Learning activities and methodology
Theory (3 ECTS): During theoretical sessions, the contents of the course will be introduced, explained and illustrated with examples. Teaching materials will be provided on the Internet. Practice (3 ECTS): During practical sessions, black-board exercises will be solved. Software-related activities will take place in the computer labs. In the 15th week of the term, a group-review session for the final exam will be held.
