Proper notification requires that you call the appropriate curriculum office at the beginning of the school day stating your inability to attend class. An alternative is to have someone else call for you. Each unexcused absence will result in a zero for that day which causes a reduction in your overall average per day. In addition, three points will be taken off of the student's final grade at the end of the semester for each unexcused absence. Arrival later than that is considered an absence.
Early departure is considered leaving before excused by the instructor.
If a student arrives for class and lab, then leaves early, these will also cost one absence. Some types of work such as group projects typically cannot be made up. In all cases. Lab work, quizzes, or exams cannot be made up from days with unexcused absences. Missed work will receive a grade of zero.
