If all goes well, you may have the same quality of education, but your post graduate opportunities, particularly in the aoa surgical sub-specialities, will likely be less at CUSOM compared to KCUMB. KCUMB has historically done well placing people into the surgical sub-specialities.
KCUMB will, without a doubt, provide you with more post graduate opportunities. How much more? I cannot honestly tell you. Is it enough to significantly impact your future? I cannot tell you that either. I sincerely believe you will have more opportunities coming from KCUMB than CUSOM, though.
If your friends in NC are 30mins or more away from CUSOM, youll probably never see them. You will be too busy. Youll also make new friends at which ever school you attend.
If you know you want to do family medicine, like 100% certain, go whereever you want. If not, I would strongly encourage you to attend KCUMB.
Also, I should point out that the person I know who was successful at touro-ny, was exceptional. They had a 36 or 38 on the mcat, but a horrible gpa. They were not average.
