Should I major in Philosophy for Law School or Something where I'd be more likely to get a high GPA?

[bluebayou]

But I thought that if someone was reviewing my app and saw Philosophy, even if my GPA was lower, that they’d prefer it over someone with a major in something else that most people at UCSD would consider easier.

Nope. GPA+LSAT is the ticked to nearly every law school. Get A’s, and lotsa of 'em. Any major will do.

btw: broaden your LS horizon; this is professional school, not undergrad where fit can be important. There is no “dream” school in Law, except for Yale. Moreover, with perhaps the exception of real estate, USC is no better than UCLA.
