Interesting; Many of my calculus classes -- university especially, but also high school -- didn't (don't) allow using a calculator at all on the tests. My university specifically mandates one model of calculator for all students. This model can't do symbolic manipulation/graphing and is not programmable at all. My high school had any sort of graphing calculator banned on tests.

I'm surprised that high schools are allowing students to use this sort of calculator (or for that matter, setting tests where it makes a difference what calculator you have.)
