examMode

Rules for the examination of PHYSICS II:
1) The exams take place in three sessions: winter session, summer session, autumn session.
2) The summer and winter sessions include three exams data, the autumn session two. Each exam data consists of a written test and an oral test.
3) To take the oral exam the mark obtained in the written test must be at least 18/30.
4) The validity of a written test passed to support the oral one is limited to the session in which it took place.
5) The student whose written exam has been assessed as insufficient will be able to take part in the next exam data of the same session, only if there is an interval of at least 25 days between the two written tests. This limitation does not exist if the student, deeming his written test insufficient, withdraws from the student by writing "WITHDRAWAL" on the letterhead.
6) During the two course, there are four laboratories whose frequency is mandatory to take the exam. Each laboratory involves the drawing up of a report concerning the type of experiment performed, which must be delivered at the end of the exercise itself. Each report is evaluated by a judgment (A: Excellent; B: good; C: sufficient; D: not enough).
7) The final grade of the exam will be based on the evaluation of the written test, the oral exam and laboratory reports.

examMode

A written exam, with 6 theory questions and 3 exercises, those answers determine the passage to the oral examination. Who receive a positive evaluation, at least 15 of 30, is admitted to the oral examination (required for passing the overall exam).
The oral examination starts with the discussion about the writing, with a subsequent assessment of the preparation on all program parts. Normally, the oral exam takes place two or three days after the positive evaluation of the written exam.
The exam tends to check that the student has become familiar with the manufacturing processes of metal components and, for this purpose, there are questions about hypothetical manufacturing cycles of real mechanical components, which are not necessarily treated in a specific lesson. In this way it is possible to evaluate the degree of obtained familiarity with the manufacturing processes and the mechanical characteristics deriving from production cycles.
