You’re a very good candidate for UT. Just keep in mind with the application to UT, you need to apply to both the school AND your major, otherwise, you’ll get capped and given a different major. If you applied by the priority deadline that may give you a boost in admission.
From those in my school who applied to UT but weren’t auto admit, their chances dropped drastically. Frankly, many of us say that applying to UT is more of an extreme lottery to get in. I know several students who were not in the top 6% and were rejected from UT but went on to attend universities like JHU & more.
From my view, applications to UT is a game of chance, whether you get in or not is extremely difficult to chance.
Congratulations on your other acceptances, however! A&M does have a strong government program both undergraduate and post-graduate with their Bush School. Best of luck.
