My chances for Music Business Graduate Programs (NYU, USC, Berkless, Leeds, Westminster etc..)??

Hi, I’m a senior studying psychology / violin performance major at Case Western Reserve.
I will be preparing applications for music business graduate programs in the Fall, and these are my list:

U.S.
NYU Steinhardt - Music Business M.A.
USC Thornton - Music Industry M.S.
Carnegie - MEIM
Berklee Valencia - Global Entertainment and Music Business
Miami Frost - Master of Music in Music Business and Entertainment Industries

U.K.
University of Leeds
University of Sheffield
University of Westminster

I have a semester to graduate, and my GPA is 3.0 (not so great, I know), I interned at concert production / online music magazine startup for 7 months, and at a classical music festival for two consecutive summers. Also, as a Korean student, I served at a Reconnaissance Unit for nearly two years. In terms of music, I was a concertmaster at the university orchestra for a year, and won the university’s concerto competition.

Most of the schools I’m applying don’t require GRE scores; however, since my GPA is rather on a mediocre side, I am wondering whether I should prepare for GRE (I barely have four months to prepare for the test, if I do)

What would you guys say? and what are my chances?

Did you get accepted in USC?
