Completion conditions

Assessment and completion of the course: Credit test and examination Continuous assessment: Student passes the continuous assessment and receives credits when he or she meets the requirement to obtain at least 16% out of 30%. The student will pass in PH and get a credit when he meets the condition to get min. 21% out of 40%. Credit To obtain the credit, min. 21 points out of 40 points. The student will receive this evaluation on the basis of a test of the issues covered and the submission of laboratory protocols (20 points) and the submission and defense of the project (20 points). Final assessment: Student passes the final assessment and passes the examination when he or she meets the requirement to obtain at least 36% out of 70%. The student passes the ZH and successfully passes the exam when he meets the condition to obtain min. 31% out of 60%. An exam To obtain the exam, min. 31 points out of a total of 60 points. The exam consists of a written part (basic knowledge test) and an oral part (theoretical knowledge of digital communications). CH is the sum of evaluations obtained by students for the evaluated period. The overall result is determined in accordance with TUKE's internal regulations. Overall assessment: Overall assessment is the sum of the assessments obtained by students in the assessment period. The overall result is determined in accordance with the internal regulations of the Technical University in Košice. (Study Regulations, the internal regulation principles of doctoral studies)
