Note: The terms of distance learning entirely depend on the specialty. As a rule, the term of study in absentia is about 5.5 – 6 years depending on the specialty, which is 6 to 12 months longer than the full-time study. But if you get a second higher education in correspondence department, you can be enrolled immediately to the third year, and then the term of study will be 3.5 – 4 years. In addition, there is always the opportunity to take exams externally, reducing the duration of studies even more, but this will require a very high level of self-organization and discipline. On the correspondence form more often people are trained who combine study with work. So, the student learns longer, but the university also visits much less often, namely, during the installation session and during the examination period. In the first case, teachers lecture, provide a plan – summaries, give topics of coursework, abstracts and approximate questions for the exam, and also prepare the student thoroughly for the forthcoming session.
