From a technical point of view, you said that everyone basically failed. From the analysis of this sentence, the topic is difficult to write, but there are also high and low scores for passing. The difference between 89 points and 60 points is nearly 30 points. You should analyze it yourself. Although I worked hard, I did so badly in the exam every time, or did I fail occasionally this time? There are many courses in high school, and the courses are complicated, so we need to master the skills and tricks in learning, and we can't do them foolishly. Although students are skilled workers, they sometimes need skilled workers. There are many math problems, many difficulties and tight time. However, everything can't be changed without it. As long as one method is mastered, it is possible to solve several problems. So my suggestion is that you usually use a big notebook to record some wrong questions, and what are the key points and difficulties of such questions are marked in the notebook. Mathematics really tests a person's analytical ability and independent thinking ability, but what should we do when we come to a dead end? It's simple. We need the teacher's advice. A word from the teacher will make us loyal wives and will be remembered by you. This is the learning method.

Classmate, you are only a sophomore. You have time. Study hard! ! There will be a good result! !
