What are my chances to UVA?

I too feel as if UVa is my top choice.
I am from Hanover Virginia (just north of Richmond) which is known like NOVA for having a high number of applicants.
My sat (is rather low) at a 1270, and my ACT score is a 29(I submitted both)
I am in the top 10% of my class, ranking 20/350, with a 3.7 UW and a 4.43 weighted through my junior year.
As for my classes, I am pretty much all IB, with an exception to math and science, which are both AP courses. Additionally, I have taken two AP level sciences in both my junior and senior years
I have a one generation alumni history to UVa.
I also am extremely strong extracurricular wise, as a member of several clubs, sports, and having a year-round job.
Additionally, I took an atypical approach to writing my essays, and feel as if they are a strong point in my application, and have applied early action (not that this helps anything).

My main point of skepticism is my standardized test scores, simply because I am not the strongest test taker. I know none of you are admissions representatives for UVa, but I was wondering if anyone with past experiences could give me insight on what to possibly expect?
