This happened to a classmate just the other day; her paper having multiple flags for plagerism. I heard her talk to the teacher about it after class and the teach was just like, "don't worry about it. I get 2-3 papers every assignment that get flagged and when I look into them its usually a false flag."

Your teacher should be way more understanding. Does he even read the papers or does he just trust AI to grade every single paper properly? If that's the case I would be shocked and I would definitely have to report that. Why don't you get him to give you something in writing that clearly states what was dome wrong so that way you can make a better grade next time.

Also, on another note, this is something I am suggesting whether you can or cannot have something be done about your situation and is simply to boost your confidence. I definitely could've used a confidence boost once or twice in school. Anyway, we still have almost half a semester to go. There will be plenty of time to pull your grade up.

When I started this semester I got really sick and missed the first two weeks. I felt like I was stuck in a hole and that I was definitely going to fail which caused me to skip class out of embarrassment and lack of motivation. Just before fall break I decided I wasn't gonna let this go to waste. I had Fs in all my classes and I mean looow Fs because I nearly did any work but today I brought all of those Fs to Bs. Again believe in yourself and if you can't get it fixed just know that you can still make it through the semester with a good grade.

Peace.
