# Grading Regulations:

• The test for 50 points. The test covers the first part of the material. There is no possibility to retake the test.
• The exam for 50 points. The exam covers the second part of the material. If someone did not write the test, then the exam covers the whole material from the lecture and is graded for 100 points.
• In the second term the exam covers the whole material from the lecture and is graded for 100 points.
• The grade (on the basis of the sum of the test and the exam or only the exam) by the conversion table:  POINTS GRADE < 50 2 from 50 3 from 60 3.5 from 70 4 from 80 4.5 from 90 5
• Cheating on tests and exams will not be tolerated. If a student get caught cheating, the test/exam will be confiscated and rated to zero points.
