You'll get the most benefit from your classes if you attend class regularly and are on time for all classes.
The college attendance policy states that you cannot miss more than 1/16 of the hours the class is scheduled to meet (that equals the number of clock hours the class meets in a typical week), therefore you cannot miss more than 3 classes totaling 9 hours. If you are late to class three times, or leave class early, that equals an absence.
If you are absent or late beyond the course requirements, the instructor will decide if you can continue in the class, and will notify you of his or her decision. You can ask to be readmitted and, if denied, appeal the instructor's decision to the instructor's supervisor, whose decision is final.

You are responsible for making up all missed class work and for coming prepared to the class following the absence. You are responsible for letting the instructor know why you are absent and for initiating a contract to complete missed course work in a timely manner.
