Mathematics is actually a relatively dead thing, junior high school mathematics is formulaic, you want you to clear the understanding of the conditions given by the question, choose the corresponding formula, the correct answer is actually not far from you.
You've done a lot of exercises, but have you ever gone back in time to see if you really understood them?
I suggest that you sit on 10 questions over and over again until you really understand them, and then expand your thinking about the same type of questions, so that you will improve.

Individuals have a state of learning, continue to maintain the perseverance that you try to break this state, and then it is to do more problems and find methods and patterns. My chemistry is like this, I never got started from living in school to my sophomore year of high school, but then by chance, the whole idea was clear, and it was important to persevere! Come on!
-
You must understand that primary school mathematics and middle school mathematics are completely different things, in middle school, you must pay attention to the efficiency of listening to the class, only after you understand the class, do the corresponding exercises, consolidate them, mark them in the place of the problem, ask the teacher and classmates in time, and insist on practicing mathematics every day to cultivate an interest in mathematics.

Friends, learning mathematics interest is very important, junior high school mathematics is very simple, divided into geometry and arithmetic, of which arithmetic is a little difficult, the difficult is functions, and equations, don't do the problem alone, so it's useless, to find a way to solve the problem from the problem, accompany the interest in mathematics, I wish you progress in learning!

Hehe, my math turned out to be a shortcoming, based on my experience.
1.Follow the teacher, after all, the teacher has been teaching for n years, and many methods and skills are very practical 2Do the questions appropriately, don't be greedy, but you must do it, find some questions to practice after learning the concept and method, you must do it independently, carefully evaluate and correct it after doing it, find problems, and solve them.
3.As for the application questions you said, maybe your mathematical model building ability and analysis ability are still relatively lacking, there is no shortcut to this, you can only practice more, it is recommended to find a good teaching aid, answer analysis should be comprehensive, look at the example questions, learn to analyze the type of problem, extract data, and establish a model.
Try your best, and you'll soon discover the joy of math

I think:
First of all, it is necessary to listen carefully to the lectures, which is a must, needless to say.
Again, if you don't know how to ask, you can't say that it should be, and in a statement like this, mathematics should be rigorous!
Also, it is necessary to do more.
Hmmm... Also, it's better to buy a reference book, not much, as long as there is a detailed analysis;
It's best to preview it, if you don't understand it, it doesn't matter, just stare at the problem in class, listen to the teacher's explanation, and generally understand...
If you don't learn well, it's okay, take a deep breath and watch. Good luck.

The premise is that you use people to teach the textbook.
Endorsement (all the blue characters are memorized, and the rest can be looked at casually.) Then it's the question in the composition book (there must be an answer).
It is recommended to use the 5-year high school entrance examination and 3-year simulation (there is a blue book in the middle.,There are answers to the textbook.,It's not necessary to use the textbook.。。 )
Then do the question, which one to do? First make a book called what gold medal each lesson pass (the small book is very simple. And then go and do the Consolidated Edition of the Top-Notch Foundation.
After finishing it, I went back to make a big book for each gold medal lesson.
I did 5 years of high school entrance examination and 3 years of simulation.
Finally, make a gold medal for each subject of the volume.
Then you can also choose to do the start-up math workbook.
==Gorgeous Split **********==== Finally, use a book called the full docking of the high school entrance examination Olympiad.
You can also try the Olympiad tutorial.
A segment is divided into a horizontal increase.
The choice is yours. The third part can not be (Olympiad).
Finally, it is necessary for the high school entrance examination. . .
I wish you a speedy success.
How difficult it is... Give the best...

Listen well in class. Do more questions. Take a look at the old questions from the past. Take out the questions you did wrong in the past and don't be afraid of trouble.
Don't look at the background of the application question, just treat it as an ordinary question.
You should be able to start doing it. That book. The latter ones may be taught in the third year of junior high school.

Understand the concept theorem clearly and prove it logically.

Try to study on your own, get some basic questions, the teacher has to take care of the whole class in class, the class speed is relatively slow, if you don't understand, don't listen to it, take out the textbooks for three years, start from scratch, take out the previous reference books, and borrow them from classmates if you lose them, it will be a little difficult at the beginning, and it will be okay slowly, I hope it will help you, good Nuriha!!

Equations and what is important for the preparatory course.
Two words, come on, four words, come on and work hard, I just graduated from junior high school this year, understand your feelings, just like I don't know anything in high school, so that the heads of those questions are big, and they are all good students in the competition, now you have to adjust your mentality, I often think that when I was just in the first year of junior high school, I felt that everything was difficult to die, and after the high school entrance examination, I felt that these questions were simple and simple, and I think you will have this mood after the high school entrance examination. Of course, it is the most important thing for you to lay a good mathematical foundation in the first and second years of junior high school, rest assured, don't be afraid, in fact, those questions in the high school entrance examination are simple, and we were also stunned by the teacher at that time, and we were not scared lightly, as for the one-dimensional quadratic equation, small case, to give you an example, it doesn't have three methods, with the method, the formula method, the cross multiplication method, you just need to memorize the formula, what problems are solved, as for the matching method to teach you a trick, such as the square of x - 13x+25 4=0, divide the coefficient in front of the second term by two, i.e., the square of (x-13 2), and then according to the perfect square formula, i.e., the square of (x-13 2) - the square of (13 2) + 25 4 = 0
x-13 2) squared -144 4 = 0i.e. (x-13 2) squared = 144 4, i.e. x-13 2 = 12 2, i.e. = 6
x1=13/2+6
x2=13/2-6

I hope I can help you, please be satisfied, I'm tired to death...

Well, mathematics is definitely a subject of brushing questions, of course, if your IQ is quite high, you don't have to think about it, but at the same time, classroom efficiency is quite important, simple may be that you only see the surface of a question, without in-depth research, if you change the angle of the question, it may be difficult for you, attitude, is also very important.
-
Anyway, it's just to do it, and if you do it wrong, you can find the same type of work, you know, mathematics, this kind of thing likes to be done.

In any case, the teacher's lecture still has to be listened to, it is the most basic, in terms of doing problems, it is necessary to practice difficult problems, but you can't just do difficult problems, basic questions should also be done, in general, in fact, I don't think you need to do too much, do it and forget, but to do a question, you have to understand it thoroughly, the next time you encounter something similar, it will be no problem, remember the foundation is very important.

Listen carefully in class, try not to do without taking notes, listen to the teacher's analysis in class, and then do exercises after class. Ask the teacher more questions that you don't know.
Let me tell you. It's better to choose science.
The reasons are as follows1. Science seems difficult, but in fact, it is easy to catch up, and the method is appropriate and effective. Find a good teacher or one or two top math students, communicate more, practice more, and get a perfect score in math. >>>More
The foundation of high school has little connection with elementary school and junior high school, and it can be made up. >>>More
First of all, let me tell me, I am Henan, and I am now studying in Shanghai. When I was a freshman in high school, I played it completely, and I didn't pass the math, and at that time I couldn't even understand functions, and I couldn't do basic operations like sin and cos. High 2 starts to get angry, math you have to eat the book thoroughly! >>>More
Try to be as independent as possible, don't ask if you can ask people, you don't have to do more questions, but the concepts must be understood, and you may as well try to deduce the formulas in the book yourself. Of course, everyone's situation is different, the key is to think more about it when you study and see which method is suitable for you.
You don't have to attend any training courses, and you spend money in vain. Science: Physics, Chemistry, Biomathematics. Chemistry is the easiest, known as the liberal arts in science, as long as you memorize more, you can get a high score; Creatures are basically backrests as well. >>>More
