Wait... I went to SMDEP at UNMC last summer as well (2013). I'm sure we know each other. My identifying feature would be the blonde guy who sang in the trio of guys in the talent show. Taller, from Nebraska. Do I sound familiar? Clearly I don't want to throw out names, but I think it's awesome you want to go to UNMC!
As for what your odds are. From what they told us at the program last summer: EVERY PARTICIPATING STUDENT IN SMDEP AT UNMC WILL GET AN INTERVIEW IF YOU APPLY. So, there's an in already. The GPA may not be the greatest, but depending on your situation and what not, they will look at that in a different light (possibly). Having said that, I have no idea of what the statistics are of out-of-staters getting in. It is very in-state heavy, as UNMC is viewed as a sort of recycling university (to me anyway). They take Nebraska kids in, and they get spit out right back in to Nebraska to (hopefully) better medical care around the state.
I love UNMC, and I will be applying early decision there next fall! If you'd like, you can message me on here or Facebook! I know a lot of us from the program are friends on there, so just message me if you have the desire.
Good luck with everything!
