Plymouth University in England wanted to discourage CHEATING before their final exams this year . . . so they created posters to hang in classrooms as part of an anti-cheating campaign.



The posters featured a photo of a hand holding an iPhone, and a hand with a bunch of math formulas written on it.  Both were inside red circles with a red slash through them, and the headline said, "NO CHEATING."



Unfortunately for the school . . . the math formulas written on the hand in the poster were REAL.



And at least one student ended up using the formula on the POSTER to cheat on a math test . . . he wrote online that the formula helped him.



So now they're taking the posters down. 






(Here's a picture of the poster.)
