Opportunities for Formative Feedback

Opposition and check-up seminars for each of the five hand-in group assignments where held where the student groups critically reviewed each others codes.
A report for each of the four first assignments was handed in and reviewed by academic staff.
The fifth assignment was presented by the groups for the rest of the class orally using slides.
An individual oral examination was held at the end of the course.
