As a teacher, I feel I need to come out and say now that I am not a shadow scholar. I do not write papers for students. I have never written a paper for a student.
However, once I did completely re-write a paper for a fellow student when I was in college. It was the summer, he was taking a marketing course online, he wrote a paper describing a plan to market and sell paper towels that “open easier” because there is an opening tear strip, everyone knew it’s easy to open paper towels by poking the top hole, and he had a lot to work on in terms of grammar and mechanics besides. So I completely rewrote his paper. The trade-off: He let me cleaned the lazer tag arena for me while I “edited” the paper.
