Cheating is a major problem in education in any country. However, it is rare for cheating to be screened for on a country-wide basis.
Very recently, China and South Korean SAT test takers are having their test scores delayed due to mass cheating at regional test centers.
The Scholastic Aptitude Test in the US is the equivalent of Asian college entrance examinations, and scores have a large effect on the quality of schools students are accepted to and the amount of student aid they receive.
