Teaching methods and general organization

— Lectures. — Presentation of assignments by students to the rest of the class.

Official assessment of learning outcomes

Assignments proposed to students (optional) and oral presentation (15 minutes) in front of the class.

Examination-based assessment

Single assessment consists of a written examination to assess student progress.

Repeat assessment criteria

Repeat assessment takes place in June and consists of a written examination to assess the improvement in student progress. The final grade includes proposed assignments (optional) and oral presentations carried out by students throughout the course (20% of the final grade).
