I am in my last semester of undergrad. I am a full time student and a mom. I am also a straight A student. I work very hard. Anyways, we are in week 7 of the semester. Earlier this week my professor graded an assignment and gave me a 0. Based on some past announcements she made, it is because she things I used some AI thing called chatgpt (?) which I had never heard of until she mentioned it. I have to meet with her tomorrow. I am really upset. I know I didn't cheat. It doesn't make sense that I would complete 5 weeks of work, get 100% on all those assignments then suddenly cheat? I am an anxious, awkward, and emotional person who hates confrontation so I am a bit nervous about tomorrow. This sucks! Every week this professor mentions not to plagiarize or cheat and every week she seems to find someone who supposedly has. I entered my work into multiple AI detectors and they all had different scores. I really don't think they are reliable.
