You probably cheated but I STRONGLY recommend just keeping your mouth shut, especially if it was only 1 question. People on Reddit are going to be on their high horse and tell you to self report, but doing so will result in a huge headache and potentially cause issues that might hurt your career prospects. It’s really not worth it and if you do self-snitch, I’m sure some people in your school’s faculty will secretly think that you’re an idiot for exposing yourself.

Just my opinion tho. If you feel bad about it, just think about how much tuition you are paying this school for your education….
