Pre-Med Experience at UT Austin

Hi All, I am a prospective transfer student to UT Austin and was curious as far as what the Pre-Med experience is like in Austin. I have heard that finding research opportunities are hard to come by, clinical opportunities are just as bad. Any one have an opinion? Also, something I am weighing when making the decision to transfer would be class sizes. Are you overwhelmed in your science classes? I’ve heard that some classes have students sitting in the aisles.
