There are two types of classes, theoretical and practical.
In the theoretical classes, the professors shall review the lessons of the program, organizing tutorials about them, and in the practical ones, several cases will be discussed and solved.
In order to make the most of the lectures, it is desirable that the students review the materials for each subject prior to the classes, as well as that attendance to practical classes involves, prior to the class, having read and studied practical cases provided for that week.
