Reading a book, if you don't understand it once, read it twice, read it three times or four times if you can't read it, and the basic knowledge points are very simple ......Be sure to find a reference book with a detailed solution process, don't buy the kind of book that only has the final result, time is tight, and it is impossible to ponder for a topic for half a day. Do all the exercises in the book, it doesn't matter if you can't, turn the answers, watch the answers to do, close the book when you're done, write silently, and don't look at the answers again until you can write them without thinking. This method seems to be a bit dumb, but the effect on catching up is obvious.
The two most important points: first, you must be attentive, whether it is reading a book or silently. Second, persist and persist.
A word for you: no matter when it starts, don't stop when it starts, and don't regret it when it ends! It's not too late to act!!

In fact, learning is on your own, and there is also junior high school that is only a simple grasp, even if you are a lot behind, it is possible to learn. It depends on what kind of mentality you have, as long as you put your heart into it, there is nothing you can't do, I have also experienced it, junior high school is an attitude problem, study hard. For physics, the important thing is the formula, just remember more formulas and look at a few example problems.
Well, that's all, good luck.
-
Try to see the analysis (the kind that talks about knowledge points) Don't do the above questions first, and do the zero-error questions, you may make a lot of mistakes at the beginning of the zero-error questions, but this is normal, don't be discouraged, the zero-error questions must be understood and read again the next day. Then do the analysis questions.
I wish you success in your studies.
-
First of all, don't panic, seize the time to read the textbook, take the initiative to think about the questions raised in the textbook, especially the homework after class, and then ask if you don't understand. Go back and review more, in fact, physics is not as difficult as you think. Come on!
-
It's still too late to learn, learn the knowledge you didn't understand before, take out the previous books and read them, it's still okay, and then find some practice questions to do.
-
Find PPT from the Internet to study on your own, and then do the questions to practice. If you don't understand, ask your teacher, it should be like this.
-
As long as biology often reads books, review is basically not godless.
-
If you read and understand the basic knowledge repeatedly, and if you don't understand it, ask the teacher immediately, and prepare for it before class, so that it is easy to understand in class.
Junior high school is abbreviated as junior high school. Junior high school is the primary stage of the middle school stage, and the junior high school generally refers to the middle school with nine years of compulsory education, which is a stage of transition to senior high school and belongs to the category of secondary education.
In China, the school year of junior high schools is three-year: seventh grade (first year of junior high school), eighth grade (second year of junior high school), and ninth grade (third year of junior high school).
Primary and secondary assignments
There are many subjects in the curriculum in junior high school, which should be arranged reasonably.
In junior high school education, Chinese, English, History, Ethics and the Rule of Law, Geography, Physics, Chemistry, and Biology are the focus of the study, and in junior high school education, Chinese, English, History, Ethics and the Rule of Law, and Geography are the liberal arts subjects, and mathematics, physics, chemistry, and biology are the science subjects. At the same time, pay attention to the examination of other subjects in the high school entrance examination.

Tell you that as long as IQ is okay, biology can learn very well! Creatures are actually very simple! It's the easiest in science! I don't know how you learn it! Listen to my brother's advice! Read more books! It's better than thinking a thousand times!
-
If you don't understand, just ask the teacher. Or all classmates can do it.

Physics and chemistry in junior high schools in Zhejiang Province are grouped into one subject - science.
The Zhejiang version is only science, science includes physics, chemistry, biology, geography, which is equivalent to the merger of the four disciplines, the content is basically the same as other versions, and the knowledge points of the four disciplines are staggered.
The Zhejiang version of the textbook has a discipline in one chapter and one knowledge point in one chapter. For example, the second unit is the understanding of microscopes and cells in biology, and the third chapter is the knowledge of geography.
Version used in science textbooks in Zhejiang Province:
There are Zhejiang Education Edition (Zhejiang Education Press) and China Normal University Edition (East China Normal University Press). The science textbooks in Ningbo City use the ECNU edition, and the science textbooks in other parts of Zhejiang Province use the Zhejiang Education Edition.
In junior high schools where there are physics, chemistry, and biology classes, biology classes begin in the first year (seventh grade), physics classes begin in the second (eighth grade), and chemistry classes begin in the third (ninth grade). Some of the learning content in the Chemistry and Biology courses overlap with each other. The nutrients in food are not only the learning content of biology, but also the learning content of chemistry.
In the Zhejiang version of junior high school science, there is physics in the first year of junior high school, and chemistry in the second semester of junior high school, such as chemical elements, valence, and chemical formulas. Students can't tell which content in junior high school science is chemistry and what is physics.
Except for Zhejiang Province, I don't know if there are some places where junior high schools do not have physics, chemistry, and biology classes, but there are science classes.

There is no chemistry, and chemistry is a subject set up by the nine-year-old Laxin-level open wheel. The main subjects in the second year of junior high school are: Chinese, Mathematics, English, Geography, History, Politics, Biology and Physics.
The curriculum that runs through the three years of junior high school includes: Chinese, Mathematics, English, Ethics and the Rule of Law. Physics will be taught in the eighth grade, and Chemistry will be taught in the ninth grade.

1.Pay attention. When learning physics, we should first pay attention to observing the physical phenomena given by the teacher and the textbook, such as the questions raised in the textbook, the ** given, the experiments and the teacher's demonstration experiments.
The main aspects of observation are: the conditions under which physical phenomena or facts arise, the forms in which they manifest themselves, such as motion, deformation, temperature changes, results, etc. Secondly, we should consciously cultivate our habits and interests in observing physical phenomena in our lives.
2.It is necessary to pay attention to learning and summarizing the problem-solving methods of physics to help oneself gradually improve one's thinking ability. There is no special chapter in physics textbooks that introduces the learning methods of physics.
However, it can be said that the whole textbook is about the problem solving method of physics. This is because when textbooks explain physical concepts, laws, and formulas, they follow the steps of physics to solve problems. That is, questions are generally raised first, and then carried out through experimental research, observation, analytical reasoning, generalization and other steps.
Therefore, in the whole process of physics learning, while learning the problem-solving steps of the textbook, you should also pay attention to thinking to see if you can come up with experiments, methods and steps to solve the problem that are different from those in the textbook. In this way, while learning to inherit the thinking achievements of predecessors, they can also exercise and improve their ability to solve problems and innovate ability.
3.Pay attention to the method of memorization. Although learning junior high school physics requires attention to cultivating thinking ability, it is also necessary to pay attention to memory, and to memorize on the basis of understanding, rather than mechanical memory.
When memorizing, we should pay attention to finding patterns and characteristics, and be accurate. It is necessary to accurately memorize the various definitions, the literal expressions of the laws, and the "units" of various physical quantities. This is conducive to helping us form the ability to express physical words and language.
One of the biggest differences between physical formulas and mathematical formulas is that each factor in the formula has a "unit". Therefore, when memorizing the expressions of physical formulas, it is important to remember the physical units of each factor.
4.It is necessary to pay attention to experimentation and do as many experiments as possible. If you can't do experiments, you can't say that you have learned physics well.
Experimental hands-on ability mainly refers to hands-on ability such as observation, operation and production. When you start learning physics, you can pay attention to how the teacher does all kinds of demonstration experiments, such as the steps of the experiment, what to do first, what to do later, and the method of the experiment. When doing experiments, carefully experiment and practice according to the experimental steps and methods required by the teacher.
We should actively find ways to do the exploratory experiments and small productions on learning physical concepts and laws given by teachers and textbooks. This is very beneficial for enhancing hands-on ability. In addition, you can design your own experiments.
For example, if you want to design the experimental procedures and methods implicit in the illustrations and exercises in the textbook, you can design the experimental procedures and methods by yourself and conduct experiments. This develops your ability to innovate and solve problems hands-on.

Read the book, read carefully, there will always be a harvest, if you really don't understand it, buy a reference book, there will be a harvest, what you need is immediate action, defeat laziness, the problem is solved.
-
First learn to think rationally. Solve problems with rational thinking.
-
Buy some reference materials and learn all the subjects on your own, I am a typical self-taught person who understands all subjects. The key is to take good notes on the notes provided by the teacher first, and then understand and read more books. I understood a lot of knowledge.
The grades can still go up. For calculation problems, find a few example problems to see how people standardize the format of problem solving.
-
It's very simple, you can understand it by heart, and if you really don't understand, ask the teacher.
-
The exercises in the book are understandable and serious. Get another reference book and write it slowly, and that's it.
The first thing to do in physics learning is interest, pay more attention to the physical phenomena in life, ask more why, specifically in learning, conceptual things, especially formulas, must be understood, attention is understanding, not rote memorization, for example, specific heat capacity, it is a property of the object, and what has nothing to do with what, what is the formula of specific heat capacity. >>>More
I don't think there's a trick but rote memorization, and biology in junior high school is all knowledge, unlike high school, which has to be analyzed, so it's no problem to memorize it. >>>More
The speed of a black hole is superluminous. At the speed of a black hole, light is invisible. The speed at which a black hole moves is immeasurable, and the rotation speed of a giant black hole is about 45% of the speed of light. >>>More
Try to do the type of questions, the same type of questions, you can basically pass all of them if you pass one. When you do a new type of problem for the first time, you can spend more time and detour more so that you can thoroughly understand the routine of solving this type of problem and discover the trick. When doing a question, you should associate all aspects of knowledge and review it all the time. >>>More
Both motion and rest are relative to the referent.
Motion is the form of existence and intrinsic property of matter. It includes all the changes and processes in the universe. Dialectical materialism holds that the world is material, and matter is in eternal motion. >>>More
