Planned learning activities and teaching methods

Teaching methods include lectures, numerical exercise and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

The course is evaluated by student’s activity in the lessons and it is finished by exam valuation.
Students can obtain:
up to 40 points from tutorial lessons (projects of numerical and laboratory exercise)
up to 60 points from the exam (practical and theoretical part).
Detailed requirements for completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated every year.
