1L classes are big (110 students). Outside of the building block classes (e.g. Con Law, Evidence, Corporations), the 2L and 3L classes are pretty small. 3L year I had a tax policy class with 10 people. A Supreme Court class with 14 people. A trial practice class with 6 people. And a 14th Amendment class with 20 people.
Academically, Georgetown has two huge advantages over most law schools: course offerings and location. Georgetown is a big law school. Because of its size, Georgetown offers a large and diverse schedule of courses. This means that there is something for everyone. This also means that there are quite a few specialty courses in darn near any area of the law that might interest someone. Georgetown's location in DC means that Georgetown can feature courses, professors, and speakers that no other school can. Many, if not most, Supreme Court advocates moot their cases at Georgetown's Supreme Court Institute in the weeks before their cases goes before the Supreme Court. Congressmen, Senators, and other political types are frequently on campus for speaking engagement - House Intelligence Select Committeemember Jane Harman was on a panel discussing national security; Arlen Spector spoke; GULC alum Patrick Leahy was there a few times; the Israeli Ambassador spoke; Alberto Gonzalez made some waves; etc.
I never saw, nor heard of, any instance of negative competitiveness at Georgetown. People there are smart. They will kick your butt academically if you are not working hard. At the same time, most people view law school as a cooperative learning environment - people share their notes, they help you out if you don't get something, they don't try to screw you over or hide books or anything.
Lastly, perhaps the best part of the Georgetown is the huge offering of clinical programs. I did a year-long clinic during my 2L year and another year-long clinic during my 3L year. They were fantastic. You can represent criminal defendants, you can help draft legislation, you can write briefs for the Court of Appeal for the District of Columbia Circuit, you can teach legal concept to high school students, you can work in family law, you can work in environmental law. Great selection and awesome experience.
Quality of Life
Living on campus was incredibly convenient - most especially because Georgetown has an absolutely fantastic on-campus fitness center with a weight room, basketball court, pool, racquetball court.
A dorm room is a dorm room to me. I lived in a triple. Good-sized kitchen. Two baths. Decent-sized room. Cable, wi-fi, all the good stuff. Over-priced (probably a $200/month premium for living on campus). With a little research, a person can get a better place in a cooler neighborhood for less.
Georgetown is not really in a neighborhood. Rather is sits in between Chinatown (cool) and Capital Hill (cool).
