General:
WARNING: Our policy on excused absences has changed. If you exceed the maximum number of allowed excused absences, you will not receive course credit - you will have to request an “INC” and make up the missed material.
For more detail, see the Course Description page.
Make sure that your absence is excusable before deciding not to take the exam, because your grade will suffer less if you take the exam and do poorly than if you don't take it and get a 0.
