Description
The exam has a written and an oral part. The written exam is delivered using the Exam platform provided by Polito, integrated with the proctoring tool Respondus. It is also possible to give an optional oral exam, according to the rules described below. The written exam will be given at the scheduled date and time, as communicated to students and will consist of two parts: Introduction to Electrical Engineering and Electrical Machines. Each part has a maximum score of 16 points. Each part has * 4 multiple-choice quizzes: 0.75 points per questions, -0.25 penalty points for errors * 4 short numerical quizzes: 1.25 points per questions, 5% of numerical tolerance allowed on the result * Solution of a written exercise with multiple questions: 8 total points. The written exercise is a classical exercise and must be solved on A4 pages, scanned or photographed and uploaded on the Exam platform in digital format.
Duration
The duration of each module is 50 minutes. There will be a break between the two parts. As an example: * Start Introduction of Electrical Engineering: 8:00am * End Introduction of Electrical Engineering: 9:15am * Max duration 50 minutes (increased to 65 for students with special needs) * Start Electrical Machines: 9:15pm * End Electrical Machines: 10:30pm * Max duration 50 minutes (increased to 65 for students with special needs) Permissible and non-permissible aids During the exam it is possible to use * a scientific calculator * pen, pencil, drafting instruments * blank A4 sheets (max of 3 pages) for the written exercise to be scanned and uploaded as previously described) * The exam is a “closed book” examination: no book or formula sheet is admitted. * Everything that is not officially allowed, must be considered as a non-permissible aid. Cheating is a serious academic offense. Students discovered engaging in such behavior during the exam shall earn a failing grade and their case shall be reported to the Academic authorities for further disciplinary actions.
Grading
The exam is failed if any of the following is verified
* total score (Introduction to Electrical Engineering and Electrical Machines) lower than 16 points
* partial score (Introduction to Electrical Engineering or Electrical Machines) lower than 7 points
The total score of the two parts will be limited to 30 points in case of higher score.
Oral Exam
Candidates with a positive total score have access to the optional oral examination that consists of a 1 or 2 questions related to the course program of both modules. In this case, the final score is the mean value of the written and oral exam.
To access the written and oral exam, it is necessary to independently apply through the official registration website. The oral exam will be given remotely, with the teleconference tool communicated to the students a few days in advance or in person, according to the University rules. The oral exam is
* mandatory for students with a non sufficient total score (16 or 17 points)
* mandatory in case of doubts regarding the written exam
In these cases the Students will be informed a few days after the written test
* upon request of the Students
A few days after the written exam the grades will be notified and students will be requested to fill out a form with the following choices
* I accept the grade of the written exam
* I ask to give an oral exam
* I withdraw my exam (in this case a fail grade will be registered)

The modules are integrated and coordinated, thus there is a common exam with the following assessment methods and criteria.
