I 'cheated' in my Astronomy 1001 class by reverse engineering some sort of moon phase calculation I was supposed to do every day, by hand, for a month.
I didn't want to check the location of the moon at the same time every day so I just worked out the math instead, and then fudged the numbers on the worksheet so they wouldn't look too perfect.
I did this back in...1999 or 2000, I think? Apparently kids are still doing the same silly assignment a quarter century later: https://www.reddit.com/r/uofmn/comments/1km6zzv/comment/mseh...
I feel like this would describe me to a T.
