Criteria for obtaining of kl.z. (classified assessment):

C1. Attendance is mandatory (apologies only in case of serious documented reasons).

C2. Student has to be prepared on the exercise according to documents prepared for the laboratory experiments and by lecturers (see below description of the test).

C3. Over the semester, it is possible to get 100 points. Conversion to evaluation (A, B, C, D, E, F) will be held according to the ECTS grading scale listed in the study and examination regulations of CTU.

C4. Points can be obtained for the successful completion test at the beginning of each exercise (a total of 4 tests), for participation and one written protocol for the selected task. Processed protocol 26 points (max. 26 pts, min. 8 pts), with the participation of 10 points and 16 points test (test 4 times, i.e. 64 pts max. and 32 pts min..) In total, min. 50 points - E, up 100 points - A.

C5. The test consists of 4 questions each for 6 points (max. 26 points, min. 8 points, i.e. 4x2). All questions are based on the previous content and related lectures and laboratory preparation topics.
