Academic Honesty

Review the class announcements and resources related to academic honesty and avoiding plagiary. Make sure that your application does not plagiarize from other authors. Recognize that whenever passages written by other authors are used in your work they must be enclosed in quotation marks and the original source must be cited. Applications demonstrating plagiary are worth zero points.
