Chances at UT Austin?

I am a junior in high school looking to major in economics (Liberal Arts), with pre-med. I have a 3.58 unweighted GPA; I got a 1900 on the old SAT and a 1360 on the new one. I’m ranked 82 out of my class of 600, which is the 14th percentile.

I am the founder and president of Investment club, the president of Political Debate Club, Co-Founder and Co-President of Ultimate Frisbee Club, secretary of Key Club, member of DECA, member of HOSA. I am also an inductee of the Chickfila Leader Academy, National Honor Society, and Spanish National Honor Society. I was a captain of the JV soccer team at my school this year that won a district championship and will be on Varsity next year.

I consider myself to be a strong writer so I hope my college essays will be compelling. I’d estimate like a 8 out of 10.

So my questions are:

  1. What are my chances of getting into UT or at least the CAP program?
  2. How necessary is the ACT? Because I’d prefer to study for the SAT again than studying for the ACT.
