This compares with 34% of American, 25% of Chinese and 21% of Indian students.
The results come from tracking students registered at 14 top American universities — Harvard, Yale, Cornell, Columbia, Stanford, UC Berkeley, UC Davis, Amherst College, Duke, Georgetown, Brown, Dartmouth, Pennsylvania and Princeton — between 1985 and 2007.
Korean students appear to consume 75% of the time available for studying, while they allocate only 25% percent to extracurricular activities such as community service.
In contrast, American students and those from other countries tend to equally share their time for both study and other activities.
