Note: Note: Studying in full time at the university, the student acquires a stable and sound knowledge and practically at the end of each course, the “full-time” is an industrial practice, that is, there is an opportunity to go on internship in a good company, to prove itself and return to work there after the end of the entire period of training . If there is no such possibility, it is possible to take advantage of an internship practiced by many companies: that is, after defending a diploma, a student can go for 2-3 months to work for free. There will also be an opportunity to realize the knowledge gained at the university and stay in a good position. The benefits of getting education by distance are obvious. First, it reduces costs for the training process itself – renting a room, traveling to a place of study for students and teachers, consumables – paper, pens, pencils.Thirdly, often with distance education, students themselves can determine their schedule. At the same time, they can do not only at home, but also on the street, in a cafe, a park, while on vacation and so on. The main thing is to have a computer connection in this place. However, there are a lot of disadvantages to this system. First of all, this is a limited format of communication.
