Hi.
I am using the Casio fx-570ES Plus calculator and have been for the past two or three years. Its what I'm used it and it's never gone wrong for me.
However, I heard some people say that, in Maths exams (such as C2 where you are allowed a calculator), your calculator must not have the ability to integrate or differentiate - or something like that. Does that disqualify my calculator?
If so, which calculator would you recommend? Anything similar to my present one?
Thanks in advance.
