After leaving the exam hall, the pupil remembered there was one particular question that wasn't related to what they had all been taught in class, which had two parts. Many of the pupils use a website called Chegg, which provides answers to exam and homework questions. From the 99 exams handed in, 14 of them fell for the trick and gave the exact answer their own teacher had posted online. All were given an overall score of zero and reported to the university for violating the academic honor pledge they had signed. Their names were also circulated to all the other teachers in the department as known cheaters - and all the other students who hadn't cheated were given full marks for the bogus question.
