I'm a psychology student and need the calculator for statistics. I was failing massively with my ancient scientific calculator. This calculator is so much easier to use and i am very pleased with the product.

Overall a good product that will allow anybody to undertake advanced scientific studies.  The calculator is a little complicated to use because many of the functions are available through various screens and cumbersome navigation.  some functions should be available directly through the physical buttons (in particular the hyperbolic sine and cosine functions).
