Note: At the end of the semester, the points are summed up and one of the two options is determined based on the total number of points. If all tasks are completed on time and successfully, the student will receive the exam “automatic”. If the scores are not enough, the student passes the usual exam on the subject. Also, any student of the correspondence department can attend specially organized lectures directly at the Faculty of Economics and Management within two weeks prior to the session. During the year students of the correspondence department have two sessions – in the middle of winter and at the beginning of summer. Tuition is paid either before the new semester or on a monthly basis. In this case, the first semester is paid before the conclusion of the contract in full. Thus, distance learning has all the advantages of correspondence education, and it also has a number of advantages, in connection with which a large part of applicants prefer this particular form of training.
