Assessment methods and criteria: Current monitoring of practical classes is carried out in order to identify the student's readiness for classes in the following forms: • oral survey before the start of classes; • assessment of the student's activity in the course of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc.; • surveys and reports during the practical session. Examination control is carried out in the form of a written and oral survey and/or test control. The final control is carried out based on the results of the current control and semester examination control.
