Students are expected to attend all classes in all courses for which they are registered. Individual absences, dropouts and leaves will be treated on a case-by-case basis. Students who have not completed required assignments will be awarded an “I” grade. Normally this is regarded as a temporary grade; the deadline for the completion of the work is no later than 6 weeks after the end of the term. If the work is not completed by this time, the “I” becomes a permanent grade and the course will neither be counted towards graduation nor be computed in the cumulative index.
