Academic Integrity: All forms of cheating, falsification, and plagiarism are against the rules of this course and of Grays Harbor College. Students who are unsure what constitutes academic dishonesty are responsible for asking the instructor for clarification. Instances of intentional academic dishonesty will be dealt with severely. Disabilities: Students who have documented disabilities that require accommodations in compliance with the Americans with Disabilities Act should contact the Disability Support Services coordinator as well as the instructor of the course in order to ensure that together we create an optimal environment for educational achievement. W Day, the final day to officially withdraw from a course, is the Thursday of the seventh week (Thursday of the fourth week for summer quarter). Students who do not withdraw by that date will receive the grades they have earned, regardless of whether they are attending the course or completing the work. Students who are considering withdrawal are strongly advised to consult with the instructor, advisor and financial aid prior to withdrawing. The only withdrawals allowed after W Day are complete withdrawals from all courses. 8/7/2013
