Don't they have practical courses? Do experiments?
Soviet and post-soviet education systems were modelled after german ones, but lab practice makes around 30%. For more abstract topics, practice/discussion/seminars.
- lectures: final exam that accounts for 100% of your grade, and sometimes (possibly obligatory) regular homework
- practical courses / labs: how grades are assigned vary, sometimes this will be a "do a project in a team" kind of assignment, sometimes it's experiments where you are expected to write one or more reports
- seminars: you'll be assigned a topic (usually some recent, narrow scientific result, no wildcard giant topics here) and expected to write a report on it & give a presentation
The exact mixture depends on your course of study.
It depends on what you study. In my CS classes we had a few lab sessions where we had to implement small programs and sometimes even larger projects. However, a friend of mine studied chemistry and she never got to leave the lab.
