- Syllabus of tutorials:
-
Exercise classes represent an integral part of the actual lecture. Whenever some logically consistent part of the lecture is finished, the students are asked to demonstrate their understanding in front of a blackboard. Inasmuch, the content of the exercise classes is identical with the content of the lecture.
