Wellesley has many famous graduates (you may have heard of Hillary Clinton!). It is an excellent college. You should Google the Common Data Set for Wellesley to get more info on the average test scores of applicants, percent of international students, # of students in different majors, etc. It is competitive for admission and also quite expensive. They are not need blind for international students, so if you aren’t able to pay, your odds of getting in are less (your stats would have to be very good in their applicant pool in that case). Someone interested in Econ and social justice would find many other students with the same interests there. They also have a strong alumni network.
