Grade formation

No exam.

Final mark is computed based on four units as follows:

· Classroom exercises, 40% of the mark

· First laboratory work, 10% of the mark

· Second laboratory work, 20% of the mark

· Third laboratory work, 30% of the mark

All four units must be passed otherwise final mark is not given
