schools as desired. Scripps is a great option because of the Claremont Consortium schools & my impression is that it is considered more mainstream than Smith.
Wellesley College should be considered. I think that there are frequent mixers with MIT students.
All are high IQ schools.
