They'll need to be nerdy to get into UT or A&M; grades and ACT/SAT need to be better than SMU.
The difference in the Ponies and Frogs is that they actually look at almost all applicants, and they grade highly for leadership and extra-curricular activities. They create a modified GPA, that penalizes easy classes and rewards AP & dual credit. The statement from each was essentially the same; we'll take a 3.5 who's a leader and very involved over a 4.0 who's only a student.
I find that refreshing, and it will probably translate into better likelihood of success.
UT looked at only the top 7% of class standing last year, and still lost over 20% of the freshman class. So, that evaluation system has not proven to produce the best candidates.
