Ed just got back from giving a talk at an elite college here in the East. Astonishingly, at this particular college the faculty does admissions, or at least is actively involved in admissions.
One of the professors told Ed that if you took everything on the applications at face value, half the entering class each year would be from China. The trouble is that with apps from China, no one can tell what's true and what's not.
He didn't know what the ultimate percentage of Chinese admits is.
