Requirements for granting the credit and exam Conditions for granting the credit: - participation in exercises (20% of absences can be excused), -submission of credit work in the required quality. The student receives 5 points for attendance and submission of credit work. Additional points (0 to 30) can be obtained by elaborating homework in the given term. In total, it is possible to get a maximum of 35 points. The minimum number of points for credit is 5. Exam: Combined Practical part max. 55 points. Theoretical part max. 10 points. Total max. 65 points. Students must pass in each part of the combined exam: In the practical part they must obtain at least 25 points, in the theoretical part at least 5 points. Score is obtained by adding points from exercises (max. 35) and exam (max. 65) and graded: Earned points Score 86 - 100 excellent 66 - 85 very well 51 - 65 well 0 - 50 failed
