ECTS: 5.0
Lecturers in charge: prof. dr. sc. Zlatko Mihaljević
Lecturers: Valentina Dorić , mag. biol. exp. - Practicum
Take exam: Studomat
English level:


All teaching activities will be held in Croatian. However, foreign students in mixed groups will have the opportunity to attend additional office hours with the lecturer and teaching assistants in English to help master the course materials. Additionally, the lecturer will refer foreign students to the corresponding literature in English, as well as give them the possibility of taking the associated exams in English.
