Korea, whose students dominate international exams, also is the least satisfied with its educational system within Asia. Only 56 percent of Koreans responded that they were satisfied with their educational system. The approval ratings were similarly low for other high-achieving nations like Japan (61%) or Taiwan (74%). Interestingly, over 95 percent of Singaporeans were satisfied with their educational system.

This says something, but the Korean is not sure what -- at least for now.
