The maximum course load for a student is not to exceed 18 academic units or a combination of 18 academic and billable equivalent credits. Science laboratories, clinical, and physical education courses will be counted as units. However, the student is still liable for the tuition. The Dean of Academic Affairs must approve exceptions to this 18-unit-maximum policy. Students requesting exceptions must present their latest transcript. There are two possible reasons for making exceptions: The student completed all 18 academic units or 18 billable equivalent credits attempted in the previous semester; A student who is not on probation needs additional units in order to complete graduation requirements.
