What are my chances?

I am looking to double major in Theatre Design and Production and Chemistry. I have a 4.13 GPA and a 24 ACT (it is low I know). I take all AP and PreAP classes. I am very involved in theatre and was president of our ITS troupe my junior year. I am in NHS, ITS, and have documented volunteer work. I have already completed part of the audition process for theatre, but I am wanting to know the chances of getting in the actual university.
