Suoritustapa 1

2x2h lecture and 1x2h exercise session per week. Weekly assignments to be solved by the students and submitted for grading. It is compulsory for a student to be admitted to the final exam, to present their weekly assignments at least once during the exercise sessions. The final grade for the course will be calculated as follows: final exam (60%) + weekly assignments (40%).

Suoritustavan kaikki osat ovat pakollisia.
