A load of crock, just by simply scanning the oral marks I see no difference in the mark distribution between the whites and non-whites. This being the editor's own opinion makes him seem biased, imho.
This is what you said. My simple scan of the top twenty oral results in the first batch shows 16 whites, 2 Hispanics and 2 blacks. Why is that an insignificant variation between white and non-white entrants?
