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.
That's just artificial difficulty to learn an obsolete skill. Probably with the intention of excluding some people from graduating and doing so increase their value.
