Type of evaluation

The exam includes a written test and an oral test. The written test can be anticipated during the period where lectures are given and in this case it is spilt in two parts, the first related to the part 1 of the program, the second related to the part 2,3 and 4. Each test last 3 hours. Alternatively, the student can give a single written examination, there are 2 possibilities for each session of exams. The duration of the examination is 3 hours like in the previous case, but the test includes arguments discussed in all 4 parts of the program. The written test includes excersizes that are used to test the ability of the student to use the concepts that he has learned to solve real physics problems in electromagnetism: like the calculation of magnetic and electric fields, the computation of the charge and current variation in a circuit, the propagation of light through an optical system. The oral part is typically 30 minutes long, and it is used to verify that the student has learned the basic notions of the course and he is able to demonstrate the most relevant theorems. The oral exam evaluates the level of understanding of the concepts deployed in the program by the student, the acquisition of the proper language and terminology of the field, the clarity in the exposition and the ability to produce deductions from what has been studied.
