MD Non-Traditional...what are my chances?

Hi everyone,

I am trying to figure out what my chances will be to get into and MD or MD/PhD program. It has been 6 years since I have graduated from college with a B.Sc in Biochemistry. In those 6 years I have been working as a research technician at a major university (top 20). I have published 3 papers: 1 in Nature, 1 in Science, and a first author paper in a more specialized journal. I have had 2 posters, and will likely have 1 more first author paper before the application cycle begins.

My undergrad GPA isn't the best, 3.3.

My LORs will be from PIs that I have worked for, my current PI holds a high ranking position at my university in addition to being a MD/Phd.

I am scheduled to take the MCAT in May, though I'm a bit worried about how well I will do to make up for my lacking GPA. How quickly study habits die when being out of school for 6 years!

I am a white female from a disadvantaged background (not sure that matters since I'm non-traditional?)

Any advice/suggestions to make my application stronger would be greatly appreciated :)
