Good afternoon Ahmad,
I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today.
While you can argue that it was a mistake and that you did not intend to violate plagiarism rules, unfortunately, in the end it is up to the student to know what constitutes plagiarism and to avoid it. This not something that a college professor should have to teach a student. By the time you reach college of you don't know what plagiarism is, then you have a problem. You could have, and should have asked about it if you were unsure---or better yet done some research and learned about it, as well as how to avoid it.
The fact that it was a mistake and a result of you not understanding what plagiarism was or what an outside source was and how to properly identify that source in your paper does not make this not plagiarism.
I am very sorry, but most colleges give F's for plagiarism and while it may not be fair, it is what typically happens if you are caught not giving proper credit to other authors for their work in your college papers.
I understand that you may be disappointed by the Answer you received, as it was not particularly favorable to your situation. Had I been able to provide an Answer which might have given you a successful legal outcome, it would have been my pleasure to do so.
If you have additional questions, you may of course reply back to me and I will be happy to continue to assist you further until your questions have been answered to your satisfaction.
Would you please take a moment to positively rate my service to you based on the understanding of the law I provided by clicking on the rating stars---three stars or more. It is that easy. That is the way I am compensated for having helped you.
Thank you in advance. I wish you the best in your future,
