Successfully passed exam. During the term, students complete usually three partial tests, which are required to be passed successfully and their results are taken into account in the examination. Individual projects are not compulsory, but students can receive a bonus rating. The exam is in the form of a final test, which can be completed with the oral part of exam by a discussion on particular questions. Last update: Cejpek Karel (08.05.2018)
