Forms of Teaching

Lectures

Course lectures are organized through 2 study cycles. First cycle consists of 7 weeks of lectures and mid-term exam. Second cycle consists of 6 weeks of lectures and final exam. Lectures are held through total of 15 weeks with weekly load of 2 hours.

Exams

Examination is performed in two parts: in eighth week mid-term exam and in fifteenth week the final exam. Exams are written and consist of multiple choice questions, essay questions and exercises.

Exercises
