I wasn't aware that calculi (?!) did moduli (!!), mine definitely doesn't, is yours graphical?
You'll have to show your working anyway, modulus functions aren't too challenging are they?

Ah, so you can! (I have the CFX-9850G PLUS). The other way of course is to do sqrt((f(x))^2)), a bit of a botch but also works!

Yes as long as they don't do symbolic calculus. That means 98-- series casios are allowed, but 99-- series are not.

You can't use graphical calculators in P1 or P3, but they're fine for the others (as long as they don't have any other banned functions)

It depends on the module. In my maths pure modules, I could only use a graphic on Pure 1 and 3, on 2, 4, 5 and 6, only scientific calculators were allowed. However, I think you can use them on all other modules though (stats, mechanics and discrete) at least for my exam board (AQA Maths A).
