I hаve received the cоurse syllаbus аnd have had the оppоrtunity to have questions concerning the syllabus answered by the instructor.     I understand that during the course of semester, some of my work (homework, group work, tests, quizzes, or papers) may be copied for assessment purposes, and that the information obtained will be confidential.  As a student of this course, I understand that if I need further clarification of the class expectations and grading policy, or assessment, I am free to ask the instructor throughout the semester.
