It's relatively difficult to place the Texas school into tiers, as they are all great and offer a unique variety of things (and they are all super cheap for Texas residents!), but I'll give you some 2014 admissions information about the schools so you can see where each school is from a pure numbers standpoint. Below is a sorted list of the Texas schools with their
LizzyM scores (median GPA x 10 + MCAT Score; ie a 3.8 cGPA and 31 MCAT would be a 69):
1) Baylor - 73.8 (3.88, 35)
2) UT Southwestern - 72.8 (3.88, 34)
3) UT Houston - 71.4 (3.84, 33)
4) UTMB - 70.7 (3.87, 32)
5) TTU Lubbock - 69.8 (3.78, 32)
6) UT San Antonio - 69.4 (3.74, 32)
7) TTU El Paso - 67.6 (3.76, 30)
8) Texas A&M - 67.4 (3.74, 30)
9) TCOM - 64 (3.60, 28)
Again, this list is strictly from a numbers standpoint (GPA and MCAT). There is no real good way to rank the Texas schools, but this is just one objective way to do it. I do not think one school is necessarily better than another because it has higher admissions standards, though I do admit that there is probably a little to be said for that. (Harvard is harder to get into than "x", or Johns Hopkins is harder to get into than "y", probably because they are the "better" schools). People will argue this point extensively, and it's very crucial to not read too much into these numbers. However, they do exist, and I'll argue that there is at least a little bit something to them because they are here for us to see and schools will flat out reject certain applicants because they do not meet a minimum GPA or MCAT requirement.
But again, there is a ton of gray area here. And it's important to not just choose a school over another based on these numbers. Choosing a medical school is a very personal and complicated decision. However, when you are applying, it's good to know these numbers because they can be good indicators on whether you have a good shot or not. Just something to consider. Thanks and good luck!
