The examination consists of an oral examination or a written multiple choice test composed of thirty items. Each question is associated to four response alternatives, only one of which is correct. The correct response entails attribution of one point, the wrong response (or more responses given, or no response given) entails the attribution of zero points. In case of passing the written examination, the student can undertake an oral examination upon request, thus integrating the result hitherto obtained. The evaluation can be carried out in English upon request. Moreover, the professor can decide to carry out only the oral exam (e.g. in the case of online examination or with a low numerosity of students).
