Requirements to the exam -

Before beginning any laboratory work, students are tested in writing.

The protocol for the laboratory work writing and casting process in electronic form within a week after completion of the work.

Successful completion of all laboratory work is a prerequisite for obtaining credit.

The exam is oral or written. A separate part of the test is to present and defend the project of technological measurements according to individual specifications. The questions in the exam include issues by syllabus and for study are sufficient background materials for lectures.
