I’m sorry to say I find your post confusing. You are living on campus at a boarding school from which you are graduating next month but you haven’t applied to college yet?
In general you would be considered a resident of the state in which your parents live.
In any case, your GPA is lower than what is normally considered admissible at the schools you asked about. It might (but not at all definite) be OK for performing arts if you are super talented and the performing arts program wants you. I know someone who in a recent prior year admitted to UT Austin College of Fine Arts for Dance with a GPA in the range of yous. But, their acting program is incredibly selective…as in they only accept 16-20 people each year so it seems like a very long shot.
Being 16 probably won’t have an affect on your admissibility.
If you’d like recommendations for other ideas please let us know what state your parents live in and your budget. Best of luck.
