well actually I showed it to my math teacher emulating a ti-83 explained the situation and he was perfectly fine with it. He was actually impressed. So all the math test he allows calculators on, I use it.....although I installed spacetime calculator and I use it instead because it is a whole lot more advanced and looks better. And even my chemistry teacher lets me use it on tests! The funny thing is if I wanted I could cheat just by putting stuff in there......but her tests vary too much and I have no idea which ones she will allow calculators on to begin with til we get the test. Sometimes if it is like the six weeks test she will issue the class calculators.

Haha. Another point I just thought of. Yeah it'd be easy to cheat using information typed in the PPC, but it's also just as easy to type information into a program or in "Y=" (the logic works until you get an insane teacher like mine in high school who required everyone to reset their calculator before the test... and checked them all....)
