Universities are places to train talents, but what standards should be used to examine the ability of college students? It is understood that at present, 80% of universities generally implement the credit system to examine the ability of college students. The so-called credit system is an educational system that measures students' academic completion with credits as the unit of measurement. However, can the implementation of the credit system in universities really examine the ability of college students? Is it beneficial or harmful for universities to implement the credit system? Under the current situation, the credit system in colleges and universities does more harm than good. Of course, we have to admit that the credit system does have its advantages, but it is far from covering up its shortcomings. As far as China's current national conditions are concerned, the credit system still has great disadvantages: first of all, the credit system was introduced from the west, and the western countries implemented the course selection system before the credit system, while China has been implementing the academic year system. This change alone makes it difficult for most people in China to adapt to the ideological situation; Secondly, the state advocates teaching students in accordance with their aptitude, and the implementation of the credit system can also allow students to choose their favorite subjects according to their hobbies and specialties. But it is precisely because of this that most students blindly choose subjects, and the hotter the major, the colder it is, and the importance is not important, which makes the quality talents of unpopular majors less and less; At the same time, although 80% universities in China have implemented the credit system at present, most schools do not have the ability to implement the credit system, such as imperfect teaching management system, weak teachers, and lack of a strong attendance system, which greatly increases the difficulty of implementing the credit system in China. In short, the credit system, like a social system, is feasible under the national conditions. At present, China's national conditions do not have the conditions to implement the credit system. Let's work hard in the tortuous development of the credit system in the academic year!
