Teachers at a top Thailand university have gone to extraordinary lengths to ensure none of their students cheat during exams.
A picture has emerged on Facebook showing rows of students sitting examin wearing bizarre headgear complete with paper flaps on either side to prevent them looking at each other's answers.
Kasetsart University is a top-ranking university in Thailand.
The university board said the "blinker hats" were not intended to humiliate students.
The Bangkok Post reports that nearly 100 KU students were pictured wearing the hats during an exam.
The board has since issued an apology.
It said the hats were considered necessary because the room was small.
