What are the chances that I will get into UT-Austin?

Hello! I just wanted to get some insight into what my chances look like for getting into UT-Austin, as I am starting to narrow down my college list.
I am a female, hispanic, and will be the first person in my family to go to college in the United Sates. I go to a very competitive high school, nevertheless my GPA is still average and I am counting on my SAT scores and AP classes to make up for it. Here are my scores and extra curricular activities:

GPA: 4.45/5.0
SAT: 1480/1600
AP Classes: 8
Class Rank: 296/691

Extracurriculars:
Club and School Sports
VP of National Hispanic Honors Society
National Honors Society
National Hispanic Recognition Program Qualifier
Robotics (Marketing Team)
I also work with a non profit organization, and make videos for their website.
And I am thinking about applying to the UT Research Program this summer.

I have been looking into applying to the College of Natural Science. I have tried to do some research, but I am getting very mixed answers, which is fair considering that the admissions process is different for everyone. Is there any chance that I might get in? Or should I consider this a reach school. Input is greatly appreciated thank you so much!!

http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=788 shows that rank is very important and GPA is not considered by UT Austin. Therefore, your rank of top 43% makes UT Austin an extreme reach. Basically, the automatic admission applicants (top 7% Texas residents) take up about 3/4 of the spots, so everyone else (all non-Texas residents and Texas residents outside the top 7%) is left with the remaining 1/4 of the spots.

Your stats/ECs are quite good. But unless you’re a Texas resident, you should consider UT-Austin a reach. Still worth applying to though!

You won’t get automatic admission under the state’s Top 10% Rule (or 7% for UTA), but apparently test scores are a major factor for everyone else.

“…UT-Austin, like many other universities, is always seeking out more students with high SAT and ACT scores. But most of its freshman class is admitted based solely on grades because of the Top 10 Percent Rule. So when the school considers students who are not automatically eligible, it is especially interested in high test scores — and white and Asian students are more likely to fit that profile.”

But with your scores, presumably you do fit that profile. I’d still say it’s a reach but not unrealistic.
