Cheating and Plagiarism Policy

I expect all students to uphold the principle of academic honesty. Cheating and plagiarism (presenting another person’s words or ideas as one’s own) are not acceptable behaviour at anywhere. Depending on the severity of the offence such acts can result in a grade of zero on the test or assignment, a failing grade (F) in the course, or expulsion. In all cases, the circumstances and the penalty are recorded in the student’s file.
