Criteri, regole e procedure per l'esame
The goal of the exam is to test the knowledge of the candidate about the topics included in the official program of Physics 1 and to verify the skill in solving problems. The exam consists of two steps: a written exam followed by an obligatory oral exam. The assessment of both the written and the oral part is based on marks ranging from 0 to 30 (the maximum is 30 out of 30 cum laude).
The final assessment is determined by the average of the marks obtained in the written exam and the interview.
Written exam: a mark less than 16 out of 30 in the written exam is not sufficient for the admission to the oral exam. The exam actually begins when a candidate enters the exam room. The exam of a candidate is recorded with "rejected" in two cases: If a candidate decides to stop his written
exam once the exam has started and if the assessment of his written exam is less than 16 marks out of 30.
Candidates are not allowed to take in the exam room text-books or notes relevant to the Physics-1 program. The use of electronic calculators is allowed provided these are cleared of all pre-stored programmes or information.
The written exam consists of 3-4 questions. In general, these are exercises with the same degree of difficulty of the exercises discussed in the Physics-1 lectures devoted to applications (esercitazioni).
Part of these questions, however, might be focused on the theory included in the Physics-1 program.
The exercises proposed in this exam are inspired by the exercises/examples contained in the textbook
used by the course lecturer. The text-book will be indicated by the lecturer at the beginning of the course.
Oral exam: students are admitted to the oral exam if the assessment of their written exam is 16 marks out of 30 or more. The assessment of oral exam cannot be less than 18 marks out of 30.
The exam is passed if the final assessment (average of the marks of the written and oral exam) is
18 marks out of 30 or more.
Oral exam is mainly oriented to check whether a candidate has a sufficiently wide knowledge of the theory of the Physics-1 program. Oral exam may include questions concerning the written exam of the candidate and his activity in the physics laboratory. The theoretical topics discussed in the course lectures are summarized in the program of Physics-1 courses of the Politecnico.
In general, the oral exam must be passed in the same exam session (appello) in which the written exam is passed.
