Knowledge and skills grading criteria
All work is graded on the scale from 1 to 10.
6.2
Calculating the grades for the course
The resulting grade for the running check evaluates the results of student’s work and is calculated according to the following formula:
Отекущий = 0.9·Ок/р + 0.1·Одз ;
The students are required to participate in the problem sessions in order to be able to take the examinations.
The resulting grade for the final evaluation in the form of examination is calculated according to this formula (where Оэкзамен is the evaluation of the student’s performance at the exam itself):
Оитоговый = 0,8·Оэкзамен + 0,2·Отекущий
This grade which is the resulting grade for the course is written down in the student’s certificate (diploma).
