If you attend a school such as, say, Wesleyan, it would be challenging to find a college to which you could transfer that would offer a greater, or even a similar, academic level and range of opportunities. However, you’ve expressed a desire for an urban campus atmosphere and a well-developed urban studies program, aspects either missing or insufficient for you at your current school. My strongest recommendation would be that you reapply to Barnard, which, with a fairly accommodating 22% acceptance rate for transfer applicants, might welcome your continued interest.
