We couldn’t use graphing calculators on calculus exams. There were professors who banned calculators entirely.

I'm confused at these comments because it makes me think the commenter didn't go to college. All my classes were basically open everything except for a literal laptop. Calculators were not useful.

at my university in math exams we were only allowed to use 1 specific model of calculator, and most of the exams were answered symbolically anyways, so the calculator usually was not helpful anyways.
