This article says it all. Especially this paragraph:
Perhaps I should explain why I chose to go to a women’s college. I applied and was accepted into both co-ed and single-sex schools. I ultimately chose to go to a women’s college because I was amazed by the strong community I found there and the notable accomplishments of previous graduates. Clearly, women’s colleges prepare women well for the world and encourage them to be passionate about what they choose to do. Of course, I understand that a same-sex college is not necessarily appropriate for every woman, but I do believe there are great advantages to attending one, if the college is a good fit.
That is exactly the reason I chose to apply to so many women’s colleges, and why I ultimately chose Smith. The women that graduate from these colleges are strong, independent, and fearless, traits that I strive to embody.
