The final evaluation will be based on the following tests:
- final written exam, it is necessary to pass it to be admitted to the oral exam with an evaluation of at least 16/30;
- oral exam on the whole program. Three question, one for each main section of the program, will be randomly selected for each candidate from a set of roughly hundred questions published on the moodle web-site of the course. Each question will be evaluated with +/- 2 points on 30.
