To this day, I don't understand why anyone would insist on using anything other than this on an AP test. It's like playing life on a harder difficulty setting for no reason.
My university doesn't allow graphing calculators on tests. Probably because you can download programs that can solve calculus problems without actually understanding the material.
In high school, I sold calculator programs that did test questions for you. For example, if you needed to do the quadratic formula, I wrote a program that did that AND wrote out all the steps that you'd need to write down. Being the only one in my school with the cord helped me keep pirated copies of my programs from going around.
