Assignments are graded towards the course mark. Unless specified otherwise, assignments are to be sent in by e-mail. Details of the assignments will be provided on separate handouts or on web pages, to be accessed through the course homepage. If an assignment is not handed in on time, you will need to explain the circumstances to the course co-ordinator, Peter Verhaar, or to the co-ordinator of studies, Jurjen Donkers, at least one day before the assignment is due. If assignments are submitted after the specified deadline without a valid reason, 0.5 will be deducted from your score for each day that the assignment is overdue.
