Classification of the work during the semester:

• Attendance at all seminars is mandatory and active participation, knowledge of problems presented at preceeding lectures, and mainly the knowledge of problems solved at previous seminars are required.
• The work at seminars within semester is classified by 40 points in the following structure:
  • Active participation at seminars is classified by 10 points. A point is deducted for each unappologized absence and also for significant passivity at the seminar.
  • An absence can be appologized in the case of approved illness or a serious personal reasons (in this case the absence must be appologized in advance).
  • 30 points can be obtained on the basis of 4 short tests (the date are annonced within the schedule of minars. Test can be written in other date only exceptionally and from very serious reasons only.
  • The decision to excuse an absence or deduct a point is at the discretion of the teacher.
  • Student can obtain some bonus points in the case of exceptional activity at seminar.
• Mandatory condition for the assessment is the earnings of minimum 20 points during the semester, i.e. 50% of maximum points from seminars.
• It is not possible to pass the exam without the assessment.
