The teaching-learning methodologies include various instruments, based on masterly/tutorial teaching and theoretical-practical, face-to-face teaching. Other non-face-to-face instruments (e.g. Moodle) complete and diversify the options available. The theoretical-practical classes aim to deepen and practice the topics taught in the theoretical classes, thus providing more direct contact with these topics. The assessment system is preferably continuous and consists of 2 written tests (45% each). Attendance at theoretical-practical classes and participation in solving the proposed exercises count towards the final grade, contributing 10%.   The final exam system applies to students who opt for it, students who fail the continuous assessment, and those who request a grade improvement, covering the entire syllabus
