Teaching methods
The theoretical topics of the course are explained by means of lectures. Exercises are also proposed in the course.
Assessment methods and criteria
Written examination which consists of 4 questions to each of which are assigned up to 7.5 points. Students who gained at least 18/30 in the written examination may apply to take an oral supplementation (which will account for 50% of the final grade), or verbalize the mark of the written test.
