If Mississippi is where you want to do residency or practice medicine UMC is the choice for you. Other than that, UMC provides a marginal education which seems to be only slighty better (in terms of USMLE scores) than most progrms in the Caribbean. If you can get around state residence in any other school or have the money and MCAT/GPA for a private school, go there.
I truely had this vision of UMC being this grand place of medicine and research but once I got there, walked a mile to the medical school I was completely disappointed. I can truely say it is nothing more than Shoemaker part II. The facilites were rundown and there seems to have been no effort into modernizing. The faculty that I interviewed with were rude and egotistical and most of all Dr. Case was just a complete "ASSHOLE." When we meet back in the early Fall everything was "great" and "wonderfull" but the interview day it was like meeting Dr. Jekyll and Mister Hyde.
What did you wish you had known ahead of time?
How completely uncompetitive UMC is on a national level to other medical schools, and that if you have any desire to enter a competive residency or even leave the state of MS for residency, you have a snow balls chance in Hell of getting it.
