I did the same thing, implementing formulas we learned as interactive programs in TI-BASIC. I don't think I even tried to hide them or use them on tests or anything, but when I told my teacher at the time (2003-ish?) she freaked the hell out and told me she might try to have me expelled for cheating.

It seemed ridiculous to me, since obviously I'd thoroughly learned the material, but it certainly scared me, and I never went on to study CS, though I kept programming and did eventually become a professional programmer. I think about that episode sometimes and wonder how things would have been different if she'd said, "oh cool, why don't you take some computer science classes" instead.
