While I currently don't have the stats to tutor the MCAT, I tutor the subjects that are on the MCAT ... I teach them semester after semester, year after year. Every semester I have to teach people how to derive the Michaelis-Menten equation on an exam, or the organic chemistry logic behind the citric acid cycle and the Calvin cycle. The amount of studying I did for the MCAT was like ... 30 hours. Format only.
No, it's not just my personal experience, but the personal experience of me and almost a dozen members of my communities. I think it's reasonable, drawing on the experiences of my peers (N=12) that statistically, MD physicians are less likely to be compassionate to members of the marginalized communities I belong to w/respect to DO physicians. That is my current assertion. Have you ever interviewed the LGBT community? The LGBT community is way less resentful and suspicious of DOs than MDs and that's a fact. Maybe if MD physicians didn't want to feel so insulted, they should learn to treat these communities better.
