All universities usually have both faculties and departments. The faculties are arts, law, medicine, science and theology. The departments include engineering, economics, commerce, agriculture, music and technology. At the head of each faculty there is a professor. A staff of teachers called lecturers helps him. Professors and lecturers give lectures to large numbers of students or study with small groups, and here the students have a chance to discuss.
