Follow this year’s BS/MD thread since many posts related to UH program lately.
For 2016-17 cycle UH mentioned MCAT 32, GPA 3.8, sGPA 3.7. This year still not provided and new PD came on board. So find out what is the final requirement. UH is a guaranteed (conditionally) BS/MD program and your other 2 options you need to go thru regular MD process in 3 years time.
Irrespective of any option, prepare to study well since GPA and MCAT scores need to be competitive.
Assume you meant full tuition and $4k in UTD (full ride normally includes tuition and R&B). Also as a NMF, you are getting free tuition there also. Only additional R&B will cost you which any how you want to be away from home to get a college experience.
UH looks a better choice if you are certain about medicine as a profession, though I have no knowledge about SMU and UTD pre-med advising and their strength. Yes, you have to work hard in UH. Both UTH and UTMB are good choices for MD. For different reasons, UTMB may not be listed in US news ranking.
