@jauen2015, I am a solid math and science guy who had no desire (or ability!) to sing or act in high school. I did play in my school’s orchestra though so I guess I am a tad artsy, and I am a member of several varsity teams but am not a recruited athlete. One of the many things I like about Yale is that there’s room for everyone to participate and flourish. Did you get a chance to go to Yale’s Admitted Student Days (Bulldog Days)? Bulldog Days really helped me see how great the residential college system is at Yale and the pre-frosh I met were interesting, diverse, and friendly. I also thought that Old Campus was incredibly regal and beautiful, with so many things happenings that the negatives I’d heard about New Haven at night became non-issues.
I confess that I did tour Dartmouth earlier in the college app process and thought the campus pretty but, because it is isolated, I worried that the fraternity life is way too large a part of the culture so did not apply (I am open to pledging a fraternity, but I did not like the mandate that fun = fraternity that I felt at Dartmouth). Wherever you wind up will be the right place for you, and good luck over these next few days making your decision.
