Type of Assessment
The exam consists of written and oral tests.
Written test
Written test contains exercises on the topics covered in the course. A separate written test is carried out for part I (Mechanics and thermodynamics) and part II (Electromagnetism). The written test is to be repeated if the mark is less than 17/30. In the case of repeated written tests, the test mark is that corresponding to the last written task delivered by the student.
Oral exam
The oral exam is compulsory if the result of the written test corresponds to a mark between 17/30 and 20/30, it is optional from 21/30 to 30/30. It is possible to carry out a global oral test including the entire program of the course or to carry out a separate oral test for part I (Mechanics and thermodynamics) and for part II (Electromagnetism). In this case, the final mark of the oral test is given by the average of the two marks obtained in these partial tests.
