Yale: The Big Picture
The thing I love about Yale is how it covered all the bases: academically, socially, extracurricularly, and even institutionally, I would change almost nothing about the school, except the weather.
The Yale administration, in sharp contrast with most other schools, acts and is perceived by the students to be genuinely interested in student happiness and well-being. The administrators (President, Dean of college, other deans, etc.) are all well-regarded by students, and because of this the student body and administration work pretty well together at finding consensus solutions for problems as they crop up.
Yale Academic Life
Yale academics are awesome. Something that is notable is that at Yale, there are many students who sacrifice GPA for extracurricular activities that they love.
Yale's Student Body
Yale is very diverse, but like all Ivy League schools, it could still do a better job of socioeconomic diversity. I think that they should act affirmatively for parental income and education, in addition to acting affirmatively for race.
Yale Student Activities + Social Life
Only at Yale would the traditional Halloween activity be to get in costume, have a few drinks, and go to see the Yale Symphony Orchestra's midnight show in which they play a student-arranged soundtrack to a student-made movie in which the Yale Dean makes an appearance in a plaid skirt. Yale is AMAZING!
I love that my a cappella group was all the brotherhood of a fraternity, but based around singing instead of drinking.
