Ok OP, based on your other posts you just want to go to UT Houston. I assume you're asking the TMDSAS question because UTH is the only school you want to go to. And just like you don't want to have to volunteer, you don't want to have to take both the MCAT and GRE, and you don't think you should have to pay for things, it's not surprising that you don't think you have to apply to a Texas school the way everybody has to apply to Texas schools.
