You can also go to the lesser crosstown rival: USC. By lesser I am talking primarily in terms of Football. (Who won the last game ?

). If you are a basketball fan, UCLA has the #1 bball team. We're on the quest for our 100th NCAA championship, so sports and sporting events are good.
As for USC, I would say without a doubt the social life ON CAMPUS is better. UCLA seems very clique-EeeeEEEEEEEEE. VERY.
If i were to do undergrad over, I would probably select USC; everyone parties together and basically that is why they are pretty good at business school (UCLA is a top 10, whereas USC is top 20- BUT, I just feel that USC you make more connections getting trashed with each other. Everyone seems to have lots of pride and very spirited.
UCLA: School city, Westwood (city in the Greater Los Angeles area) is sick. absolutely awesome. Everything upscale. Neighboring cities(Brentwood) and Beverly Hills. All UPSCALE.
USC is, comparatively, in the GHETTO. But, seriously, the girls are friendlier and hotter. Everytime I've been in the USC gym, I have gotten approached. EVERYTIME. Everyone seems just to be in a damn good mood at that school. That just doesn't happen at UCLA.
There is SO MUCH in Los Angeles. Everyone comes to hollywood to get big. Like style said, Beauty is common in LA. Shopping, Bars, Restaurants, clubs, you have it all here. The beach is a stone's throw away.
UCLA is ranked higher and is harder to get into, but for social life I would choose USC anyday.
