It honestly depends on the pool of students applying.
One thing I can say about UTA is, is that they really look at considerations. What I mean by considerations is, you took all your sciences @ UTA, you took more than 30+ hours @ UTA, previous degree, and/or Honors college. They are EXTREMELY competitive when it comes to this. If you really want to go to UTA...try taking some of your classes there and get partnered up with one of their hospitals so you could @ least do the AP-BSN Program. As far as TCU, I don't know too much but a few people I know say it's easy...just SUPER expensive...talking 17,000 a semester.
