In the third semester of study, students prepare their postgraduate thesis with the obligation to complete it during its duration. However, if there are demonstrably important reasons, the possibility of an extension for another semester is given. The postgraduate diploma thesis is publicly defended before a three-member examination committee, which is appointed by the GSE and in which the thesis supervisor and two other members-teachers of the PGS participate.
With regard to the issue of the teaching and research employment of postgraduate students, it is emphasized that the Postgraduate Students will be able, following a decision of the Special Composition General Assembly of the Department and the Coordinating Committee, to assist Professors of the Department in tutorials and workshops of Undergraduate Study Program, as well as to participate in research projects and programs related to their scientific subject. Finally, in the framework of the PGS, in addition to lectures and lectures, theoretical and laboratory exercises are provided with the help of new means of communication and new technological methods, presentations by students and visits to relevant workplaces.
