Graduation study, according to a course, is the last link of general secondary specialized schools, junior colleges, undergraduate colleges, higher education self-study examination undergraduate and postgraduate professional education. In order to enable students of this major to concentrate on scientific research and training, students are required to summarize and write papers independently before graduation.
