THE LATEST weapon in the fight against cheating on China’s all-
important college entrance exam is a six-propeller drone.
The contraption flew over two testing centers in Luoyang city in
central China’s Henan province to scan for any unusual signals
being sent to devices smuggled by students taking the annual
test. No such signals were detected Sunday, the first day of the
exam, a Henan province news website said.
The drone cost hundreds of thousands of yuan (tens of
thousands of dollars) and is as big as a gas station pump when
extended, said LanZhigang, from Luoyang’s Radio Supervision
and Regulation Bureau.
“In an urban area full of tall buildings, various barriers limit the
operating range of devices on ground, while the drone can rise
up to 1,640 feet and detect signals over the whole city,” Lan
said.
Almost all Chinese high school graduates must take the test and
the scores are the key criterion for which tier of university they
can enter.
Pressure is immense and many students spend months cramming.
Parents travel to the cities where the tests are given to stay with
their children during the exam, which can last two or three
days.
Cheating is common given the high stakes, and methods include
selling supposed answers, hiring surrogate test-takers and using
wireless equipment to communicate during the test.
