The exam is targeted both to evaluate the theoretical knowledge of the subject and the capability to apply that knowledge to the solution of practical problems. Therefore the examination consists in an oral test (three questions which may be theoretical ones or solution of simple exercises) and the final marking is the sum of the score obtained in each question.
No textbooks or notes are allowed during the written exam.
A computer with a webcam, loadspeakers and a good internet connection are required. The student must be visible during the whole duration of the exam.
If the exam is taken on site the modality will remain the same and the questions and the answers will asked and given in presence,
The final exam checks the acquisition of the following skills:
● knowledge and understanding of the listed course topics;
● the ability to apply theory and calculations to problem-solving;
● laboratory practical knowledge and technical report writing.
On the course portal will be made available exercises, some with solutions, to help to prepare for the exam. The exercises will be available in the course slides and notes, as separate documents in the Materiale tab of the course portal on http://didattica.polito.it/ or on the platform used for the online exams. In the latter case, some of the exercises will be structured and formatted as an online exam to help to get familiar with the platform features, controls, and navigation.
The blended final exam is written, both in the classroom and remotely, the latter using the Lockdown Browser and Respondus proctoring. The remote students should provide a computer with a webcam, loudspeakers, and a good internet connection. The whole student face and hands must be always visible during the exam.
The blended final exam can last up to 2 hours and 30 minutes. It consists of 4 problems and 9 quizzes from any of the listed course topics. The problems require applying the theory with calculations and are valued to a maximum total of 16 points. Each quiz has a question with four predefined answers, of which only one is correct. Correct answers receive 1 point each, while wrong answers receive 0 points. The quizzes can total at most 9 points. During the whole exam duration, it is forbidden to check any source of information (course notes, books, phones, colleagues or other persons, headsets, PC, etc.). Only non-programmable calculators are allowed.
The laboratory reports can give up to 1 point each. The grading evaluates the quality of the experimental setup, of the measurements, of the results, and of discussion, as well as the presence and involvement in the experiments. The laboratory grades are calculated on the best 5 reports for each student. If there are not enough reports available, the missing ones will be graded 0 points.
The maximum final grade is 30 points. It is made up to 25 points by the written exam and up to 5 points by the laboratory grade. To pass the exam, the grade of the written exam must be at least 60 % (15 points), and the final grade, including the laboratory marks, must be at least 18 points. The laboratory grade remains valid for final exams in any subsequent academic years.
A student can reject a passing exam grade only once. The next passing grade of a student is final.
Oral examination can be requested by the students to attempt to improve the exam grade, but only if they received at least 60 % at the written exam (15 points or more). The oral examination consists of up to 4 theoretical questions or simple problems to solve and discussions of related topics, aiming to ascertain the acquisition of the same skills as the written exam. Each topic of the oral exam is graded separately, using positive marks for good answers and negative marks for the wrong answers, including the answers to the discussions. The marks are then averaged and multiplied by 3/4 to obtain an oral exam mark of ±3 points. This is algebraically added to the grade of the written exam. The total should be at least 15 points, otherwise the exam is failed. To pass the exam, the sum between these points and the laboratory points must be at least 18.
Additional oral examination can also be requested by the professor whenever it is necessary to ascertain the knowledge shown in the written exam (e.g., when there are fraud suspicions). The structure of this oral exam is the same as for the one requested by the student. But in this case, the grade of the oral exam can only decrease the final exam grade by any amount of points or leave it unchanged, as follows. Each topic of the oral exam is graded separately, then averaged. The maximum possible grade from the oral exam is scaled to the grade obtained by the student in the written exam. The difference between the oral exam grade and the maximum oral exam grade, scaled as above, then is subtracted from the grade of the written exam.
Oral examinations can be either onsite presence or online.
