Planned learning activities and teaching methods
Techning methods include lectures and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write a single project during the course.
Assesment methods and criteria linked to learning outcomes
Evaluation: 2 tests (up to 12 points for both tests), 5 laboratory exercises (up to 20 points) and 1 individual project (up to 8 points). The test has a compulsory written part (up to 40 points) and a compulsory oral part (up 20 points). The content of the exam corresponds to the subject annotation.
