Teachers of reddit, was was the most unique way you caught a student cheating?(r/AskReddit)

Back in high school, our sole math teacher was horrid and there only on a combination of tenure and because Jesus says it’s mean to fire people. (Catholic school)

Going to her for extra help was of no benefit to anyone. I BARELY understood the math and 50% of the senior class was flunking algebra or precalc.

I wrote an entire (admittedly simple) software suite for the calculators we all had to carry, which would show tons of common formulas as well as do them out for you, explaining each step so you could “show your work,” as was always required.

I had a link cable for the calc and doled the software out to jocks and dorks alike. Grades shot up, but the teacher started getting suspicious, and required everyone to wipe their calc’s memory and show her the big “MEMORY CLEARED” screen before exams. So I wrote a program to fake that screen.

A few people (myself included) had their GPAs saved… and now I build online training software and “job aids”/cheat sheets as a career.

Work smarter, not harder, kids!

EDIT: Yes, I know that if you archive programs they survive getting cleared from memory. Adding the phony screen was fun and it gave the userbase a big convenient option instead of this archiving/unarchiving dance. And no, I can’t prove this story really happened, I wasn’t going “gee, better prove to the internet I did this and archive everything” 8 years ago.
