Regular attendance is expected. When you miss class, you not only miss out on your colleagues’ contributions to class — you also deprive them of yours. Excessive absences may have an adverse impact on your final grade for the course.
If you are ill or have some other serious reason for missing class, please let me know ahead of class time if possible, but in any case as soon as you reasonably can.
Unless there are very serious extenuating circumstances, you must be present for all country study presentations.
