Good professors, but so unorganized it stifles learning

The professors in Minsk Linguistic University are really good and always try their best, but it feels that the administration is actively working against them and the students. Foreign students are treated as cash cows, and any complain you have will be met with derision and gaslighting unless you throw a fit. I've seen students asking to be moved to a different group because of their level and being refused, saying that they had done a level test and couldn't move just willy-nilly. And I've seen students saying that they were paying for the classes and demanded to be moved to be close to a friend, and the university just giving in. In the summer, that happened at least one a week, meaning there were always people coming and going from the group, and a lot of frustration over the way the university awards bad behaviour. At one point, a student became part of my group even though he had tested much lower, and would shout at the teacher whenever he didn't understand what was going on, forcing the prof to constantly have to stop and deal with him. Our productivity (by chapters of text book Zhili byli done by week) felt by over 50%, all students complained repeatedly, and the administration refused to do anything about it, saying that he has paid for the classes, as if the rest of us hadn't. They kept saying that whoever was unhappy could move, until we decided that we would all move together then, which they then tried to forbid. Situations like that were very common here.
