Forms of Teaching
The examples are solved during the lectures.Seminars and workshops
Seminar is mandatory.Laboratory
Laboratory experiments are on Department of applied physics. Laboratory is mandatory.
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.
