Just remember
(a) There is a real tuition distinction between Texas residents and non-residents
(b) This school has never graduated a class or participated in a match. Obviously every new school goes through this ie. Western, Arizona most recently.
(c) Their geographic location is "unique". You will be flying through Dallas for the next 4 years. I've driven from Dallas to the border myself. I've done Des Moines to Texas a lot. Dallas to McAllen is just over 500 miles. Texas is a big ass state. No one's done a 4th year at UT RGV yet, but hopefully they don't make you keep coming back because otherwise its going to be a lot of driving.
You should explore if its possible to establish residency in the state because the finances are compelling if its possible to become a Texan.
