| Sum | 100% (109% achievable with bonus points) |
20 points can be reached in each midterm test, to pass the tests (and obtain the signature) minimum 50% should be reached separately on each test (min 10 points from each test). Two midterm tests can be repeated during the retake period.
Homework assignments worth 3 (bonus) points each, for a total of 9 (bonus) points, the homework are not compulsory. No points will be awarded for homeworks submitted after the deadline.
Any student who takes a regular (non-examination) course with a signature received in a previous semester will have his/her previous result overwritten by his/her result for the current semester. Mid-semester results obtained previously in the subject and taken into account for the determination of the examination grade may be accepted retroactively back to 6 semesters.
| Grade | Points (P) |
| excellent (5) | 85%<=P |
| good (4) | 75<=P<85% |
| satisfactory (3) | 60<=P<75% |
| passed (2) | 50<=P<60% |
| failed (1) | P<50% |
Final grade is determined on the basis of the sum of the points obtained during the semester and the exam. For successfully pass the subject beside the signature min. 40% (24 points) should be obtained during the exam.
One midterm test can be repeated during the retake period.
