I've already torn into the OP's post, now time to correct you a little bit.
1. Facts remain that averages for Texas school's are lower than national averages, though this does not make Texas schools bad.
2. UTSW and Baylor are only in the most competitive schools in the country if you consider out-of-state residents; their acceptance rate in-state puts them in mid-tier for competitiveness. This applies to both schools since:
3. Baylor fills 90% of its class from in-state as per the school's agreement with the State of Texas. This agreement is what allows Baylor to have such low tuition for a private school.
Finally, congrats on your acceptance and good luck in school!
