Requirements, evaluation and grading
Mid-term study requirements
The mid-term mark is based on the successful completion of the two written test during the semester, the successful participation in each of the laboratory practices and the timely submission of the laboratory protocols. In case of insufficient test, replacement is possible one time. The duration of the written test is 45 minutes. The mid-term mark is determined on the basis of the average of the % results of the written test, but a student who did not participate in any of the laboratories cannot receive a valid mid-term mark. In addition to the description of the theoretical background, the laboratory report must contain a description of the measurement and an explanation of the measured results. The mid-term mark is based on the successful completion of the two written test during the semester. The mid-term mark is determined on the basis of the average of the % results of the tests, but a student who did not participate in any of the laboratories cannot receive a valid mid-term mark.
Exam requirements
Generative AI usage
1st position: The use of GAI tools is not permitted when solving tasks. This means that GAI tools cannot be used when creating or solving formative or summative assessment elements, and the use of generative AI constitutes academic misconduct. The use of AI tools for language and spelling checking is not subject to the complete ban under the 1st position.
