What are my chances on getting into NYU Tisch or some other good drama school like

[llamaboy]

UCI or USC? Im currently a junior and I've been acting since the age of 5. I have plenty of experience as an actor but honestly I'm lost...I've been in several community college plays and only four high school productions, and I have no film experience. My GPA is quite ghastly, as I messed up my sophomore year and I now hold a 2.4. I took my SAT a bit earlier and scored just under a 2000 on my first try. Im confident in my standardized testing abilities as im placed in the top 10 percentile at a competitive private school. (I don't mean to brag, I'm really not that smart I don't know how I do it lol) But I have an obvious reason to be worried for my GPA. Is there any way I can get in on raw talent if I can maybe pull my grades out of the gutter to a 3.0? Acting is my life and quite possibly the only thing I'm good at. It really is my heart and soul and I don't know what I'd do if I couldn't go to a good school just because of a number. If anyone out there has some helpful advice it would be much appreciated.
