Learning activities and methodology

14 theory classes with supporting material available on Aula Global, which this academic year will be in synchronous online mode through the Blackboard Collaborate platform, and 14 face-to-face practical classes including problem solving sessions and virtual computer labs accessing through laptops in class. No group tutoring sessions are foreseen except possibly during the class-recovery week at the end of the semester.

Assessment System

- % end-of-term-examination 50
- % of continuous assessment (assigments, laboratory, practicals...) 50
