Learning Assessment

Learning Assessment Procedures

The exam consists of:
- a written test consisting in the study of a mechanical system with the methods studied during the course;
- an oral test based on knowledge of the contents, the relevance of the answers to the questions asked, the ownership of technical language, the ability to make connections between the contents of the program.
The final evaluation will be determined taking into account the evaluation of the due tests.
Learning assessment may also be carried out on line, should the conditions require it.
