Drones will be used to catch cheaters during China's National College Entrance Exam (a.k.a. "Gaokao") — a test that's been called the world's hardest exam.

Authorities in Luoyang, a city in the Chinese province of Henan will put newly developed anti-cheating drones to work during the two-day long exam, which is taken by up to 10 million Chinese students across the country, according to Edu People (Chinese).

In many parts of Asia, there's extreme pressure for students to perform well on entrance exams. Pass and you will be on your way to university. Fail and you'll have to settle for an inferior school, get a job instead of getting a college education or retake the exam in a year.

So much weight is put on the exam that some overly stressed students have turned to suicide as a way out. In 2014, there were 79 cases of student suicide related to taking entrance exams among elementary and high school students in China, according to China Daily.

Cheating is also another rampant response to the high-pressure entrance exam. But unlike the old answers-written-on-the-inside-of-a-water-bottle-label tricks from back in the day, Gakao cheaters have used sophisticated equipment such as glasses with embedded cameras, pens paired with in-ear receivers and all kinds of crazy hacked-together solutions like T-shirts with hidden cellphone and radio transmitters.

To catch these cheaters, the Luoyang Radio Authority has developed special drones that will hover 1,640 feet in the air above testing sites, scanning for radio signals up to 310 miles.

Test administrators and staff control the drones using tablets. When the drones detect a radio signal, it will beam data to the tablets for staffers. Drone operators will then try to home in on the radio signals by flying closer to the detected source.

From there, it's only a matter of time before a cheater is caught. Cheaters caught by the drones will face penalties and possible prosecution. They also won't be able to retake the exam for three years.
