Forms of Teaching

Lectures

One hour lecture is held each week.

Exercises

Exercises are held 8 times for 1 hour.

Laboratory

Each student conducts laboratory exercises independently on laboratory model.

Grading Method

   
By decision of the Faculty Council, in the academic year 2019/2020. the midterm exams are cancelled and the points assigned to that component are transferred to the final exam, unless the teachers have reassigned the points and the grading components differently. See the news for each course for information on knowledge rating.
