The National Higher Education Entrance Exam, known as “gaokao,” is held each year and determines whether youngsters will get into the top universities. It’s been described as the “world’s toughest exam” and can be stressful, even traumatic for students trying to achieve higher grades. Some entrants, ingeniously, try to cheat by capturing their test questions and sending them to someone on the outside, before receiving the answers via an earpiece. Unsurprisingly, China wants to crack down on the practise, so one province is now using a drone to monitor radio activity. When a disturbance is detected, it can alert the invigilators and help determine the culprit’s location.
