Back in 2010, we showed you this ingenious DIY anti-cheating device made out of manila folders:

Fast forward to today and we're quite surprised to find that the trend of anti-cheating hats is still going on strong.

The Telegraph reported that students at the Bangkok Kasetart University were made to wear "anti-deceit paper helmet" for their mid-term exam. The photo, first posted to the university alumni's Facebook page (and has since been removed), went viral.

University officials were immediately put on the defensive - Nattadon Rungruangkitkrai, the teacher of the class, said that he and the students had discussed ways to prevent cheating. The paper hat was suggested by the anti-cheating paper hats.

"It was an agreement between us. No student was forced to wear a hat. Instead, all were happy to do so and thought it was fun. They felt more relaxed during the test," he told Bangkok Post.

Oddity Central reported that the university's student council confirmed the teacher's statement. One student remarked "It is quite normal that people try to cheat in an exam, so the hat helps avoid distractions while doing the test. I feel very bad, and angry, that this has been seen as bad by outsiders."

Anti-cheating paper hat, however, doesn't seems to be effective enough for the students at Thailand's Civil Aviation Centre (allegedly). To combat cheating, they opted for the deluxe anti-cheating cardboard box helmet:

Recognizing that cheating today may be more than just peeking at a neighboring student's answers, a teacher made students surrender their smartphones during the exam, as this viral photo shows:

But the most high-tech anti-cheating techniques take a page from Las Vegas casinos, which undoubtedly have a lot of experience in preventing cheating.

Gaokao is a make-or-break college entrance exam that millions of Chinese students take each year. Dubbed "the most pressure packed test in the world" by Xinhua, it is only natural that many students feel the pressure to cheat.

That's why the Chinese government employs CCTVs and professional exam watchers, as well as wireless signal detector to prevent cheating by wireless headphones, two-way radios and other electronic devices:
