I don't want to enter the top class.

That's not true. Around me, the top class is the fairest class. I have never seen anyone go through the back door, but there are many ordinary classes going through the back door, because the school should ensure that the key rate of top classes is 99%- 100%. The teachers in the top class don't pay attention to the basics, but they do. Maybe you don't pay attention to them because the teacher thinks that everyone's foundation is well learned, and there will be problems (if not, you can ask the teacher more questions and the teacher will realize it). Moreover, I think everyone in the top class has the possibility of 1, which is generally a turn, unlike the ordinary class where one or two people are the first, which will cause the teacher's eccentricity. Besides, teachers will not give up every student easily. In the top class, it is important to be positive, because everyone is not worse than others and has strength.
