Lectures are organized through two cycles. The first cycle consists of 7 weeks of classes and mid-term exam, a second cycle of 6 weeks of classes and final exam. Classes are conducted through a total of 15 weeks with a weekly load of 4 hours.

Mid-term exam in the 8th week of classes and final exam in the 15th week of classes.

Consultations are held one hour weekly according to arrangement with students.
