Chance me for USF?

<p>Hi guys,
I am a current Junior in Florida with a 3.89uw and a 4.38w (USF scale). I am dual enrolling this semester at a community college, and plan to graduate this year (one year early.) I have a 29 composite ACT (33 reading, 32 English, 24 Math, and 28 Science). I want to major in BioChem. My EC's are a little lacking though. I don't do sports (due to a bum knee from a little league accident 10+ years ago) I'm not a part of any clubs (our school doesn't have any), and have not done much volunteering. My 120 volunteer hours consist of being a Chemistry TA at my HS, video taping a few JDRF events in my area, and organizing a 5k (now an annual event) for a place in Orlando, FL. called "The Russell Home for Atypical Children." They were at risk of loosing their home unless they could repair it, but they didn't have the money for repairs. I and a few other students organized the first annual 5k last year and raised $17k. We are already planning the second annual for this October.
I would like to know if I have a decent chance of making it into USF. Also, will graduating early hurt or help me? And are my EC's too weak or are they acceptable? One last thing - I don't know why it never occurred to me before now, but I just learned that there's such thing as college interviews (I feel like an idiot.) Do you know if USF requires an interview? </p>

<p>Thank you guys so much! :)</p>

<p>Oh, also, all of my HS classes have been Honors, and by early graduation, I will have taken 5 DE classes (18 credit hours)</p>
