I shadowed both a DO and a MD, each with different specialties. The DO was an ER attending, and the MD was a Psychiatrist attending. However, I think the MD may be able to write me a more personal letter because I had much more one on one time with him than I did with the DO. I was having some problems getting science letters so I asked a teacher who doesn't really know me due to the large class size, but was willing to write me a letter (whether he follows through with it is another story). I only have two more open slots on my application for letters of evaluation, and don't know if I should include the MD letter or the Science teacher letter. If I include the MD letter, will DO schools think DO is my second choice even though it's not?
