Grade «A» (excellent) is put in the case if student during a term showed perfect knowledge of all program questions of course, and also of subjects of independent work, regularly handed over midterm tasks, showed independence in studying of theoretical and applied questions according to the main program of studied course, and also on extra program questions.

Grade «A-» (excellent) stipulates perfect knowledge of basic laws and processes, concepts, ability to generalization of theoretical questions of course, regular handing of midterm tasks of classroom and independent work.

Grade  “B+” (good) is put in the case if student showed good and excellent knowledge of course questions, regularly handed over term tasks generally on “excellent” and some on “good”.

Grade “B” (good) is put in the case if student showed good knowledge of the questions opening the main maintenance of a concrete subject of course, and also subject of independent work, regularly handed over term tasks on “good” and “excellent”.

Grade “B-” (good) is put to a student in the case if he well is guided in theoretical and applied questions of course both on classroom, and on AL subjects, but irregularly handed over midterm tasks and had cases of a repeating an examination of term tasks on course.

Grade “C+” (satisfactory) is put to a student in the case he owns questions of conceptual character by all types of room classes and AL, can open the maintenance of separate modules of course, hands over on “good” and “satisfactory” term tasks.

Grade “C” (satisfactory) is put to a student in the case he owns questions of conceptual character by all types of room classes and AL, can open the maintenance of separate modules of course, hands over on “satisfactory” term tasks.

Grade “C-” (satisfactory) is put to a student in the case student during a term regularly handed over term tasks, but concerning room classes and AL owns only the general concepts and can explain only separate regularities and their understanding within a concrete subject.

Grade “D+” (satisfactory) is put to a student in the case he irregularly handed over term tasks concerning room classes and AL owns only the general concepts and can explain only separate regularities and their understanding within a concrete subject.

Grade “D-” (satisfactory) is put to a student in the case he irregularly handed over term tasks, concerning room classes and AL, owns the minimum volume of knowledge, and also allowed admissions of classes.
