SEOUL, South Korea (AP) – The Iowa-based operators of the ACT college entrance exams in South Korea and Hong Kong say they had to cancel today (Saturday), after finding out the tests had been breached.  ACT spokesman Edward Colby said Saturday the cancellation affected about 5,500 test takers who will receive refunds of test fees. Colby says that the exams will be administrated in South Korea and Hong Kong again in September.

South Korea has struggled to clamp down on cheating on standardized English and college admission tests and similar problems have been reported in China.
