I have also heard that students at UAG get MUCH more responsibility. One can question whether this is a good thing for patients; however, I suspect the standard of care and the legal environment are different in Mexico.

I don't know the answer to the question I posed. Most people will tell you that the clinical learning you do in medical school is minor relative to what you learn as a resident. Thus, at the end of the day, it may not make much difference where you get your med school clinical experience. Still, I think it an important question and I would seek advice from some people who have attended UAG and then gone on to a US residency. They would be able to help you evaluate the tradeoffs.

Also, I would not frame your decision as UAG vs SGU. Rather, I would broaden the decision to UAG vs CA approved carib school (SGU, Saba, AUC, Ross). First, you need to decide UAG vs carib. Then, if you decide carib, pick one. SGU is not the only alternative.
