Chance me @ Thornton School of Music

<p>Hi,
so I am applying to schools now
I am applying to USC, Juilliard, Pepperdine, UCM, UCR, Carnegie Mellon, Peabody institute, University of Washington, U of Massachusetts-Amherst
as a music major BA degree
my top choice is USC Thornton School of Music as a classical voice major; Soprano.
My problem is that my GPA is really low
its about 2.9-3.0 UW
and my SAT is about 1980
570 CR 770 Math 640 Writing
I got 1st and 2nd places in many competitions,
and did my internship at Colburn School of performing Arts
I also got a young artist award and performed with Southern Philharmonic Orchestra.
I have performed in Wat Disney Concert Hall as an Honor's choir,
I have been a section leader now 4 years,
I have been a soloist for 4 years also.
how much does grade matter for above schools ESPECIALLY USC
also I am currently studying with a professor at Pepperdine. Will it higher the chance of me getting into Pepperdine?
Thank you so much for your time!</p>
