Written exam 3/5 4 Hours Letter grades All aids are permitted - it is not permitted to collaborate / get help from other people in working with the exam task

The project is a combination of individual and group assignments. The project groups are set up by the course instructor. There is no re-sit option on the project. If a student fails the project, they have to take this part next time the subject is lectured.All assessment parts must be passed in order to achieve an overall grade in the course.

Course assessment

There must be an early dialogue between the course coordinator, the student representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital course evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
