You will likely get in to Trinity but I predict you’ll get much better merit aid from Austin College and Southwestern University. I love SLACs for pre-med students because of the incredible advising.
I know someone going to UT Tyler next year for pre-med. Am I remembering correctly that they are opening a medical school? Also with it being so small you might get more research opportunities and individualized advising.
Edited to say: it does look like UT Tyler has a new med school opening fall of this year.
