Teaching methods

Teaching is by classroom lectures on the topics indicated in the programme. During the course, the student can sit a total of two in-course tests that consist of writing answers to the questions in questionnaires handed out by the professor. If the student passes the tests and considers the result satisfactory, the result of the written tests will be considered valid for defining the mark/grade in the final oral exam.

Assessment methods and criteria

The exam consists of a written part followed by an oral one.
