According to the provisions of Article 42 of the Higher Education Law, the credits obtained by students through study and examination can be recognized as compulsory or elective credits for their major or discipline. However, the maximum exemption rate of each student shall not exceed 50% of the total credits of his major and discipline.

Therefore, if the total credit of a major is 120 credits, then students can be exempted from taking courses and taking exams for up to 60 credits. Of course, this does not mean that all schools or majors have this restriction, but it depends on the specific policies and regulations of each institution or major.

Exemption from courses and examinations means that in the academic planning of college students, they have obtained corresponding academic achievements or credits through their previous study and examination experience, which can be recognized as compulsory or elective credits for their major or discipline.

Therefore, the process of further education and examination can be exempted. The mechanism of exemption from courses and exams is a very important policy in the field of higher education, and its purpose is to promote students' in-depth study and enhance their professional ability.

The mechanism of exemption from courses and exams has been widespread in foreign university education systems, and has been well received by students, parents and society. In China, with the popularization of higher education, colleges and universities at all levels have gradually implemented the mechanism of exemption from exams and courses, providing students with more flexible and diverse learning methods.

So that students can better play their own advantages and specialties and achieve their learning goals faster. Generally speaking, college students need to meet certain conditions and standards when applying for exemption. For example, good results have been achieved in the evaluation of equivalent academic ability, subject competition and professional skill evaluation.

According to students' previous academic achievements and credits, for courses with duplicate or similar contents, the school can complete these credits or course requirements directly through courses or exams without taking courses. This can not only effectively reduce students' learning pressure, but also avoid wasting time and resources.

Of course, the implementation of the maintenance-free and inspection-free mechanism also needs certain supervision and restraint. Because students can directly complete the study of related courses through the credits they have obtained without taking courses and exams, it is necessary for the school to establish a perfect course quality guarantee mechanism to ensure that students can truly master this part of knowledge and skills in the process of courses and exams.

At the same time, in the process of implementing the exemption from examination and repair, the education department also needs to strictly perform its education management responsibilities, strengthen the supervision, inspection and evaluation of relevant policies and regulations, and further improve the effectiveness and fairness of the exemption mechanism.

In a word, the mechanism of exemption from examination and repair is a very important policy in the modern higher education system, which has a positive and far-reaching impact on improving the quality of education and teaching and promoting the growth and development of students. Of course, in the process of implementing this policy, all parties need to work together to strengthen supervision and restraint, so that the exemption mechanism can better serve the majority of students.
