Conditions of credit:

Obligatory and active attendance at all tutorials. Absences are acceptable for serious reasons only and must be apologized and recompensed. Student has to come in time. For each lab session working out a report in corresponding quality. For the attendance at each lab session student has to pass an entrance test at least for 60 %. In the other way, he has to recompense the session with the test on an other date. An entrance test could contain the topics from the actual lecture and from the base and instructions for the labo session.

Grading tests (including calculation) at least for 50% (in sum from tests).

Examination conditions: Student has to pass a written test comprising the topics discussed during the lectures and tutorials, including assigned individual study. The exam is graded according to the ECTS scale, to pass the exam, the test must be evaluated at least at 50 %.
