The grade of the theoretical part is formed by a written final examination. The written final examination of the theoretical part may include: Solving problems of application of the acquired knowledge, Short answer questions etc.\r\n2. The examination of the Laboratory Exercises is carried out with the continuous evaluation of the laboratory skills and the theoretical knowledge that were acquired in the course by the method of continuous evaluation and submission of weekly assignments.","bib_textbooks":"1.
