The main thing is to learn quadratic functions well.

1. Preview before class. If we want to learn mathematics well in the third year of junior high school, we must set aside enough time before learning a new lesson, preview the new content, and mark the places that we will not know.
2. Listen carefully in class. If we want to learn mathematics well in the third year of junior high school, we will be able to listen to the lecture in a focused way when we take this class, and we must listen carefully when listening to the teacher's lecture.
3. Complete homework carefully after class. If we want to learn mathematics well in the third year of junior high school, after we have learned new knowledge, the teacher will assign homework, and we must complete the homework carefully after class to consolidate the knowledge.
4. Be good at summarizing and organizing. If we want to learn mathematics well in the third year of junior high school, we must be good at summarizing and sorting out the key content after we learn it, and constantly strengthen and memorize the key knowledge.
5. If you don't understand, you have to ask. If we want to learn mathematics well in the third year of junior high school, if we bump into the knowledge points that we don't know, we must ask the teacher or classmates in time, and if we don't understand, we must ask.

When you mention a concept or nature, you already have a blueprint in mind and can say it in your own words. In fact, when you understand it, you will naturally be able to react, which is very different from the comprehension and memorization of the liberal arts
Again, it's not about blindly brushing questions. Moreover, there is a goal and intention to do the questions, and high-level students only need to practice appropriately. As far as the test is concerned, the focus is on the problem-solving ideas, problem-solving methods, and problem-solving strategies, which need to be summarized and refined.
After understanding this, I suggest that you can classify, divide topics, and sub-question types to make breakthroughs, self-summary, which can be problem-solving routines, but don't forget to try to think about what is the essence behind the thinking routine.

Listen carefully in class and practice more after class.
Mathematics: Theorems in textbooks, you can try to reason on your own. This will not only improve your proof ability, but also deepen your understanding of the formula.
There are also a lot of practice questions. Basically, after each class, you have to do the questions of the after-class exercises (excluding the teacher's homework). The improvement of mathematics scores and the mastery of mathematical methods are inseparable from the good study habits of students, so good mathematics learning habits include:
Listening, reading, **, homework Listening: should grasp the main contradictions and problems in the lecture, think synchronously with the teacher's explanation as much as possible when listening to the lecture, and take notes if necessary After each class, you should think deeply about it and summarize it, so that you can get one lesson and one lesson Reading: When reading, you should carefully scrutinize, understand and understand every concept, theorem and law, and learn together with similar reference books for example problems, learn from others, increase knowledge, and develop thinking **:
To learn to think, after the problem is solved, then explore some new methods, learn to think about the problem from different angles, and even change the conditions or conclusions to find new problems, after a period of study, you should sort out your own ideas to form your own thinking rules Homework: to review first and then homework, think first and then start writing, do a class of questions to understand a large piece, homework to be serious, writing to standardize, only in this way down-to-earth, step by step, in order to learn mathematics well In short, in the process of learning mathematics, It is necessary to realize the importance of mathematics, give full play to one's subjective initiative, pay attention to small details, develop good mathematics learning habits, and then cultivate the ability to think, analyze and solve problems, and finally learn mathematics well
In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method. Good luck with your studies!

Focus on the basics, remember the concepts, just follow the pace of the teacher, listen carefully in class, actively complete homework after class, make up for your weaknesses in time, and do more questions. There is nothing difficult about junior high school math, so listen to it.

The methods and skills for learning junior high school mathematics well are as follows:
1. Prepare carefully before class.
The purpose of the preview is to be able to better listen to the teacher's lectures, and through the preview, the mastery should reach 80%. Listen to the teacher's lecture with questions that you don't understand in the preview to answer these kinds of questions. Preview can also improve the overall efficiency of the lecture.
Specific preparation method: Complete the questions in the book and draw the knowledge points, and the whole process lasts about 15-20 minutes. If time permits, you can also finish the workbook.
2. Combine learning and practice in mathematics classes.
In math class, it's useless to just listen. When the teacher asks the students to go to the blackboard to perform calculations, they also have to practice on scratch paper. If you encounter a problem that you don't understand, you must put it forward, and you can't help but seek a solution.
Otherwise, you may not do it if you encounter similar questions in the exam. When listening to the teacher's lecture, you must pay full attention and pay attention to the details, otherwise the embankment of thousands of miles will be destroyed in the anthill.
3. Review in time after class.
After writing the homework, you can sort out the content of the teacher's lecture that day, and you can do about 25 minutes of extracurricular questions appropriately. You can choose the extracurricular book that suits you according to your own needs, and the content of the extracurricular questions is probably today's class.
This is to detect recent learning. In fact, the score represents the past, and the key is to summarize and learn lessons from each exam, in order to do better in the mid-term and final exams.

Good math methods and skills in junior high school:
1. Pay attention to the foundation and review the textbooks frequently
In the high school entrance examination, the basic knowledge test accounts for nearly 60%, and at the same time, the textbook is the source of all our questions. Therefore, strengthen the study of basic knowledge and lay a solid foundation. Review the textbook frequently and familiarize yourself with the process of each knowledge point.
To achieve the foundation of building a basic knowledge tree, to be familiar with the title frame diagram on the textbook.
2. Pay attention to summarizing and mastering methods
At the same time, you should often supplement your mathematical thinking methods and methods, and ask more questions to the teacher.
3. Be diligent in practice and do more questions in the middle school exam
Mathematics is different from other liberal arts subjects, and you can use it if you memorize it, but mathematics is a subject that requires a strong sense of logic, and you must practice it regularly after mastering the basic knowledge points.
The sail qiao workbook issued by the school must be proficient in answering every question, and at the same time, often do some high school exam questions, see the rules of the middle school exam questions, and grasp the trend of the proposition.
On the premise of remembering the formula clearly, do the questions appropriately, don't blindly do a lot of question types, and then don't remember the last one, in fact, this is a waste of time, and then the grades have not improved.
As long as you master a type of question, it will be easy to encounter the same type of questions in the future, so don't blindly pursue more.
