This calculator is much thicker and heavier than other Casio calculators I have used. For Further Maths, this calculator and its smaller brother the fx-991esCasio FX-991ES Calculator
make ideal companions. This calculator alone is not enough for Further Maths. I bought this calculator for its graphical capability. This was the first calculator that I have bought that I had to read the manual before I used it. The Menu system took a little bit of getting used to, but now I love it. In each different mode the top F buttons are used to bring in the different functions. There are some effective add ons to this calculator namely adding CAS to the menu, which gives many extra features to the calculator.
The calculator is programmable but learning the programming from the manual is difficult as it is rather weak. Many of the add ons available are games rather than programer to extend the functionality of the calculator.
I went for the SD version of this calculator rather than what my students chose. The SD version allows much easier movement of information to and from the computer, much better than the USB lead that is supplied.
The calculator takes a lot of getting used to. It is not simple to use. But it is very powerful and quite intuitive once you have read the manual (and understood it).
