pffffttt!!!!!

I think juice just came out of my nose...
To save you some grief, this is a very controversial topic, that most people that are wanting to go to DO school have to fight tooth and nail with the pre-allo people with all the time. For some reason the preallo students think that the DO degree is more like a witch doctor mojo jojo degree than an MD degree. Its not. DO students actually take the exact same classes as an MD student, plus some extras in OMM which are osteopathic medical manipulation (right??).
So to answer the questions:
1. They are practically the same. Classes are the same. In DO school you are taught the principles of Andrew Taylor Still, the founder of osteopathic medicine. You can resort to some google-fu if you want any more info, or just visit
AACOM the Association of American Colleges of Osteopathic Medicine website for more information.
2. Its just as hard to get into DO school as MD school. I think the average MCAT and GPA are a few tenths of a point lower for DO school because they don't weight these criteria as heavily as MD schools do. They look more at the person and their personality versus just book smarts, and are more forgiving of "issues" you might have had in undergraduate studies. But again, they are just as competitive to get into as MD schools.
3. More challenging... Im gonna say tie again. Med school is not easy. DO students can go and be residents in MD programs or DO specialty programs so I guess its as challenging as you make it. Just because you are an MD does not automatically make you a good physician. Just as being a DO does not automatically make you a quack Dr. Ask JPH, who posts on here, I'm sure he is full of opinions on whether or not DO school is challenging.
4. As I said above, DOs can apply to both MD and DO residencies, so they are not confined to family practice or working out in the boonies in an urgent care clinic. You will probably have a better chance of scoring the MD residencies as a DO by taking the USMLEs vs. the COMLEX exams for DO students simply because the COMLEX is relatively new (past 20-30 years I think...) so the MD residencies are still trying to convert scores between the two tests.
I think I answered your questions, and if you have more ask. Maybe put a disclaimer when you ask them that you are not trolling, because it has happened all too often, and its not a good outcome. Feel free to pm me if you do have any more questions, or just ask here, I or someone will help you out, I'm sure.
Those more in the know, please correct me if I am wrong, or if more is needed.
