Two 90 minutes lessons weekly. During the first part the professor introduces the subjects to be analyzed (theory), and through the second part the students should resolve problems, whose correction is made immediately and individually (when the number of students permits) by the professor.
In the case of laboratory sessions, students should previously study the procedures, in order to take the best profit from the experimental work.
The students can obtain procedures, and other study materials through the net.
The students are strongly advised to read the recommended bibliography, and do not base their study on the professor’s slides.
Final exam (66 %)
Lab reports (33 %)
