Apparently, 44% Koreans who start in "good colleges" drop out. (Please note that the headline is incorrect: the Korean's alma mater is most certainly NOT in the Ivy League. It belongs to Pac-10, and plays far better football.)
The article does not say how the dropout rate breaks down among Korean students studying abroad since colleges, Korean students studying abroad since between middle school and high school, and Korean Americans - which would have been the most useful data, particularly because this data goes so much against the Korean's own experience.
At any rate, that's a lot of disappointed Korean mothers.
