    I ordered it from www.amazon.de, dont be scared by german language, shipping is only 4 quid and took three days
    Actually I do have €100 lying on a cashcard from the last time I took a trip to Germany (Thankfully I study German A level :tongue:) - Cheers for that!

    EDIT: Hmmm...And it would take up the €100 in their entirety. Would you say the calculator is definitely worth it for that price? What do you use it for?

    See there is only one difference between this calc and the one you got there for 50quid.

    Both got natural display and natural input, but only the more expensive one outputs answers in the natural format.

    If you write "cos (0.25*pi)" you will get 0.7071067812 answer on the 50 pound one and sqrt2/2 on the more expensive one.

    It is a must if you work on complex number.
    Cheap calcs do not support complex numbers, and more expensive calcs do not output natural answers. And there comes 9860GII.

    -it also does factorizing where you put in values of a, b, c and uses quadratic formula. 0.234589 answer = useless, root answer = good.



    To conclude, if you work on complex numbers (FP2, FP3 - FP1 can be done on 5quid casio) I would say its worth it, with factorizing as a nice bonus. If you only do a normal A-Level get the 50 quid one.

    Ah fair enough :-) -what's the model you have like? Useability? Speed? Programming?
    Which one, my graphical one?

    Yes I believe you are allowed, (I think it is the Ti-89 that is banned) although you don't need a calculator that advanced for A2.
