Assessement methods and criteria
The examination consists in a written exam, followed by on oral interview. The written exam consists in the solution, in 2 hours, of 3 or 4 exercises on the topics treated in the course program. The positive outcome of the written examination is valid for the entire Accademic year and gives access to the oral interview At mid course and at the end of the course, two written examinations will be possible, each one concerning the solution, in 2 hours, of 3 or 4 exercises on half of the program. The positive outcome of both examinations will substitute the general written exam. The oral interview starts with the discussion of the written test and covers the entire program of the course.
