What are my chances of getting into USC

I am a junior in high school, female, caucasian, and live in N.Y. My SAT superstore was a 1620 (horrible I know, but I am taking it again in a month). I am going to take the ACT in october. My weighted GPA is a 3.7 and I am taking four International Baccalaureate classes, all of which I get grades in the 90’s, high 80’s. I am also in Honors Marine Biology. I want to apply to the USC Screenwriting program. I have already co-written a full length screenplay in which I am co-directing and am starring in. I am hoping to get this project completed by september. I am also currently writing another screenplay on my own.

I am the president of Film Club at my school (that I started)
I have been a member of youth court for two years
I have acted in two school productions
I have acted in a Stonybrook college two actor skit/play
I am currently waiting to see if I got into National Honors Society(But I think I will)
I have volunteered, three years in a row, at an internationally known Film Festival
I got into, and went to a Screen Acting program at the London Academy of Music and Dramatic Arts
I got into, and this summer will be going to a Musical Theatre, and Contemporary Text program at the Royal Academy of Dramatic Arts

What do you think my chances are of getting into USC? I really, really, really, really want to get in! I visited the campus and went on a tour in december and I fell in love right away. I am going to apply with no financial aid too, if that makes a difference (but I don’t think it does because they are ‘need blind’).

Thank you so much! Any advice and any tips on how to make myself look more interesting to the USC admissions people would be greatly appreciated!

Hey! I was recently accepted to USC for the fall of 2015 and have been very interested in their admissions process for a while now… there film school is incredibly difficult to get into so you’re going to need to have extracurriculars/accomplishments that REALLY showcase your talents in that field… However, it’s going to be impossible for anyone to even attempt to “chance you” without standardized test scores… As a junior, you should have already taken either the SAT or ACT but taking it as a senior suffices as well… Best of luck.
