Assessment methods
- modality: oral exam (unless otherwise specified due to the pandemic condition in place)
- evaluation parameters: ability to discursively organize knowledge; critical reasoning skills on the study carried out; quality of exposure, competence in the use of specialist vocabulary. The questions will focus on both the theory part and the exercise part with the request for numerical resolutions.
- the type of evaluation used: mark out of thirty
- number and types of tests that contribute to the final assessment: Final oral exam. There are no intermediate tests during the course.
- any materials useful for taking the test and allowed during it: calculator. Consultation of notes / texts is not allowed.
