I know someone in UMKC's 6-yr program, and she actually encouraged me to apply. She has time to travel and has been to fiji, new zealand, england, philadelphia, and probably others too since she started the program. I kinda think it would be cool to be 2 years younger with an MD.
Now hypothetically: say you didn't enroll in a 6-yr BA/MD, and went to a 4-yr college like everyone else instead. While you're building up EC's and good grades you're gonna be super busy anyways, so the only free-time advantage that college holds over the 6-yr program is the summers, which you'll spend researching or shadowing or working for maybe 2 of the 4 years of college anyway. Maybe look at the money you'll save at a 6-yr --- it might be cheaper, unless you go to a community college. And the 2 years you save not going to school are two years you could spend working to pay off that debt. I say go for it dude, and i wish you luck (since it's so competitive). 👍
