The attention to the students will be done jointly and / or personalized. It is preferred to answer doubts jointly as it helps the class to be more interactive and that other students who do not dare to ask receive the same answers. Even so, 6 fixed hours are planned for individualized consultations in the teacher's office (will be announced on the first day of class). Apart from the established hours, the student may try to contact the teacher at any time in the office and, if available, resolve their doubts about practices or problems or theory
