Teaching methods
The course includes lectures taught by the professor, and exercises including a project done by the students.
Periodically during the course some lessons are carried out interactively (or in flip-mode), presenting questions to which students must answer in relation to the program seen up to that time.
Assessment methods and criteria
The exam consists of a written and an oral test. Written and oral tests are held on the same exam day. The final mark is the overall evaluation of both written and oral tests. It is possible to vision and discuss the written test manuscript(s) only during the oral test. If written test average mark is insufficient (below 18 out of 30) the candidate must skip the oral exam and take the whole test again on a following exam session.
The validity of the written test score is limited to the current exam session.
