It's very difficult to make decision right now.
I love econ and chem ( not decided yet ~~)
However USC, I can pick up any major as I like and making more wealthy friends' not a bad thing.
UCLA, a nice school, famous but lots of students dun study seriously.
Mac, great chem/econ, but a lac limits my future ( I'm from China..)..BTW.. it's tooooo cold...
