Assessment Methods and Criteria (valid 01.08.2018-31.07.2020): 

Lectures, exercises and group work.

Elaboration of the evaluation criteria and methods, and acquainting students with the evaluation (applies in this implementation): 

Grading is based on exercise problems and group work. There is no exam.

Exercise problems: 60 p (five rounds, 12 p / round)

Group work: 35 + 5 p

  • 35 p: presentation and report
    The points awarded depend on the grade of the report:
    Excellent: 32–35 p
    Very good: 28–31 p
    Good: 24–27 p
    Very satisfactory: 20 - 23 p
    Satisfactory 16 - 19 p
  • 5p: Evaluate at least two reports by other groups (mandatory)

Total: 100 p

Bonus points:

  • Evaluate additional group work reports (1 p / report past the first two)
  • Course feedback (1 p)

The points are converted to final grades according to the following table:

Excellent (5):         82.00 to 100.00 points
Very good (4): 74.00 to 81.99...
Good (3): 66.00 to 73.99...
Very satisfactory (2): 58.00 to 65.99...
Satisfactory (1): 50.00 to 57.99...

Explanation for the point grade limits:

  • For passing the course (1), you need to get one half of the maximum points (50 p).
  • A grade of Excellent (5) can be obtained, for instance, by getting an Excellent grade from the exercises
    (> 48 p), a Very Good grade from the group work (> 29 p), and
    evaluation of two group work reports (5 p). 48 p + 29 p + 5 p = 82 p.
