Need to reply. The main links of correspondence teaching include self-study, face-to-face teaching, homework, answering questions, experiment, practice, assessment, graduation design and defense.

Students must submit their graduation thesis in triplicate, together with the outline and draft, half a month before the thesis defense meeting, which has been approved and signed by the tutor. The main defense teacher of the defense Committee will draw up the questions to be asked on the basis of carefully studying the graduation thesis, and then hold a defense meeting. At the defense meeting, let students spend about 15 minutes to summarize the topic and the reasons for choosing the topic, and introduce the main arguments, arguments and writing experience of the paper in detail. Then the main defense teacher can ask questions.
