The contents of the syllabus and the support material for the study are in the Moodle platform of the UDC, so it is essential to connect to it, and pay attention to the news that both teachers and automatic servers will disseminate throughout the course. It is advisable to keep up to date with the material, attending classes, answering the questionnaires and solving the complementary exercises of the different topics. It is very helpful to understand written English, since most of the bibliography is in that language, and to know how to use EXCEL sheets at user level.
