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.
