Note: Even despite the numerous advantages of correspondence education, he has his own minuses. Extramural students should independently master about 70% of the educational material. That is, they are given only the basics, and the rest they study themselves. correspondence education lasts for a year more than full-time education. That is, while full-time students are preparing for the diploma, extramural students are only on the way to it and the restriction of certain privileges, which all the full-time students have, are also perceptible. For example, for part-time correspondence students, alas, the delay from the army does not apply, and all the possible benefits provided by the student card are completely absent. A scholarship was also abolished for part-time students. The student-extramural student can count not on the help of the state, but on his own financial resources and opportunities; and then all six years of training will fly, as one instant, without anxieties and worries.
