In fact, it is not difficult, but I don't have any intentions, I must carefully read the textbook, especially the definition of each concept in the textbook, from the surface meaning must be excavated to the substantive meaning, which is the most important. As long as you can do this, and do some questions appropriately, you should improve quickly.

In this state, you might as well study literature. In fact, high school chemistry is a basic reflection of some inorganic substances, and if you remember a few special cases in the book, you will not get a low score if you know how to balance the reaction equation.

Eh, I'm a liberal arts major, but if you're good at math and physics, chemistry shouldn't be bad, and you have to get interested in it. For example, how did this chemical reaction come about? You just memorize those important chemical formulas slowly It helps, I originally wanted to choose science, but then I didn't because physics didn't work. Come on.

High school chemistry is actually quite interesting, but it may require a slightly larger amount of memory, you say that your Chinese English is good then this should not be a problem, if you are pressed for time, you can quickly improve through the sea of questions tactics, but be careful, a solid foundation is the most important.

Remedies for bad chemistry:
1. Listen to every class.
Listening to lectures is the core part of learning the chemical process, and it is the main way to learn and master knowledge. Especially in chemistry, a lot of knowledge is the basis of the next lesson, if the child does not master the next lesson, it will become an obstacle to learning, so whether the classroom can master the knowledge learned is the key to determine the learning effect.
2. Strive to express yourself more in class.
Children are expected to share their understanding with the teacher in class. You must know that the content of chemistry class is interlocking in many cases, and if you do not fully understand the previous ones, it may lead to the following being more difficult to understand, and eventually lead to the failure of the lecture, and if you do not remedy it in time after class, you will gradually become a "poor student".
Therefore, even if the child does not understand correctly, the teacher can provide the right ideas, which is very helpful for the child to grasp the knowledge points.
3. Find out what you know and what you want, and calculate more points step by step.
When children are calculating, the chemical equation should be written completely, do not write the chemical formula incorrectly, balance it, and pay attention to the reaction conditions and whether the product should be marked with an upward and downward arrow. The relative atomic mass should be calculated at least twice on the test paper, and the process of children's calculation should be completed on scratch paper, which must be simplified first, and then calculated, at least twice.
4. Preview is very important.
Children should know in advance what the teacher is going to teach, which is really helpful for learning chemistry well. In high school, some teachers will speak very quickly in order to catch up with the progress, and they can't keep up with it and there is no preview, which is likely to cause most of the children to be confused when they listen to this lesson, and it will take you more time to make up for the parts that you don't understand after class, so the child must do a good job of preview in advance.
5. The principle of doing questions.
If the child encounters a difficult topic and still has no idea after a few minutes of thinking, then he should put it aside for a while and start working on other problems, so that he must not waste a lot of time because of one question, so that the later questions cannot be completed with quality and quantity. It would be a shame if the child had an impact on their overall score for such reasons.
When children are looking for ways to remedy chemistry problems, they should also know that learning any subject well is not achieved overnight, which takes a lot of time and experience.

1. For high school students who have a poor foundation in chemistry, it is first necessary to make it clear that no matter what chemical reaction it is, it must be considered from the perspective of the periodic table. The reaction principle of chemistry and the valency of the state of matter are basically in line with the distribution law of the periodic table. Therefore, high school students can prepare a notebook for learning chemistry and record some irregularities, including all the special colors, precipitation, valence and other values of the reaction of the elements or reactions.
2. Secondly, many high school students who do not have a good foundation in chemistry do not remember the knowledge points of special elements and equations very clearly. But in fact, these are very important, such as the reaction can produce special gases, precipitates or color elements are the key points of high school chemistry test and problem solving.
3. Compared with other subjects, high school chemistry knowledge and test points are really not very much, so it is feasible to work hard and improve your grades in the short term. But remember not to wait until before the exam to surprise again, so that even if you are smart, it is useless, and the premise of improving your score in the short term is that you have the foundation and preparation. Therefore, if high school students want to learn chemistry well, they must lay a good foundation, remember, start now and persevere, and success will be yours.
4. The last and most important point for high school students to learn chemistry well is to listen carefully in class. Only by concentrating and taking the initiative to learn can you become interested in chemistry and eventually learn chemistry well. When the teacher imparts new knowledge, high school students should think about how the teacher analyzes the problem and be able to follow the teacher's train of thought.
When the teacher summarizes the content of this lesson, it is necessary to pay attention to the learning focus of this lesson.

First of all, we must pay attention to the basics, the basic knowledge on the book should be familiar, and we must read the book repeatedly, like the college entrance examination questions are ** in the book, so the reference book is just a reference, and the textbook is the basic, when there is something unclear, it is necessary to read it repeatedly, and repeatedly familiarize yourself with the memory.
Second, we must ensure a certain amount of exercise training, exercise training is very important, science questions are very important, one can help you get familiar with the knowledge, and the other can allow you to find your own weak points. You must ensure a certain amount of exercises, but the more the better, and you must be good at checking and filling in the gaps. When revising, it will be very effective to turn over the questions that you have done wrong in the past and take a look.
Third, although the knowledge of chemistry is not difficult, there are many knowledge points and complex knowledge, so we must form a network of knowledge, for example, the similarity and progression of the properties of each main group element is a knowledge system. Be good at summarizing knowledge, so that it will be easier to remember.
Fourth, be sure to communicate with teachers more!! When you study chemistry, you will find that there are some questions that you have been thinking about and never understanding, but after consulting the teacher, it will suddenly become clear, so don't do it behind closed doors, and communicate more with teachers and classmates.
Finally, if you really find it difficult to learn, you can go out to make up for classes, go to your own teacher or some cram schools outside, I think it is still very useful

Oh, I'd love to help you.
First of all, congratulations to you, because you have not given up on studying, and you are still interested in chemistry.
Chemistry is not difficult but you need to be careful and serious, because the content is numerous and complex, and it is not difficult because there are rules to follow and you are interested in research; You need to be serious because there are too many trivial knowledge points in chemistry terms, and you need to carefully compare, ponder, and study them to distinguish them.
It is recommended that you start with your interest, do some basic questions, do and compare repeatedly, and consolidate the basic concepts (such as distinguishing between oxidants and reducing agents, positive and negative electrodes, cathodes and anodes, and reactions between various substances, etc.) to the extent that practice makes perfect, so that your interest in chemistry will also increase greatly; Do some more difficult questions, at this time, it is not much, but to think about what knowledge is being tested and how to test the question. Slowly overcoming every obstacle is your growth, your progress, and then do some comprehensive test questions.
