From junior high school to senior high school, there will indeed be a period of inadaptability. The advice to the landlord is not to get into trouble all the time. After learning a chapter, think about what knowledge points this chapter mainly talks about, and then when doing after-school questions, clearly distinguish which knowledge points each question is taking in this chapter. It seems that the landlord is entangled in science. First of all, there are several points to be determined. Do you understand everything the teacher said in class? Did you do all the exercises after class? Landlord, you are struggling because you are not confident, and you don't believe that you can solve all the problems. As an experienced person, my advice to you is that science study is a general thing. As long as it is mastered in the general direction, several specific special situations can be mastered through continuous practice. If you struggle next time, push the formula down. The application of painting in science is very important. Images can give you a more direct feeling.
