Teaching Methods theoretical lessons and exercises
Evaluation methods Verification of learning:
The exam consists in a written exam followed by an oral exam. The written part, one hour duration, needs the solution of two exercises similar to those executed in the course, regarding the full course program.
The questions in the oral exam require to illustrate orally, with the use of a support (paper or blackboard), arguments regarding the full course program. The oral exam must be performed necessarily within the same session of the written part.
