Mid-term study requirements:
During the semester, we check the acquired level of knowledge by writing 2 pieces of 50-50 points written examination papers. If the scores of the booth examinations do not reach 50% of the maximum available score (minimum 25-25 points), we will give opportunity to write an 100-point extra written examination paper. Conditions for admission to the exam: At least 50% of the written examinations (at least 25-25 points) or the extra written examination must be at least 50 points. Examination requirements: The exam consists of a written and an oral part. At the request of the student, we accept the written examination papers result as the written part of the exam. In the oral exam, a ticket can be corrected compared to the written result. In the oral examination, at least a sufficient level of knowledge of all major parts of the material is required to obtain a successful exam grade
