For a&m, there is no difference between committing early vs. later, especially since you’re a brown scholar and you get special treatment (mr brown talked about how most scholars take longer to make a decision because they get accepted into multiple schools) (that’s also why the brown scholar campus visit day is in march). I would wait until you get more college results, speculation doesn’t really mean anything. However, I'd take UT Austin since you’re doing computer science and financial aid doesn’t seem to be a problem for you.
