Audition Recommendations?

[Tubaccordion]

I am auditioning for University of Miami as a therapy major.
I auditioned last year as a high school graduate with the 1st movement of the Hindemith Sonata and the last 3 movements of the Effie Suite.
Although I received positive feedback on the audition, I was not accepted due to a somewhat low GPA (3.2).
I am re-auditioning as a transfer student and hopefully getting in for Fall 2013.
What I want to know is what pieces would be good for re-auditioning?

If you have changed your GPA, and the audition pieces went fine last time, why change the audition pieces as well?
