In my youth, cheating used to be done by whispers and written notes in cuffs (I’m aware that makes me sound ancient). Nowadays, cheats have embraced new technologies. There is the case of the student that loaded all the notes in their palm pilot. Another one that photographed the questions with their mobile phone, sent them to friends outside via MMS, and got the answers to the questions. In another test, a student dictated the notes into his iPod and listened to them during the exam.
If they spent the same time studying, they wouldn’t need all the technology. They just don’t make students like they used to.
