I am assuming that you are about to be a senior in high school and will be sending in your applications starting relatively soon. Perhaps three things come to mind in reading your question plus your other thread.
First of all I think that either all of us or nearly all of us cannot really be sure. Admissions will do what they want to do, whatever that is. Admissions is not entirely predictable. I am only giving you my best guess.
Secondly, assuming that you will have good letters of reference to back up your application, to me it looks like what they are likely to be looking for at pretty much any engineering or math honors program is pretty much you. Your grades are great. Your course rigor is great. You appear to have an honest and legitimate interest in engineering. I think that you are doing very well.
Thirdly, from everything I have heard UT Austin is an excellent university. You are fortunate to be in-state at such as good university. I think that it is a great choice, is likely to be affordable for you, and you can do very well with a degree from UT Austin.
My primary recommendation is that you be authentic. Be yourself. Just be honest and straightforward in your application, and in any essays. Meanwhile treat other people well, or at least fairly, and keep doing what is right for you and keep doing it well.
To me it also looks likely that you might end up with a tough decision sometime in the spring of 2026. As one example, what happens if you are accepted to a highly ranked university (let’s say MIT) at full price, and also accepted to UT Austin, to the honors program, at in-state prices? That is a huge difference in cost, and UT Austin is a very good university.
I do not think that there are any secrets that MIT or Stanford are going to teach an engineering student that you could not also learn, and learn very well, at UT Austin. Also if you are full pay at the big name schools then a bachelor’s degree from UT Austin plus a master’s degree from Stanford might very well end up costing your family less compared to just a bachelor’s degree from either MIT or Stanford.
Best wishes and to me it looks like you are doing very well.
