Your chances for UVA and UNC as an OOS student are low, because of your GPA.
First, if you apply Early Action to both UVA and UNC, they will be making an admissions determination based on the grades at the end of your junior year (or perhaps the summer if you take the class you reference). Your current GPA won’t be competitive for UVA or UNC; and even if you have a 4.1 weighted GPA by summer’s end, I still don’t think that it’s enough. Second, it’s hard to predict just how well you will do in your classes over the summer and next year; and you might not do as well as you think you will. “There’s many a slip twixt the cup and the lip.”
Insofar as your ECs go, you have lots of memberships but the overall impression is one of resume building.
Low chances for Emory, U Chicago, and Northwestern, also, for the same reasons above. You should not have too much trouble getting into school in Gainesville as an IS student, however.
