If a kid is smart enough to figure this out and make it work for them, they’re gonna be fine…
Back when we were doing quadratic equations; I wrote a program on my TI-84 that would ask which parts of the equation you already had, and would fill in the rest for you.
My teacher liked it so much he bought a transfer cable for those calculators so he could get a copy for himself. Then used to to grade tests.
you can code directly on the device, it’s just a PAIN to do compared to moving the files over
I did the same thing. It was allowed in general, with the correct thought, “if you can code it yourself, you know the content”
I had another “program” that would fail to run but that’s because I wrote notes into it. Doubt that was allowed.
Here in NZ they do a factory reset on your calculator at the start of every exam.
I could never remember the formula to calculate compound interest.
But I had no trouble writing a for loop.
