To pass the course the student must pass the labs. In addition, the student must complete either of the following two options: 1) Work actively in exercise sessions and submit homework solutions, but this can only yield the highest final grade of 3. 2) Take the final exam in which case any grade 0-5 is possible. The exam is preferably completed by taking minor exams. Bonus points are awarded from the labs, from working actively in exercise sessions, and from succesfully completed homework solutions. |
