Course completion requirements -

To obtain the course credit, it is necessary to earn at least 120 points out of a total of 240 points awarded throughout the semester.

Students who have earned at least 100 points by the end of the course may make up the remaining points by completing additional homework assignments or taking an extra written test (according to the instructor's instructions).

In justified cases (long-term illness, stay abroad, etc.), the instructor may set individual conditions for awarding the credit.

The course credit ("zápočet") is a prerequisite for taking the exam.

Any kind of cheating constitutes grounds for withholding the course credit.

Requirements to the exam -

The exam requirements correspond to the syllabus of the course in the scope covered during lectures, exercises, and assigned self-study. The ability to apply the acquired knowledge when solving problems is also required.

The exam typically consists of a written and an oral part.

The course credit ("zápočet") is a prerequisite for taking the exam.

The results of tests taken during the course may be considered during the exam.
