I bought this calculator (well her big sister, 2D) there are 6 years for my first entry into varsity (it was the only permitted). Today I am in 6th grade, and my trusty calculator Casio FX 92 starts to let go of me (since I changed the batteries actually last year) .. So I replaced it with this one which is just as well. Considering the price compared to the lifespan, we can say that it really is a good buy! It is very simple to use and contains many functions (such as calculation of the correlation coefficient, the equation of the regression line ...) and writing 2D is really great!
