The TI-36X Pro and TI-30X Pro MathPrint keep their history when turned off and I don't think those are banned by schools. But yeah catering to exams is why lots of features are missing. I wonder how the HP 35s got away with being able to store formulas and being programmable and yet being allowed in many exams.

Yeah, the TIs do retain calculation history. I'm assuming it's less of a concern in the US, which is TI's primary market, while Casio tends to be a bigger deal outside the US, where a lot of their exam restrictions come from. Not sure what the 35S secret was to getting accepted!
