Most of universities, following the Russian system, focus entirely on teaching and do not engage in research. Students who are accepted to university at any level apply under a specific major, and the curriculum is set by the university (according to State legislation) for each major. For example, economics majors will all study in the same courses in the same order, separate from English majors who have a different curriculum. Some courses are required for a variety of majors and there is a possibility of switching majors but typically classes do not transfer to the new major and the student is expected to reenter in the new major as a first year.
