Bests & Worsts Reviews from Amazon

I bought this three years ago when my daughter's high school teacher said she needed a calculator. Money was (and remains) tight, and the reviews seemed to indicate that this would work. For the first two years, my daughter's needs weren't that significant, and frankly, almost any scientific calculator would have done the trick. But her final year of high school featured Honors Statistics, a course that the teacher told us, in no uncertain terms, was college-level in its difficulty. Our daughter was one of two folks in the class without a TI calculator. We thought this would be a problem, as the complex functions she was required to do could be even more difficult if she had to spend time figuring out how to do each one (and not being able to ask the teacher for help). She finished the year with an A in each of her four terms. She got an A+ on her mid-term and her final exams. By the second semester, her teacher had bought one of these suckers and was using it and recommending it to the department head. According to both of them, doing almost all of the functions is much simpler on the Casio. Folks, I suck at math. I can't tell you the differences between the graphs on the two devices or anything like that. But I can tell you that this got my daughter through a tough-as-nails course, and did it with about a tenth of the frustration the TI folks in the class felt (and at about half the cost). There may be something the more expensive device can do that this one can't, but it never came up during my daughter's time in high school.
