How can I improve my chemistry score quickly?

1. Listen carefully and take good notes. Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process. Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review.

2. Review in a timely manner. Revision is not just a simple review of knowledge, but considering the interconnection of old and new knowledge in one's own brain, and reorganizing it to form a new body of knowledge. Therefore, after class, it is necessary to review the content of the lecture in a timely manner, and do a good job of sorting out and summarizing the knowledge, so as to make the knowledge integrate and avoid the phenomenon of more and more chaos in learning.

For example, if you learn about the bleaching properties of SO2 and chlorine water, you can compare them to find out the differences. 3. Learn to memorize because there are many chemical knowledge points to be memorized, it is difficult to memorize if you rely on rote memorization, so you should learn to memorize skillfully. Commonly used memorization methods in chemistry are:

Comparative method (often used for confusing and interfering knowledge.) The four similar concepts of isotope, allotrope, homologue, and isomer can be deepened and remembered through comparison. ), induction, song recipe memory, comprehension memory, and experimental memory.

4. Practice is an important way to understand, digest and consolidate classroom knowledge. However, the practice should be targeted, not a sea of tactics, and should be aimed at mastering the basic methods and the rules of problem solving. In the process of problem solving, it is necessary to pay attention to multiple solutions and inductive summarization of one problem, so as to achieve the effect of doing one problem and one category.

For example, the techniques commonly used in chemical calculation include: conservation method, relational method, extreme value method, average value method, estimation method, difference method, etc. 5. Prepare a "Mistake Book" The purpose of doing questions is to cultivate ability, find your weaknesses and shortcomings, and find an effective way to do so.

Therefore, mistakes should be corrected and recorded. When recording, you should analyze the reasons for the error and the correct solution idea in detail, and do not simply write an answer. At the same time, it is important to go through the review frequently so that you can avoid similar mistakes in the future.

6. Pay attention to chemical experiments Chemistry experiments can not only cultivate students' ability to observe, think, and practice, but also deepen their knowledge and understanding of relevant knowledge, so we must pay attention to chemical experiments. When doing experiments, we should ask a few more whys, think about how to do it, why we do it, and what else can be done, so as to achieve the purpose of "knowing what it is and why it is true". In addition, in order to study chemistry well, we should pay more attention to social hot issues and life problems related to chemistry, and be good at combining book knowledge with practice.

If you don't understand what the teacher says, you should pay attention to the pre-class preview It's best not to just read the book, so just looking at those lines may not be helpful It's best to buy a tutorial book Look at it first The things the teacher talks about are probably similar to the ones in it You read first Find what you don't understand Make a mark When you go to class, you will concentrate on listening, so that your learning will be very active, and you will find the fun of chemistry courses Regarding the review after class, I think that what you have learned is divided into topics to review, which is both efficient and hierarchical It's best to classify the questions that you are wrong Some of them are things you don't understand and you have to sort them out Some of them are careless There are reasons for your carelessness Some of them are because you don't have a firm grasp Some of them are your own calculation problems These should be summarized It is very effective to take it out before the exam Although for the first year of high school (you should be a freshman or sophomore in high school. Maybe this is too dense to learn, but at first it is a little tiring, after a period of time, you will feel that you need to organize less and less things, but the knowledge is getting clearer, if you have integrated to do comprehensive problems, you should pay attention to induction, especially experiments, many experimental terms are better to remember, because you can be set in other topics, don't think that chemistry is science, you don't need to memorize, in fact, sometimes you have to properly memorize some fixed collocations, of course, understanding is also very important, such as the washing steps of precipitation, the process of extraction The steps needed in the process of making a pure product These are best to have a spectrum in your heart, and at the same time pay attention to chemical experiments, do a good job of industrial flow charts, these two parts of learning should look at more experimental questions, do more, you will find a lot of common places, organic topics, pay attention to the inductive summary after learning, the most important thing is how to break the bond and how to grow the organic synthesis of the carbon chain, and the related isomers, such as what can make the acidic potassium permanganate solution fade, or the problem of fading bromine water, is the oxidation reaction, the addition reaction It is still a simple extraction, and it is necessary to pay attention to the information provided in the topic of organic synthesis Regarding chemical equilibrium and chemical reaction rate, it is necessary to master the "three steps" As soon as the relationship is listed, many questions can be answered, and there are also related reaction images; Pay attention to the first turn and the first flat temperature and high pressure Regarding the periodic table, it is necessary to master some common usages and reaction phenomena of the first 20 elements; When it comes to related topics, you can list the top 20 elements and then check them; As for the material structure of the elective module, read more books and master the unit cell and other issues Pay attention to the density calculations, elements and their compounds, and also summarize them, when you can form a knowledge network, you will find that everything is well understood, don't be too troublesome, it may take a little time at first, but when others get tired before the exam, you can easily deal with it, I think association is also very important, a association can combine a lot of knowledge! In fact, there are commonalities between subjects, and individuals have their own learning methods, not necessarily mine, and it is the truth that all those who do well in the exams come this way, because I am from X chemistry, and this is indeed a bit harsh on students who are not X chemistry.

If it is for the exam, then it is enough to do the mock questions issued by the authority, do it in the specified time, analyze the cause of the error afterwards, and ask the teacher in time if you don't understand the analysis. If you want to improve your chemistry level and are really not afraid of exams, then you should start by cultivating your interest, in fact, chemistry is very close to life, first read some extracurricular books, popular science, and slowly find the feeling, and it will be easy to learn.
