Course grading

The assessment of the course consists of a written exam (60% of course grade) and a practical part (40% of course grade). The practical part is subdivided in (1). Visual analytics assignment (10%); (2) Feature extraction assignment (assignment 2) (10%); (3) Final assignment (20%). The grade for the written exam should be 5.5 or higher in order to complete the course. The weighted average grade for the practical assignments should be 5.5 or higher in order to complete the course. If one of the tasks is not submitted the grade for that task is 0.

The assignments are completed in groups of 2 students.

A submission after the deadline is counted as re-sit. When submitted as re-sit, the maximum grade for an assignment is 6.
