Furthermore, during the Course, there will be two written tests on the first (Cauchy continuum) and the second part (DSV problem) of the Course. The students that will pass them, will be enabled to access directly the oral exam. ASSESSMENT METHODS The written test is based on the solution of some (2/3) problems similar to those dealt with during the course exercises, concerning the whole program of the course. The use of books or notes, and electronic equipment of any kind (cell phones, tablets, laptops) is not permitted. The written tests are valid during the exam session in which they are sustained (June-September or January-February). Students who have obtained a grade equal to or greater than 18 in the written test are admitted to the oral exam. Handing in a test cancels the outcome of any previous written tests. The written partial tests proposed during the course (II semester), with an average grade equal to or greater than 18, replace the written test. The partial tests lose validity if the oral test is not sustained by the end of the Session in which they are held (September). The topics of the partial tests concern the contents developed in the periods preceding the test itself and concern the first (Cauchy continuum) and the second part (DSV model solutions) of the course. Handing in a test cancels the outcome of the partial tests. The oral examination is aimed at verifying the acquisition of the concepts and analytical skills acquired by the student and the knowledge of the theoretical part of the program, as well as a possible discussion of the written test. To take the oral test it is necessary to have a valid written test and to be in compliance with the prerequisites. If the outcome of the oral test is not sufficient, a new written exam must be taken. The exams take place in Italian. The oral exam can be taken in English.
