Note: There are some disadvantages: in the diploma, as a rule, indicate that you received your qualification by going through the external studies at the university; in the post-Soviet space, it is generally accepted that the quality of education in correspondence courses is lower than in full-time education; not all students are able to independently learn the material, as well as have a large share of self-control and perseverance; not every profession can be mastered by studying external. So, the majority of technical and creative specialties, where long practical lessons are required, do not have something like external studies, but even extramural studies. Before deciding to study in the external, think whether you really need it, and most importantly – whether you can master the profession almost independently. The learning process is as follows. The student is given a curriculum, exemplary questions for studying and the amount of knowledge that is necessary for the successful passing of the certification. Depending on the program, the training course may include lecture classes, or may be absent.
