The university students want to learn the most useful subjects for themselves through their　university periods. But the students in most universities are forced by the authorities to take　a lot of required subjects. 80 students can't make good choices by their wills，in spite of a wide presentation of elective　subjects. In this paper we present the advantages of a curriculum on our department that　increases the freedom of subjects. We pick out public qualifying examinations this time，and propose curriculum corresponding　to the examinations.
