*Update* Teacher gave me a 0 on paper for misspelling authors last name, I'm scared I won't graduate.
Good News! I had a chat with my professor, and when she said the 0 was for attention, they meant that it literally was there as a way to give me a little scare and set up a meeting. We had a good discussion about it, and she emphasized that it was a real paper, but the misspelling was a red flag for possible AI use, so she wanted to have a chat with me. Everything is resolved, and she's grading the paper normally. I also found out she is dropping two of the discussions that I missed (which is course policy, but the syllabus had me confused), so I'm no longer worried about graduating.
Little heart attack, and probably could've been an email, but I'm glad we could sit down and have a chat about it, and all is resolved.
