What is your overall opinion of this school?
Northwestern is very well-rounded. Many academic departments are strong on campus, though NU does suffer a bit from the "jack of all trades, master of none" syndrome. Chemistry, History, Psychology, Journalism, Film, Theatre and Economics seem especially strong however, along with Materials Science, Biomedical Engineering and Chemical Engineering for the more technically inclined. NU requires most of its students to complete a very broad and extensive set of liberal arts distribution requirements. This can be both a blessing and a curse, as the undecided types are exposed to a variety of classes and styles of thinking, whereas many students with strong interests in one are often feel distro requirements impede them from specializing early on.
Socially, there are many options at NU. Many students hit up frat parties on Friday and Saturday nights, however there are plenty of theatre and music events, guest speakers and just general dorm horseplay to keep those who don't want to party entertained. Chicago and Evanston also offer many diverse opportunities for fun, and Evanston provides many opportunities for students looking for a good meal with some friends after a week of dorm food. Most students aren't limited to "one" type of social activity, many will for instance go to a party then see a play, or eat dinner in Chicago but then come back and spend the night chatting with friends in a dorm hallway. People tend to be fairly friendly and most NU kids are rather social and open to many different forms of entertainment.
