as many tifu, this did not happen today, but about four years ago in my sophomore year of high school. 
i was taking ap world history, and the teacher for it was a real pain in the ass. everyone hated him. we had at least 3 hours of homework every night for his class. he was also really strict, and everyone was afraid of him. the one good thing he did was he made online practice tests (100 questions), and many of the questions were put on the actual test. 
about halfway through the year, i found an online version of the textbook. being lazy as i am, i decided to make a word document of all the questions and answers for myself to use to study from for the test. i would ctrl+f the question, find the answer in the book, and copy it down. 
a few weeks after i started doing this (and doing a lot better on the tests), i started sharing them with five of my (then) closest friends. i trusted them completely, the fool that i was, to not pass it on. 

a few months pass, and one day our teacher decides we are going to take the practice test in-class to prepare for our test and we could use our notes, and it would count for our actual test. word gets out, so by the time my period class has to take it, i had memorized my practice test. our teacher starts walking around, and after about five minutes, he starts yelling. this kid i had never talked to, never met, didn't even know his name, had a printed version of my practice test and he was using it on the test. i was scared shitless because i thought, oh my god, i'm going to get honor coded and suspended and this can't happen to me, i'm a good person. after yelling at us for the rest of the period, our teacher says that whoever made the practice test needs to come forward or else when he finds out who did it, they will be expelled. 

fucking freaking out, i go home for the day, agonizing over what to do. i text all five people who i sent the tests to, questioning them if they had released it. of course, all of them deny it. i finally decided to write our teacher a note explaining that i had made the test, i used it to study for our actual tests, and i only gave it to a few friends that really needed it, whom i trusted completely, and i had no idea how this kid had gotten it but i was very sorry and i would never to it again, etc etc. i left it under his door the next day. during my class period, he took me aside and he said he understood and that i was not in trouble. i was so relieved. the kid who had had the test got suspended, and that was the end of that.

fast forward four years, and i remember this whole fiasco. i start texting my friend, let's call her mary, that i'm still very close with. it turns out that *every single person* that had ap world that year had gotten my practice test. i asked people i knew in junior year that had had ap world, and yep, that had gotten them. one of best friends who i met junior year, she thanked me, because my tests made her pass the class. 

edit: italics problem. thanks sensitive-badger!
