Authorities in India expelled 600 high school students for cheating in exams. The pupils used a dangerous way to get help – their parents climbed the school walls and gave answers to questions through the windows. Photos and videos of this illegal technique have gone viral. They show dozens of parents hanging on to the walls three stories up to give answers to their kids. Teachers found many cheat sheets that were made into paper airplanes.

Over 1.4 million 10th graders took the tests across Bihar state. Bihar's education minister said schools faced a difficult job to secure exams. He said: "It's virtually impossible to conduct fair examinations." It is difficult to monitor parents who take their children to school. Parents helping children cheat is now so common that police officers work at each school. An official said, "we can't use force to drive away the parents".
