Classification of the work during the semester:

• The work at seminars within semester is classified by 40 points.
• 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.
• Active participation at seminars is classified by 10 points. A point is deducted for each unexcused 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.
• 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. If you have more than 80% attendance at seminars (i.e. maximum 2 seminars are missed), the minimum amount of earned points during the semester to obtain the assessment is 10.
• It is not possible to pass the exam without the assessment.
