We had a test where I ended up finishing in about 10 minutes. The second person to finish took 30 minutes +. In hindsight I should have went slower because it was obvious no one could have finished as fast as I had.
After the class was dismissed the teacher obviously asked me to stay after class and asked me if I had downloaded all the formulas I had used.
I explained that I did not download/transfer from someone and that I had programmed the calculator to do it for me.
Teacher called me out (probably not believing it) and asked me to program the volume of a cylinder.
Took about 10 minutes to write it up quick, showed it worked and rather than reprimand me the teacher did something amazing.
She said something along the lines of, "If you understand the formula enough to write a program to do it for you, that shows you understand it at a higher level. Rather than punish you, I will still give you a 100% and you are allowed to use your calculator for the remainder of the class as long as you do not share your program(s) with anyone else."
I never had many friends (loner nerd type) so that was easy and it was the easiest 100% I had ever gotten.
