Would you go to a Caribbean Medical School if accepted?

Yes.

My goal has always been to be a primary care physician. It's medicine, but it's not brain surgery, it's not nuclear med, it's not biomedical research. It's good old fashioned medicine: casting broken bones, immunizing babies, helping patients control their diabetes, etc.

Frankly, you don't need to go to Hopkins to learn that. I don't need to do a residency at Cedars-Sinai to learn that.

What do you think of this: if I score in the 95th percentile on all steps of the USMLE with a degree from Ross University, how bad am I really compared to a Stanfurd graduate who scores in the 90th percentile on the same exams?

As long as I'm still eligible to take all the tests needed to practice in the US, sure.
