I have a qustion about the casio fx-300es calculater. I am taking a state exam and calculaters that are programable, have alphbets and make sound are not allowed. Does this calculater have any of these...

The Fx-300ES does not have any of the nifty features you are not allowed to have. You cannot program it=non programmable. It does not have a QWERTY keyboard and it is totally mute.
It does have a few variables that can be used to store values (A, B,C,D,E, X,Y but I believe that does not disqualify it.
You may want to check your state's exam website for a list of allowed calculators.
