Did you get your app in by December 1st to be eligible for any merit scholarships to reduce their huge tuition bill?. Unweighted 9-11 seems like it might be too low, as well as ACT. They seem to favor applicants with high test scores. They may offer you the transfer guarantee, where they admit you junior year year if you are absolutely over the moon for USC, but it will likely take three years to graduate and involve hefty student loans. Proceed with caution.
