"May 3rd" or other advanced materials are the same, which must be useful for improving the results of the college entrance examination. The degree of usefulness is different, depending on the talent of candidates and the level of teachers. If students are highly talented and teachers are highly qualified, but there are no teaching AIDS, the results of the college entrance examination will also be greatly affected. If students' talent and teachers' level are poor, it is impossible to achieve good results even with the best teaching materials, let alone without the best teaching materials. There are many advanced materials at present, and none of them is the best. That makes no difference. Whether it is good or not depends entirely on the level of the teacher. High-level teachers don't have bad advanced materials, and low-level teachers don't have good advanced materials. Excellent performance in college entrance examination is an organic combination of students' talent, hard work and teachers' level. Without any of them, there will be no good result.
