Assessment methods and criteria: Assessment of students 'knowledge is conducted in the form of semester control, which is conducted at the end of the semester and includes the results of current control of students' knowledge, which is assessed by laboratory work, oral examination and control event - the answer to the ticket. The control event is a mandatory type of control and is conducted in writing and orally at the end of the semester. Current control (45%): Results of protection of laboratory works, performance of complex work, oral interrogation. Final control (55%, exam): testing, survey.
