i used my ti-83 in the late 90s for exactly what there were talking about. our teachers would hard reset our calculators before each test but there was a program you could load that would just simulate the menus and pop up the "yeah we reset it" screen and they would hand it back with all my test notes on the calculator intact. so i know why they are doing it. it just won't stop it
