I went to UT Dallas, and I got a full-ride scholarship without even having to apply for it. I had no extracurriculars to speak of, and my grades were good but not the best (I was in the top 10% of my class, but nowhere near the top of that).

IIRC, it was the third-highest scholarship tier they offered at the time (started Fall 2003). Tuition + mandatory fees + a few hundred a month (forgot the exact number) credit for Waterview rent. No stipend, though, that's only in the two highest tiers.
