What are my chances of getting into ut austin?

I have always wanted to go to UT because my neighbors and everyone around me went to UT and I kind of grew up in that environment. So at my school we only have 160 students in our grade. I am around top 15 or top 20% in my class. But my gpa weighted is around 4.02 and my SAT score is 1500. What are my chances of getting into UT? (I also have more time to improve my SAT score if that could help)

What major?
What course rigor?

Wanting to go to UT because everyone you know does is not a well thought out reason (in addition, it’s dubious everyone you know went there seeing how selective it is). Improve your rationale. Being able to articulate why you want to attend can matter.
Then look for schools that share some characteristics - perhaps UAlabama, or Tulane, or Emory. Ask for information from them.
