A&M is a great school for computer science! I have many friends who chose to go there for CS even though they got into UT CS. With your stats, you will definitely get in.
Yo I just got accepted to UT on Friday and I wasn’t in top 10% and I’m a texas resident. So clearly it is possible. Not easy, but doable. Might wanna raise your SAT score a little bit (mine was a 1500 if you wanted to know), but otherwise even though rank matters, it clearly wasn’t the breaking factor for me at least.
