In some things like engineering where there are an absurd amount of notes for the test the teachers will allow a certain size cheat sheet so kids don't have to necessarily memorize every bit of information, just most of it unless you do this.
Oh yea thats fair enough..we have a book for maths ans science with all the formulas in it and we are allowed to use it so its kinda the same! We are just not allowed to write anything in it
...why are you even allowed with a cheat page?
