Thanks SFwarrior25, best of luck to you with your application and your admittance.
Knights09, that's true, but from what I've heard USC is big on growth. I did horrible on my APs my junior year, but I definetly improved my senior year (self-studied Psych).
I've talked to my honors counselor at my CC (who has seen my HS transcript, and AP scores) and she thinks that I have a really good shot.
Anyways, thanks for your input you guys. I'm thinking that my best option, in terms of the ACT, is to wait until next year to take it (assuming I don't get into USC for this upcoming fall), that way I can show my score to USC and the UCs for fall '11.
