Simple. Tongji University stipulates that those who pass the course and reach the passing line (excluding converted scores) of the course examination or examination results of the current year can apply for a second interview, and will not participate in any teaching activities during the hearing exemption period, but they must complete the homework, experiments, examinations and other links of the course as required. If the homework, experiments, exams and other links of the course are completed during the period of no hearing, and the scores reach the passing line, then the credits and scores of this course will be included in the student's student status file, and the scores will not be included in the grade point calculation. If students finish the homework, experiments, exams and other links of the course seriously during the period of no listening, and their grades reach the passing line, then they can pass the course smoothly, which has no influence on the students' grade points.
