Academic Dishonesty and Plagiarism allow the instructor to take any action chosen by the instructor and allowed by University Policy (summary executions behind the engineering building are not permitted by University Policy). Plagiarism is the act of taking the work of another and representing that work to be your own. In this class plagiarism is most likely to involve copying another persons exam, or having someone take an exam or do homework for you. Working on homework together is permissible provided that it is active participation and not just copying. If you are "caught" during a test undertaking an action that appears to be looking at another persons paper or appears to be passing or sharing information that action is considered to be academic dishonesty even if there is no clear evidence that plagiarism took place.
University policy allows the instructor to take actions as drastic as flunking you in the entire course for a single action and submitting you to university authorities for expulsion from school. Lesser actions such as flunking you on a test or assignment or reducing your points are also permitted. The instructor reserves the right to determine the seriousness of the sanction based on his own judgment and makes no warranty that the decision will appear to all as fair or equitable.
