"Even though the students are enrolled into their respective faculties, they may still choose a lecture from another faculty. The lectures are divided into three categories, A (obligatory), which a student of a given field has to pass; B (facultatory), certain number of which a student has to pass in order to collect enough ECTS-credits; and C (facultatory) which a student may choose to appeal his interest in a different field. Therefore it is possible, for example, for a Law Faculty graduate to have strong knowledge of Biochemistry, if he decides for the C lectures of Faculty of Science."
