I have to agree with Goro on this one. You have a guaranteed pathway to becoming a doctor. You might be interested in plastics now, but you will likely change your mind since most students do.
I'm sure everyone else on this forum has already drilled you on GPA, MCAT, and Clinical Experience (of which you're missing the latter two), but no one has yet discussed the mental stress of admissions cycle. When you took the MCAT, you had to wait a few weeks anxiously, right? Imagine that but twice as more intense and lasting almost a year. That is what 60% of students who apply every year experience. I already have an MD admission, but if our school offered me a BS/MD or DO pathway, then I would take it since I wouldn't have to be so anxious during the admissions cycle...
