Learning assessment procedures

The exam is aimed at verifying the level of achievement of the training objectives of the course. In particular, the exam consists of:
1. Brief interview about projects based on classroom exercises
2. Oral exam on the topics presented during the course

The exam is passed if both phases are considered positive
