Multiple previous posters stated the obvious. Brown and Amherst are peer schools and among the very best in the world. The truth is that admission to either school is unlikely for an international student. No one can tell the applicant how much need blind or not will effect admission. It’s an unknowable variable. I only commented because the percent of students getting a PhD is not a good way to measure the quality of a school as the list shows. The only thing worse than getting a PhD is law school or vet school.
