Requirements
A, for a signature:
Attendance on the lectures is recommended, but not compulsory. Participation at practice is compulsory. Student must attend the practices and my not miss more than three practice during the semester. In case a student misses more than three, the subject will not be signed and the student must repeat the course. Student can’t make up a practice with another group. The attendance on practice will be recorded by the practice leader. Being late is counted as an absence. In case of further absences, a medical certificate needs to be presented. Missed practices should be made up for at a later date, to be discussed with the tutor. Students are required to bring the drawing tasks and drawing instruments for the course with them to each practice. Active participation is evaluated by the teacher in every class. If student’s behavior or conduct doesn’t meet therequirements of active participation, the teacher may evaluate their participation as an absence due to the lack of active participation in class.
During the semester there are two tests: the mid-term test is in the 8th week and the end-term test in the 15th week. Students have to sit for the tests.
B, for grade:
The course ends with exam grade. Based on the average of the test results x 0.3 + the exam grade from the theory x 076 the mid-semester grade is calculated as an average of them:
The minimum requirement for the mid-term, end-term tests and for the exam is 50%. Based on the score of the tests separately, the grade for the tests is given according to the following table:
Score / Grade
0-50 = fail (1); 51-60 = pass (2); 61-74 = satisfactory (3); 75-89 = good (4); 90-100 = excellent (5);
