You are absolutely correct-- I know a girl with a 4.0 or better and 1230 SAT who isn't in the top 10%, so she wasn't accepted at UT. Unbelievable.
But, Texas A&M accepts any Texas resident with 1300 SAT, regardless of grades. That's a good policy.
It's a well-known fact that it's easier to transfer into A&M or UT as a sophomore from another college than to get in as a freshman. That's because of all the top ten percenters flunking out.
Ridiculous.
Texas Tech also has definite acceptance of anyone with a SAT over a certain amount. It was about 1200 a few years back.
