Unlike AMCAS, the 165$ fee applies to all ten TMDSAS schools. Whether you apply to one or ten, the application is still 165$.
The schools I know of that do not have a secondary:
Long at UT San Antonio
UTMB in Galveston
The schools I know of that have a secondary but no additional fee:
UNTHSC TCOM in Fort Worth
UTSW in Dallas
Dell at UT Austin
The schools I know of that have a secondary with an associated fee:
UTRGV in Brownsville/Valley area
TTU El Paso...in El Paso
TTU Lubbock...in Lubbock
Additionally:
A&M has a fee but also requires you to take CASPER, requiring an additional fee to the additional fee.
I’m not sure if McGovern has a fee or not. My application cycle was the last cycle they did not have a secondary.
