A tutoring system is established with teachers through which students can contact via email or preferably via the Moodle platform (course forums). The tutors undertake that all queries will be answered within a period not exceeding two (working) days. If not, please resend the message to the same address. For questions of a general nature it is preferable to use the "Subject Forum" and thus "socialize" the questions and the answers so that all participants can benefit from both.
