24 hours of lectures organized as follows: online exercises + group exercises in the presence. The compulsory attendance of at least 70% of the hours is foreseen.

Written exam with closed questions (multiple and open answers) and exercises.

The grade is expressed out of thirty and the exam is considered passed if the score is greater than or equal to 18 (2 additional points are provided to obtain honors). This score, by means of a weighted average together with the marks of the other modules, will contribute to determining the overall mark of the Teaching. Unanimous praise can be granted in the teaching grade, if the final grade is 30.
