Hello James.
After contacting our suppliers they have advised for the Casio FX-991CW Scientific Calculator.
The fx-83ES is specifically made for Spain therefore exam mode and language can't be changed.
As for functionality, I am unable to advise as it's down to personal preferences and requirements.
Thank you for using Q&A.
It comes with a clip on case, well more of a cover. It does the same job but its cheap feeling.
Hi Izzy,
This does not include a case.
Thanks for using Q&A.
The EX was a FAR better built calculator, it has identical functions but the CW is predominantly menu driven as opposed to the more user friendly EX. The ONLY extra on the CW is a simulated dice roll function that is pointless. The CW is less user friendly as a result
Dont buy an EX now however because it will probably be fake, Casio changed the layout and function of the CW significantly to set it apart from other, shall we say more economical, brands, in order to make forgery more difficult.
