A few months back, my math class was given an extremely hard take home test. We were told we were allowed to use our textbooks and notes in addition to asking the teacher questions. We weren't allowed to talks to each other or use the Internet. Of course I knew some people would cheat. However every single person but me in the class cheated. I have messages in the group chat to prove over half of them. I ended up doing very poorly then working my but off to do corrections (which my teacher graciously allowed me to do to help bring my grade up) while the people who cheated got 100's and were applauded by the teacher during class. I got extremely mad, but did not rat anyone out. I felt bad because it was a group of highly intelligent students being extremely stupid and I'll admit that a lot of them are my friends.
We were given a take home final over the break and the same thing is bound to happen. I'm not sure really what to do. One thing I'm concerned about is that I could be convicted for just being in the group message with the people cheating on it. The thing is it's our class group message for everything and it shows you when someone leaves it so I don't want to just randomly leave it. It's also the injustice is really starting to get on my nerves. I'm think that if they start to cheat on the group message I'm going to leave it and maybe just say to the teacher that I overheard some people cheating without saying names and let him handle it. I'm also a little bit worried about getting convicted because I was on the other group message that there was cheating materials on. I got a super low grade on it and didn't even comment on any of the cheating stuff so I think that's just me being paranoid. What do y'all think I should do?
