Smaller schools are often more willing evaluate you holistically, evaluating more than your GPA and test scores. And the vast majority of test-optional colleges are smaller schools. You need to know yourself as a learner. If you want to know your professors, that’s much easier to do at a smaller school. If you want discussion-based classes, they’re easy to find at smaller schools, but at larger schools (over 10,000) you might not have them until junior year. You can find Greek life, sports and rah-rah, and friends anywhere, but the academic experience, for which your parents are paying big bucks, will largely be determined by the size of the school.
