This shows that there is something wrong with your attitude towards learning mathematics. Strategically you are valued, tactically you are despised. Usually, I often find mathematics difficult, but if I know a little, I feel very simple or understand 1, but I don't really understand it. I suggest you use questions to test what you don't understand, write it down and attend classes with questions, which may be much better. Of course, don't do it when you get the problem. My personal experience is to do the example first, then look at the answer, and then compare it with the answer, because the example is classic but not difficult, and it is a good question bank. Finally, I suggest you ask more questions when you don't understand-this is the best way to learn math. I can become a top student in mathematics in the college entrance examination, relying on a solid foundation, reading many examples, and asking if I don't understand. Of course, targeted exercises are also important. Having said that, I hope you understand. Come on! I believe you can do it.
