Premed in UT Austin vs. in UT Dallas

I’m a high school senior interested in the premed program with a biochemistry major, and I was hoping to get some insight as to what the programs are like in UT Austin and in UT Dallas to help with my decision on which school to go to. Like how much help did the school provide you in applying for med school and preparing you for the MCAT, how difficult it was to get a good rec letter, how difficult was it to get research opportunities and internships, and how are the class sizes (especially for UT Austin ie how much smaller the classes get in upper level courses)? Also, I hear that UT Dallas is a commuter school, so how does that affect the campus life there?

This might get more replies on the UT forum.
