I do not know of any other student who has given or received help during this test.
I will report as soon as possible any suspicious, dishonest, or unethical conduct related to this test to a proctor, a teaching assistant, Dr. Kite, or the head of the Department of Geology and Geography.
Any form of academic dishonesty will be fully pursued by the staff and members the department, the College of Arts and Sciences, and WVU. Penalties may include assignment of a grade of "unforgivable F", or worse. Theft of tests or unauthorized intrusion into computer accounts or files may be pursued through criminal codes.
I understand that this class has "zero-tolerance" of academic dishonesty.
You may get a zero if all of these are not filled in correctly!
