You did not mention that you are in Texas. A quick and dirty way to estimate your chances of acceptance to UT Austin is here: https://www.cs.utexas.edu/~wang/resources/admchances
Plug in your estimated class rank and your SAT/ACT scores, and see.
BTW, since you are talking about “heading into your Junior year”, I assume that you are a sophomore. Your GPA may change substantially by the time you finish your junior year, so there is no real use in figuring out your chances based on your freshman GPA.
Do well on the rest of your sophomore year and on your junior year, and then we’ll revisit this.
