A school in India apologised after making about 50 students wear cardboard boxes on their heads to avoid cheating during exams.
The Bhagat Pre-University College in Haveri, in the state of Karnataka, used this as a trial to prevent cheating during exams last Wednesday.
A staff member took photos of students sitting in the classroom with their heads covered in cardboard boxes which were shared on Facebook and immediately went viral on social media.
Front of the boxes had been cut out for students to see the exams sheet on their desks but restricted their vision to look at their neighbour's answer sheet.
Reacting to the incident, state Education Minister S Suresh Kumar said that such an attempt was not acceptable.
"Whatever be the purpose, they (students) cannot be made to wear cartons for writing exams. There is no rule or advice from us," said an official from state Education ministry.
The school has provided authorities with a written explanation of the trial and an apology, according to school management head M B Sateesh.
The trial was optional and the school had notified parents in advance and only students with parental approval had been involved. Of the 72 students taking exams that day, only 56 took part in the box experiment, he said.
The students had brought their own cardboard boxes to school, and many took them off after 15 to 30 minutes.
"They said they were comfortable with the trial," Sateesh said. "The college did not harass any student, it was optional and some (students) experimented, some did not."
