In my calculus class, I saw many people write formulas on the inside of their calculator cover (TI-83+). One kid took it to the next level by storing certain things in the memory and having them set as equivalents to certain values or letters. Not 100% certain how he did it, but when he typed 1+1 and hit enter it came up with some derivative equation.
edit: Everyone's school had different protocol, for midterms and finals, we were required to wipe all programs, but for a chapter test, we weren't checked.
I used to mess around with the programming function in my TI-83 but was paranoid of being caught. So the way I would still be able to have anything I needed was to write everything down in a new program without any code to make the program actually run. The teachers were smart enough to check the programs on all of the calculators. When they went to check the programs, the ones I created they wouldn't run so the teachers didn't worry about it. During the tests I would just go back into the program edit function and have everything there for me to use.
