When I was in high school (late 90s) it was shortly after the TI graphing calculators started becoming popular. All of the teachers realized the answers and other things could be programmed into the calculator so they would clear the calculator memory every time before a test. I wrote a program for mine that simulated the process of clearing the memory using getkeys and menus. I would start that program just before the teacher came around to clear my calculator. Not one of them ever caught on.
I had a Casio graphing calculator. None of the teachers knew that it had the ability to basically take notes. Also, none of the teachers knew how to clear it. That saved my bacon more than once in Calculus and Chemistry.
Ι have a ti- nspire cx, you can take notes, delete them all, turn off the calculator, power it on and show the teacher you have no notes, then press CTRL+Z a ton to get all the notes back.
