In some universities, the correspondence form is a way to avoid expulsion from the university, since the requirements for students are much lower than on full-time education. Students with a disastrous failure usually offer a transfer to the correspondence department with preservation of the specialty and results of the passed disciplines. The first session for part-time students is for familiarization.
