Summary: But with cation it may be allowed with national exams but my college doesn't allow it at all. I had to return it and purches the ti-84. It seams think a good calculator but does require a huge learning curve.
Summary: I've owned and been happy with several Casio calculators before, but this is one to avoid. The menu system is complex and confusing. The printed instruction manual cannot be read unless you have a magnifier handy. Overall, look elsewhere for a graphing calculator.
