In the final analysis, science still depends on doing more problems and summing up more problems. As for the problem, we must first consolidate the basic knowledge, so that we can study it in depth. It is not difficult to do more problems and communicate with classmates and teachers to improve a lot of mathematics, but it is theoretical and complicated and needs logical reasoning. But don't be afraid of math, and don't be too nervous. Just keep your grades open, or you will be too nervous to review. If you are nervous, you will be afraid. Mathematics is not difficult, so don't be nervous. Improve your grades. Learning problems. There are learning links, learning attitudes and learning methods. As long as you change your study from now on and study hard, it will be easy and your grades will improve. Everyone has a different foundation and attitude towards learning, so the methods to be adopted are different. If you want to learn well, you must find a suitable learning method and choose a suitable method according to your own characteristics. You can make progress. The method of learning should be "a hundred schools of thought contend" and "a hundred flowers blossom". Starting from the basics-familiar with skills-application. I must have practiced it countless times. Understand the characteristics of the subject, recite formulas, think more, dig more, and do more problems. There is never a shortcut to learning, only practice, practice and practice again. Provide the following methods: Do four rounds of study well: 1. Review the basic knowledge comprehensively (see the textbook). 2. Use the exam to test your first round of review. Analyze the existing problems in detail, and do a good job of checking and filling the gaps. 3. Review section by section. To achieve similarities and differences, differences and similarities. 4. Special review. Cultivate comprehensive ability and expand their application ability. Follow-up: But whenever I encounter a problem I don't understand, I give up and never try to solve it. Sometimes I want to copy my classmates' answers. Do you have to practice if you want to improve your grades? I am a little lazy to answer: practice is a necessary question. If you can't do it, you should ask your classmates how to do it. If you plagiarize, it will be a vicious circle. You won't do this kind of problem again.
