Student Responsibility to Drop/Withdraw: It is the student’s responsibility to officially add, drop, or withdraw from the course stated in the class schedule. Failure to do so can result in a failing grade.

Class Attendance: During the first two weeks of the semester, you will be dropped for missing any class. After that, a student may be disenrolled from the course after two absences; however, a student will be disenrolled from the course after eight absences without exception. ATTENDANCE IS VERY IMPORTANT FOR THIS PARTICULAR COURSE.

Tardiness/Early Departure: If a student arrives unreasonably late or leaves early without notifying the instructor before the event, then that student will be considered absent for that class session.

Professionalism: It is assumed that students will conduct themselves in a professional manner with a positive attitude. An open mind is one of the most important tools required for success in academia. If a student is negative and feels as is there is nothing of value to be gained by the college experience or this course, he or she will not do well in this course.

Student Code of Ethics and Conduct: Students must abide by the Student Code of Conduct. Students who obstruct the instructor’s ability to convey knowledge, or disrupt their fellow students’ ability to learn, will be dealt with under the terms delineated in the Grossmont College Student Code of Conduct. Such dealings may include, but are not limited to, warnings, written reprimands, disciplinary probations, instructor-initiated suspensions, terminations of financial aid, short or long-term suspensions from campus, and temporary or permanent expulsions. These consequences are serious and can easily be avoided.

Examples of disruptive activities that will not be tolerated are: repeated cell phone ringing, repeatedly falling asleep in class, excessive talking, texting, passing of notes, entering and leaving class several times during a session, verbal rudeness directed towards the instructor and/or other students, and non-verbal rudeness directed towards the instructor and/or other students. Finally, ACADEMIC DISHONESTY IS GROUNDS FOR DISMISSAL FROM THE COURSE. If you are unsure of what academic dishonesty is, ask the instructor.

This instructor is charged with maintaining a positive learning experience for all students in this course, and that responsibility is a serious one. Disruptive behaviors will not be tolerated in this course.

Academic Integrity: Cheating and plagiarism (using as one’s own ideas, writings or materials of someone else without acknowledgement or permission) can result in any one of a variety of sanctions.  Such penalties may range from an adjusted grade on the particular exam, paper, project, or assignment to a failing grade in the course.  The instructor may also summarily suspend the student for the class meeting when the infraction occurs, as well as the following class meeting.  For further clarification and information on these issues, please consult with your instructor or contact the office of the Assistant Dean of Student Affairs.

Accommodations for Students with Disabilities: Students with disabilities who may need accommodations in this class are encouraged to notify the instructor and contact Disabled Student Programs and Services (DSPS) early in the semester so that reasonable accommodations may be implemented as soon as possible. Students may contact DSPS in person in room A-113 or by phone at (619) 660-4239 (voice) or (619) 660-4386 (TTY for deaf) or online at
