This "source's" confidence thing doesn't seem to make sense to me. Every school thinks they have found their next class of students when they do the match. That's what the whole point of a wait-list is, because some accepted students ALWAYS drop out. Just b/c the school thinks they have found their 50 students doesn't necessarily mean that those same 50 students have found their school. Could you honestly say that if another offer came yesterday from a more prestigious medical school, (Due to the May 1st deadline), that you wouldn't immediately jump the UTRGV bandwagon and head out to green pastures? Let's face the fact that UTRGV isn't the most ideal or desirable place to live or go to medical school for a lot of people, (I'm not saying that it's bad in any way, it looked like a great campus with a lot of perks, but I'm also sure that more people would be interested in going somewhere else more established or with a bigger city if given the chance)... I'm sure that there will definitely be some significant movement from students, (Unless this medical school was their only acceptance or if they live close by.)
