This. Though I'm only in the application process myself, my whole motto through the last 3.5yrs was to be an MD. If you want to compete with MDs for their spots, then be an MD (do what MD students do). Rotate at top hospitals in the country, prove your worth, get a letter. I've noticed a lot of DO students are timid and think they aren't as good as MD students so they don't rotate at large academic places. This couldn't be further from the truth. I haven't met one doctor that A) cared what school I was from, or B)didn't teach me because I was an outsider, or C) treated me differently in any way. Show up, dress well, act smart, don't be annoying, work hard, get letter from dept heads, win.
