II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via tests, homework assignments and class work.
3.2 Assessment methods
Evaluation form Abbreviation Assessed learning outcomes
Midterm control test #1 ED1 A.1-A.4; B.1; C.2, C.5-C.7; D.2, D.4
Midterm control test #2 ED2 A.4-A.6; C.2, C.5-C.7; D.2, D.4

The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
3.3 Evaluation system
Abbreviation Score
ED1 25%
ED2 25%
HF1 10%
HF2 30%
A 10%
Total in semester 100%
Sum 100%
3.4 Requirements and validity of signature
No signature can be obtained.
3.5 Grading system
To obtain successful grade, attendance requirement must be fulfilled.
Semester grade is failed, if any of the following applies:
  • ED1 is failed if the gained points do not achieve 50% of the achievable points.
  • ED2 is failed if the gained points do not achieve 50% of the achievable points.
  • Homework is failed if the sum of the homework and consultation points HF1 + HF2 does not reach 50% of the achievable points.
Each student has consultation record sheet for the homeworks. The supervisor evaluates each student separately during consultations. Malus points can be also obtained for consultation. Homeworks are also graded (in case of group work parts, all member of the group will obtain the same points), which is added to the consultation points
The final grade is computed on the basis of the sum of ED1 + ED2 + HF1 + HF2 + A, as follows:
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%
3.6 Retake and repeat
  1. Each ED can be repeated (2nd attempt) during the last week of the study period of the semester.
  2. ONE of the two EDs on request can be also repeated during the supplementary week (3rd attempt) (penalty fee applies).
  3. Late submission of HF1 is possible one week after the original deadline electronically via the website of the subject. (penalty fee applies)
  4. Late submission of HF2 is possible on the last day of the supplementary week by 12:00, electronically via the website of the subject. (penalty fee applies)
  5. “Active involvement in lectures” A cannot be repeated, cannot be substituted with other forms of activity.
