I am thinking about sending this to her:
Dear Mrs. --------,
"When plagiarism/cheating is discovered or suspected, there will be immediate intervention by
the teacher. The student will appear before the teacher for a private conference to ascertain the
facts of the situation. Students who have plagiarized may receive a zero for the assignment." - Student Handbook
Acknowledging the fact I like a good B in English, rather than a C or a D (I don't fully understand/acknowledge the weighing system you are going to use), I looked at the handbook and I saw this:
"Students who have plagiarized may receive a zero for the assignment." Keyword being "may". Due to the low severity and ratio of the plagiarized material compared to my own work, the other material in my book report is confidentially credited to my own thoughts. I was thinking that you can kindly review this with the administration as I really don't want to get a zero percentage.
I can still accept the fact of keeping the zero percent, but anything otherwise is acceptable in my terms. Everything is better than a zero.
