What is it?
Plagiarism of Authorship is turning in someone else's work and passing it off as your own.
According to Rutgers...
"Submitting a purchased or downloaded term paper or other materials to satisfy a course requirement" is considered cheating.
"Submitting as one's own work a term paper or other assignment prepared, in whole or in part, by someone else" is considered cheating.
