In plain English, you have to complete the course yourself. In legalese, it sounds a bit scarier but ultimately means the same thing:
"No credit or completion will be given if the course is completed by anyone other than you, or if you are assisted by an outside party. When you enroll in the course, you are stating under penalty of perjury that you, and not another person, studied the material in its entirety and completed the chapter quizzes and the final exam. By registering for the course, you understand that it may be a felony to make false statements or to falsify documents submitted by the court."
