I find it incredible that these calculators are even allowed in exams. In the UK, for University, we were allowed at most a Casio fx series scientific calculator, nothing more sophisticated. At A-Level (pre-college) you were allowed very basic graphical calculators but I knew of nobody that bought one and they were seen as being pointless.
