From the Republic of Texas thread, here are the TX schools averages:
LizzyM scores for matriculated students are:
1) Baylor - 73.4 (3.84, 35)
2) UT Southwestern - 72.4 (3.85, 33.9)
3) UT Houston - 69.3 (3.76, 31.7)
4) UT San Antonio - 69.1 (3.73, 31.8)
5) UTMB - 67.7 (3.87, 29)
6) TTU Lubbock - 67.5 (3.65, 31)
7) Texas A&M - 66.7 (3.66, 30.1)
8) TTU El Paso - 64.8 (3.6, 28.8)
9) TCOM - 64 (3.60, 28)
Your LizzyM is slightly below but I think you'll have some success if you apply very early. I had similar stats as you, and applied to the TMDSAS schools + a few OOS DO schools (including NSU), and (fortunately) had a great deal of success. I applied in May though, when TMDSAS opens.
