Prerequisites - other information about course preconditions |
Wider general knowledge in the fields of physical chemistry, organic chemistry and technology, polymer chemistry and chemical engineering. |
Competences acquired |
The examination is oral. The basic form of the test is the debate over selected thematic headings. The degree of knowledge acquired and the ability to combine knowledge acquired in the subject into the broader context of the field studied is examined. |
