I'm a few years out of high school, but during my time anything other than physical calculators were explicitly banned due to the potential for kids to be accessing the internet during exams. I even had a friend who won one of TI's higher end calculators at a math competition, only for him to be banned to use it during exams because of its higher capabilities. Perhaps things have changed in the post-Covid world.
Yeah about the same here. I wrote some programs to handle quadratic formulas. Impressed the Algebra teacher who then let me take AP Computer Science so I can learn to program in Java...which I promptly forgot after graduating HS.
When I was in HS, at the exams we were expected to use our TI-84+ calculators, but we were not allowed to have any programs of our own, so they made us clear the programs before they handed out the problems.
Which you could work around by archiving and then unarchiving the programs. I remember having to do a soft factory reset for one class before exams, rather than just clearing programs. At least they took the policy to its logical extension
