CASIO fx-991CW for A-Level Further Maths?

I am about to start my A-Levels, one of which is in Further Maths. My school tells us to have a CASIO fx-991EX scientific calculator for this course, however I already have an fx-991CW. Surely this is good enough? What is the difference? Is there any reason I should have an EX instead of a CW?

The CW is just a redesigned version of the EX, you should be fine. I personally found the CW format and interface massively infuriating to use, but I suppose if you don't know any different then it might work for you.
