The difference between distance Universities (e.g., the UNED; the Open University) and the rest of Universities is that, in the first ones, the University is responsible for contacting the students and providing them with all the materials necessary for passing the subject, by studying those materials. That is not the case of the rest of Universities, such as the UDC, in which the student is responsible for contacting the professors; downloading the materials contained in Moodle and working with them; attending the classes and taking notes on what it said by the professors; following the written and verbal instructions of the professor; and studying all the materials referred to, in order to pass the subject. The students who do not attend some classes (including the ones with exemption for attending the classes), have the same responsibilities as the rest of students, although in this case, since they are not attending the classes, they are responsible for getting in touch with peers and professors, aiming to collect all the teaching material that has been alluded.
