Assessment: Attendance at lectures: The rules of education and exam directory (TVSZ) are the guidelines. Exams and tests (types, data) Test #1 (week #6), Test #2(week #13). Requirements for qualification: Signature can be obtained if the sum of the points obtained in the two test is at least 40 % of the total of points. In the opposite case a supplementary test from the material of the two tests on week #14, and (if required) one more possibility at the beginning of the exam session, with similar percents. Type of exam (written, oral, tests etc.) and the method of assessment: Written exam from the material of the whole semester for max. 26 pts. Marking: 22-26: excellent (5) 18-21: good (4) 14-17: satisfactory (3) 10-13: pass (2) 0 - 9: fail (1)
