I bought this calculator for my A level examinations. It is terribly handy, I do a lot of maths and be it calculus, vectors, complex numbers or statistics, this calculator will help you a lot. Not only does it boast 403 functions, and most of the keys look like that should be on a UFOs spaceship, if you read the handbook and know how to access and use the functions it is great. These functions are not ones that allow you to cheat ( sadly :P) but they do provide a good basis to check your answers, which can be very valuable when you have no clue whether you good be right or not. Also it comes with a solar panel, providing two way power, meaning you dont have to be scared about whether it would stop in the middle of an exam.
