Academic misconduct experience anyone?

I have been notified by my instructor this evening that a paper I turned in was plagiarized and a case is going to be filed to COAM. I have used several online plagiarism checkers and after seeing that it was safe, I had turned it in and this still happened… i am very confused and scared myself since I honestly do not know what I copied and plagiarized and if I was copying something, I thought that I cited it. I got a bad grade for this course and was repeating it so I really do not want to fail… if i were to be failed, can I repeat this course one more time? ( then Im taking this course three times; i am in the first semester of my second year)? what would happen to me now? What should I do? What are the processes? Please help me I am desperate

Dude, give me a break. You plagiarized, you got caught. End of story. If it’s serious enough to go to COAM, then it’s serious. Professors don’t just pull plagiarism out of the air. Seriously, why were you even using plagiarism checkers if you’re convinced you didn’t plagiarize? Ugh, people like you. Lies, lies, lies. You don’t know when to stop lying.

Admit that you plagiarized and move forward. They won’t kick you out if this is your first offense. You’ll receive an E for the course, though.
