Learning Assessment

Learning Assessment Procedures

The exam consists of a written test and an oral test. The written test consists in solving, in two hours, two exercises concerning the exam program. The written test is passed with a score of 15/30.

The oral test consists in the discussion of the written test and in an oral interview to verify the knowledge of the topics covered during the course.

The final evaluation of the exam, based on what has been verified in the written and oral tests, is determined by the following criteria: level of knowledge of the required topics, expressive ability and language properties, ability to apply knowledge to simple case studies ( as emerged in the written test), ability to connect the different themes of the teaching program.
