Chances of getting into USC?

It has been my dream to get into USC. Both my parents went their and I currently live with my dad (I am Hispanic) and our house income is around $50k/yr supporting 5 (sometimes 6) people. So far my high school career hasn't gone as planned, but I have been able to salvage it. I'm currently a Junior and even though my overall UW GPA is around 3.2 (Weighted 3.5), my last 3 semesters (including this one), my UW GPA has been around 3.7 (weighted 4.1) and climbing. I'm in 3 Honors/AP classes, and on my PSAT score (not SAT) I was projected to get between a 1800-2100 score if I take the real SAT. Last year I took my AP test for European History and got a 4 out 5 on it, so it could count for history credits in college. My EC are playing 2 years of HS Football, joining the Debate Club, Sports talk club, Marine Biology Club, 50 Hours Community Service, Astronomy Club, and I might join the Track&Field Team this Spring. Anyway, if not USC, I'm thinking about joining UCSD or University of Maryland, but USC has been my priority for years. I know it's been hard to get into USC, and I'm really hoping that they could look more closely at my Sophomore and Junior year, and if they do, do you think I could get into to Southern Cal or any of my other options? Thanks.
