China using drones to weed out cheaters on college exam

Admit it, we've all cheated on an exam or a quiz at least once in our lives. Maybe you wrote notes on your hand or "dropped your pencil" to catch a glimpse of your neighbors test. Most of us got away with it, but good luck if you're a student in China.

According to Business Insider the Chinese province of Henan is using drones to weed out cheaters during The National College Entrance Exam.

The test is considered the toughest in the world. Back in 2012 The New York Times wrote an extensive piece on the exam. Some students cram for the test while "hooked up to oxygen canisters and intravenous drips of amino acids during late-night and weekend study marathons."

There have also been reports of schools installing anti-suicide barriers on the balconies at exam halls in the wake of two student deaths.

Still some students cheat, many with the help of their parents. There are reports of students using things like pens and mini scanners that send test questions to a remote location and ear pieces to relay correct answers back from a team of experts.

Students are already screened for devices before entering the exam - women can't even wear bras with metal clasps - and now China is employing sophisticated drone technology to combat equally sophisticated cheating methods.

According to Wired, "the drone hovers 500 metres above the test site and has a range of around 1km. When it identifies a radio signal, it transmits the location of the signal to tablets used by staff."

The stakes are high if you're caught - cheaters are banned from taking the test for three years and could be prosecuted under Chinese law.
