Assessment methods and criteria: The main methods of knowledge diagnosis are: current (PC) and semester control (SC), which is carried out from educational material, the scope of which is determined by the work program of the discipline for the semester. Current control is carried out during lectures and laboratory classes in order to check the level of assimilation of theoretical and practical knowledge and skills of the student. PC is conducted in the form of: written and oral control and defense of laboratory work. Semester control is conducted in the form of an exam (EC). The exam is a form of SC of the results of the student's studies in the academic discipline for the semester.
