No B.S. and MCAT
I got into med school without a B.S. but I did take the MCAT and had 90 semester undergraduate units. I',m sure residency programs do not look at either undergrad and MCAT records since they will look heavily at USMLE scores, med school grades, and performances in rotations that reflect the skills you need as a doctor. I work at a local teaching hospital and alot of the foreign educated physicians who are residents now did not have to take the MCAT or have an undergrad degree to get into med school in their country's education system. However, there are some States that require a certain amount of undergraduate units before obtaining a medical license, but that is only a few I belive. It would be Best to call the State medical boards of the States you wish to practice in and verify if they have any restrictions on licensing graduates without a ** or MCAT scores. It may be interesting to also contact some residency programs and ask if they place any scrutiny on an applicants premedical and MCAT record. I'd be very surprised if they did. Good luck.
I don't think that everything is possible, but I do think that anything is possible!
