Junior high school mathematics, don't need how to practice, full marks 120, 1 10 need to practice more, and it's almost enough to get a hundred points. Many people have a misconception that doing problems is useful, but you are not suitable. Doing problems is only suitable for a certain level. At this time, you can check your learning results by doing the questions, but according to your description, you may not have mastered the basic knowledge, so it is of little significance for you to do the questions. Objectively speaking, the cost performance is very low. That's how I got here. I know these things better. I have a part manager myself. The questions in the senior high school entrance examination and the college entrance examination are very hierarchical. Generally speaking, as long as you understand this basic concept and have normal intelligence, most of them can be worked out. And the rest will test your personal math ability. In other words, you don't have to practice the questions, but you can get at least 70% or 80% if you understand the basic knowledge points. Then practice the topic a little and look for experience. It is quite easy to get more than one year 100 points for the knowledge of grade three. But the point is that you should understand, memorize formulas and think more. As long as you understand that doing a problem is better than 100, in fact, you want to assume that a chapter consists of 10 knowledge points, and you practice 100 against the problem, then an average knowledge point will appear 10, but why are some people still wrong, because they only see this specific problem and don't pay attention to it? I once gave an example in high school. A classmate wanted to brush the questions, but he did it wrong. Sometimes he makes the teacher understand, saying that the teacher should do this, asking him why, and explaining together. At this time, you find that many of his basic concepts are wrong, so it is not for nothing to do so much. After going to college, there are no questions to do in many classes and no exercise books. Sometimes there is no homework in one semester, and people can't get full marks. How do they study, read, look up information and think? Under the educational system of China, the theory of sea of people tactics came into being. But the essence of doing problems is actually to help you understand knowledge, and doing problems is not an end in itself. I suggest you learn the basic knowledge well first, and then you can practice the questions properly, but not too much. Talk about quality when doing problems. You know a question better than doing 10, so I think the school has issued enough questions. Personal opinion only. In addition, there is another lesson to learn in high school. The biggest gap in a good high school is not the quality of teaching, but the learning atmosphere. This is very important. The most important thing for senior one to senior two is to develop study habits and thinking habits. When doing problems, I often ask myself why I want to do this. If after you write a question, there is still something you can't explain, then the concept is not fully grasped. Ask the teacher at this time. Don't ask him how to do this problem, ask him what you think of this problem, what doubts you have and how to deal with it. If you don't understand the answer, ask why you did it. Besides, be confident. Now you think you should study hard, which proves that you have made progress. Believe me, learning is always right. And don't look at the classmates around you. Others don't work hard, they just don't understand. If you work hard one day, you will be very happy.
