Students’ evaluation
A modular subject with individualized roles is given during the semester, which is delivered and graded. At the same time, a presentation of the topic is made by the students, which is also evaluated. Cumulatively, the subject covers 50% of the final grade. The written exam covers the remaining 50%.
