It should be Plan A: MD or DO
DO and MD are equal degrees and have stigma of difference,however, that is within of the medical community. If your goal is to be a doctor, and think that your mom is going to think lower of you, then you are mistaken. In fact, the difference has became ever slim with the ACGME taking over things. I think that DO et Md are both perfectly acceptable options. In rebuttal to the lower match for Do's, I would like to point out that most DO schools accept lower tier applicants. Possibly, those applicants continue to exhibit the same pattern.
If you go to MD, then congratz you went to medical school!
If you go to DO, then congratz you went to medical school!
I believe, in the future DO et MD will eventually become DMD et DDS. Actually, outside of the medical community, I highly doubt anyone knows the difference between DO or MD.
