You reminded me of my physics teacher in high school.

I was very into my graphing calculator (TI-86), down to coding in assembly to make silly little games. My previous teacher made me show that the memory was cleared before any test.

But his take? If I wrote a working application with all the formulas necessary to take the tests, then I put in the work to learn the material, and he didn’t care. I hadn’t done that, because I expected to wipe it, but after that I did and showed it to him (and gave him the code).

Found out he would show off what I made for a few years before retiring, specifically to point out how I did something I found fun to learn.

More teachers/school systems should be like that.
