I personally find the buttons on this calculator very difficult to push - I feel the casio fx-300es plus 2 is a much better calculator.

This company controls calculator market in schools. Too many boomers run the DOE in the US.
The Ed Department has nothing to do with your calculator. This calculator isn't as easy to cheat through during a test.
