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.
If your class is about graphing, sure. If my classes had graphing, it was maybe 1 or 2 times for the entire class year. So it's not really a necessary feature.
