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, reports and presentations during the practical session. Examination control is carried out in the form of a written and oral survey and/or test control, which may contain: written and oral theoretical questions of an open type, practical tasks and tasks, test questions. The final control is carried out based on the results of the current control and semester examination control.
