A good professional university is not Donetsk, qualified workers and good people, but there are, as I call them, fanatics of their subject(you must and must know by heart only the subject read by the lecturer, the rest is negligible, you can not eat, do not work, do not wash, BUT you have no right not to know this subject, but in general it is a very good place)
In general, all people are pleasant, but the building is like at Hogwarts, it's not difficult to get lost from the habit. Especially when you have to walk between buildings, but the scale!
