I started my junior year of junior high school in the summer, and I was very worried about physics a

I had just graduated from junior high school, and I was worried that I wouldn't be able to keep up, but I felt more relaxed after I started studying. Some small suggestions, the periodic table of chemistry is very important, of course, in junior high school is not to fully grasp it, take advantage of the summer vacation to preview the first 20 elements, try to memorize their symbols in advance, and you can also find the rules by the way. Then there are the equations, although there are very few chemistry equations in junior high school, and you can cope with the exam by memorizing, but a thorough understanding will help you study more smoothly in high school.

The core of physics in junior high school is electricity, focusing on understanding.

Don't worry about the third year of junior high school, just study hard, it's nothing. Physics and chemistry are well understood, and after understanding, do a few questions to consolidate it, make a mistake book, and flip through it from time to time.

It's okay to listen carefully to chemistry classes in the third year of junior high school.

Memorize chemical and physical formulas. Try to understand what you don't understand. I'm pretty good at chemistry.

Chemistry learns trim well, physical circuits, in fact, these keys depend on your understanding

Listen carefully in class, find some test papers or materials to do questions, and slowly accumulate experience and understanding, and your grades will slowly improve. There are no other shortcuts.

Physics will be a little difficult, you can take a prerequisite or learn it by yourself Make up for your previous knowledge Do more questions The high school exam questions in various provinces Chemistry As long as you listen carefully in class Do homework No problem Hand ask for praise.

In physics, you should memorize all the formulas, then do more problems, practice more, practice makes perfect. It's the same with chemistry, first grasp what is in the textbook, and then rely on the accumulation of questions to improve your grades.

Don't worry, physics and chemistry are easy in the third year of junior high school.

Just ask a professional teacher to make up the class during the summer vacation.

Listen carefully from the first class, and if you don't listen halfway, find a teacher.

Work hard, it's up to you to work hard.

Me too. In short, keep an interest in it.

Summary. The solutions to the problem of not understanding chemistry in the third year of junior high school are as follows: 1. First of all, listen carefully, follow the teacher's lecture ideas, and consolidate the knowledge points that you have missed before for intensive learning.

2. Do questions according to the knowledge points taught by the teacher, and consolidate and review the knowledge points by doing questions. 3. Strengthen the memory of the knowledge points that are not well remembered, and take good notes for many reviews and memorization. 4. In junior high school chemistry, you must read more and memorize more and memorize the knowledge points firmly.

Hello, are you just in the third year of junior high school?

On after the summer vacation. I've been studying well, but I don't know much because I studied chemistry in advance.

Hello, when I first started taking the chemistry course, it was normal that I didn't understand. Because the new machine needs to laugh at a thing, and it takes time to accept it early. The chemistry of the third year of junior high school is stupid and stupid.

As long as you go to class, follow the teacher's train of thought. Come up and be diligent in reviewing and doing questions. A lot of progress will definitely be made.

The solutions to the problem of not understanding chemistry in the third year of junior high school are as follows: 1. First of all, listen carefully, closely follow the teacher's lecture ideas, and strengthen the learning from the knowledge points that you have missed before. 2. Do questions according to the knowledge points taught by the teacher, and consolidate and review the knowledge points through high school and early school.

3. Strengthen the memory of the knowledge points that are not well remembered, and take good notes for many reviews and memorization. 4. In junior high school chemistry, you must read more and memorize more, and you can memorize the knowledge points firmly. <>

For junior high school chemistry and physics textbooks are the key, read the textbook thoroughly, understand it, write down all the things that should be remembered, and be sure to listen carefully in class, don't listen to it well because you don't like the teacher, so it's almost the same.

The knowledge of the third year of junior high school is not difficult The concept is the most important Experiment** There is nothing else It is easy to score more than 67 points (out of 70).

It's not difficult, it's not difficult at all, lay a good foundation first, and you will feel uncomfortable at first, because this is a new discipline and I don't know it. But it's very interesting, as soon as you memorize the knowledge and repeat it more, you will feel that the more you learn, the easier it will be, and you will do more classic questions. Ask the teacher more, and if you don't understand, you must ask to understand, and you will feel very simple.

I hope you can learn very well, and after you finish the third year of junior high school, you will feel that what I said makes sense and have a personal experience. Physics is easier than chemistry, and doing more questions will help you. Come on, preview and preview first, so that you know what to expect.

Preview before class, listen carefully in class, and you're done.

Chemistry in the third year of junior high school is not difficult, read more books, do more questions, and mainly memorize things; Relatively speaking, physics is a little more difficult, and the circuit in physics is a little simpler, so you must first learn mechanics, and being proficient will help you learn in the future, and then attack the circuit.

Science in junior high school is not difficult, the main thing is the basic knowledge, and then add a little physics calculation is more annoying, overall as long as you listen carefully in class, do your homework seriously (I was like this at the beginning, all the materials are only textbooks and teaching aids issued by the teacher, at most plus a teaching aid for the main knowledge, but the grades are OK, basically will not fall off the top three.) Hey. However, there are some people in the class who also take big classes outside, and the effect is not very good, so if you want to go to tutoring, you can choose a better middle school teacher or directly find a high school teacher to take it.

If you want to rank in the grade, I advise you to participate in the school's improvement class, even if it is just an audit, those teachers have a very good method. If you don't have it, buy some competition tutorial books by yourself, it's best to have detailed answers, not a lot, you can grind a paper every week, which is very helpful for thinking training (it also works in mathematics). Also, it is also very important to do a little bit of high school exam questions in advance to train your problem-solving speed, and it is best to set a time when doing the test paper.

I don't remember the rest very well, I wish you success in the high school entrance examination. (Note: I'm a student in Hangzhou, so I don't know if it's useful to you, but that's how I got mixed up with Chonggao at the time.) Haha)

Physics is not too difficult, but you must be attentive, and each unit has some fixed methods of problem solving, you can try to summarize by yourself, and the more you summarize, you will naturally become interested in physics.

Don't be afraid to use your brain, the more you use your brain, the better it is, and now you need to pay attention to observing life, and there is physics everywhere in life. In addition, you can also take a look at CCTV's ten sets of night science and technology light, which has a lot of physics-related things, which is very interesting and can cultivate interest.

The questions must be done, and the teacher can help you choose a few questions, and you must use the knowledge you usually learn to solve the problem. There are also many students in our class who have copied a lot of notes, and physics is still very poor. I barely took any notes, but I was still the physics class representative.

The key is to use, do more questions, and understand the ideas of the questioners, and it will be easy to learn. For example, I sometimes know what question to ask just by looking at the stem. It is necessary to do more exercises, but to do more exercises, but to be fine.

For each question, you must first carefully review the question to understand the true meaning of the question, in fact, the question is not very difficult, since you can read the answer to complete the exercise, one possibility means that you will do this question, but you have no confidence in yourself, you have to try to do it, build confidence. Another possibility is that you don't have a good grasp of how to do the problem, which requires you to do some typical example problems and draw inferences. After completing the exercises, it is not necessary to correct the answers or give them to the teacher to correct.

You should think about yourself, is the order of magnitude right for the answer? Are the physical processes reflected reasonable? Can you tell if your answer is correct from another angle?

We have to try to be so good that either we can't do the exercise, and if we do, we have good reason to believe that it's right, even if it's not the same as the answer given in the book. The teacher says you're wrong, and you dare to argue with the teacher before you're convinced. What a good teacher appreciates most is a student who can point out his mistakes.

If it turns out that you are wrong, you will be wrong.

Whether it is a mechanical problem or an electrical problem, after encountering a calculation problem with a certain degree of difficulty, it is necessary not only to carefully review the problem, but also to draw a diagram, so as to establish an intuitive physical situation.

Find out how to solve the problemTwo methods are generally used to solve physical calculation problems, namely the analytical method and the synthesis method. The former is to use physical formulas to solve from the known to the unknown step by step, and the latter is to list physical equations to solve under specific conditions. There is also a proportional method, which uses the proportional method to solve, and its process is simpler and has the effect of getting twice the result with half the effort.

When actually doing the questions to avoid arithmetic errors, some students can only do simple calculation questions, but they are helpless in the face of flexible questions and comprehensive questions with many level changes. Therefore, candidates should not only learn physics knowledge seriously, but also strive to improve their mathematical reasoning ability. Don't let the correct answer slip by because of a miscalculation.

Junior high school is a circuit, I remember it seems to be, as long as you figure out the essence, everything will not be separated from it.

Do more, and after telling you, you will understand that doing more will make your thinking more logical.

The physics of the third year of junior high school mainly talks about the content related to electricity, circuits or something, the key is to listen carefully to the lectures, but also to think more, the changes of circuits and the solution of related quantities, the most important thing is to really understand, so that many problems can be easily solved, of course, it is necessary to do certain exercises.

In fact, learning physics must be done more practice, and then the most important thing is psychological suggestion, don't limit yourself to a certain range of grades, think that you are good at physics, and one day you will really find that you are good at physics

The key to physics is to understand the concepts and principles very well, do each question to be thoroughly clear, find the entry point of thinking about the problem, which will be of great help to your high school physics study, and finally wish you good results in the high school entrance examination.

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way: a vacuum is really empty, there is nothing.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.

Chemistry in junior high school is ......A science ...... with a very strong liberal arts natureTherefore, you must memorize more and memorize ...... frequentlyThe equation should be memorized, and three things should be paid attention to (trim, condition, gas precipitation symbol).

The physics of the third year of junior high school is mainly focused on buoyancy and mechanical efficiency, which is required for the high school entrance examination (choose one of the two, or combine buoyancy and mechanical efficiency, this is difficult......So you need to put a lot of effort here, memorize the formulas, use them flexibly, and practice the exercises (especially the calculations) in this area ......

And ......The most fundamental ......If there is any interest in them......I guess it's not too hard to learn anything, right?

I just finished my ...... high school entrance exam this yearPhysics 78(85), Chemistry 63(65) ......

It's not difficult, just understand the knowledge and connect it with real life.

The junior high school is very simple... It's OK to understand

Understand the definition, find the rules, and practice more.

Listen to lectures in class and memorize more after class.

The knowledge in the book is basically very simple and can be understood. What the teacher talks about in class is the essence, so you must listen carefully in class. Also, you need to take a look at some typical examples!!

1. For understanding the basics: pay attention to the basics, read the book several times, understand the exercises after class, think more on the premise of passing the basic foundation, the topic will not do why, it is because you do not have a deep understanding of the content of the book, you may understand a simple theorem and a formula, but you can't think of it in the question, or think of this theorem but there is a problem in the operation, that is, because there is no deep understanding, I do not see clearly what the premise of the application of the theorem is, what conditions do I need to add when doing the problem? What conditions are created to make it feasible. If this piece is done well, then consolidate it through the examination of the reference book and the exercises, at this time, on the premise of knowing how to test a knowledge point, summarize the method and improve the ability, but in fact, this is still linked to the book, and at the same time think about the knowledge in the book again and deepen the understanding!

2. According to the characteristics of the course: after paying attention to the above, you should find that chemistry is heavy on changes when solving problems, so after understanding the basics, you will be more sensitive to the topic than others, and you will associate the knowledge points of design when you see something, and then deal with it flexibly; Physics heavy model, so you have to be familiar with the model, it is normal not to do some questions, read the answers and then think, if you want to get a high score, you have nothing to look at the questions you did before, read it a few times, and after a period of time, you can do it again without looking at the answers!

In this way, you can really learn things and get high scores!

Hope it helps! If you think it's good, add some points.
