Chinese students sat the annual make-or-break university entrance exams on Monday, with officials deploying drones or high-tech radio surveillance trucks at schools across the country to try and curb increasingly sophisticated cheating methods.
Authorities have become increasingly concerned about the risk of students using devices such as smart phones — some of which have become smaller and easier to hide — as an illicit aid during tests. Officials in Luoyang, in Henan province, purchased a drone designed to search for radio signals that could indicate cheating students, according to the Dahe News , the official provincial newspaper.
