text: Students might not follow the rules of turning the phone off during class time. They're most likely to use it to cheat on a test. For example, if you were a student and just spent all of last night working on your homework, got almost no sleep, and you suddenly realize that there's a big test today that you forgot to study for. Would you as a student go with the F? Or would you try to cheat on your cell phone so that you could pass the test? Students don't like getting bad grades because their parents ground them or punish them for it. If students can have a way out of getting this F on their test which would later pull down their final grade, then they would do it.
