On another calc forum I visit sometimes (altough I'm not really active) you can get banned for asking help on cheating in math tests with your calculator
At school we were allowed to have all our formulas on a sheet of paper we wrote them on for the entire test, and we could even have math programs in our calcs during the test. Of course it was impossible to use in developpement questions where you had to write down all the calculations to show how you found the awnser but it was useful for awnser choice based questions or question where you only had to write the awnser
In physics tests we werent even allowed to use graphing calcs though, it was only in math tests we could use them
