I have the most say in this. When I was in high school, chemistry was always invincible. Basically, it's 85 points or more. The landlord may wish to give it a try.
First of all, chemistry is a discipline with scattered knowledge. Such as chemical properties, chemical equations, and so on. Don't be too ambitious when learning chemistry, you must start with the simplest knowledge points, and after each class, you must classify the knowledge points you have learned.
For example, according to the oxidation of a substance, which substances can it react with, and then write out these chemical equations one by one, and so on... As long as you study carefully, you will definitely be able to classify and memorize what you have learned. I feel that I remember almost, which means that I can try to write example problems after I know the properties of the substances I have learned.
Secondly, it is to write the question. Have you found that the biggest feature of chemistry questions is that the questions are closely related to the knowledge points? There isn't much emotional awareness.
Unlike mathematics, sometimes you can understand and solve difficult problems with perceptual awareness. Chemistry means that if you know a certain knowledge point, you will write this question, and if you don't know, you will not write. The vast majority of chemistry questions are based on memory.
Therefore, the memory fragmentary knowledge points I just mentioned are the basis and premise of your writing questions, and you must memorize them carefully. But chemistry topics are very regular. Because you'll find it easy to divide the questions into several fixed question types.
And these types of questions are often mostly reflected in the example questions. Therefore, it has become another key to do the example problems carefully. Do chemistry questions not too much but fine, carefully experience each example problem, learn to understand thoroughly, and grasp the key to each example problem.
The popular point is that there must be an idea when you encounter this type in the future. I remember that when I was in high school, I never finished the chemistry workbook, but I always got high scores, just because I didn't seek more, but I wanted to be refined.
If you do the above requirements, you will be more than half successful, and the rest is to quickly look through the past bits and pieces of knowledge before each small and large exam. If you have time, you can also take a look at the example questions written in the past. Guaranteed you chemistry worry-free. I wish the landlord the title of the gold list.

First of all, you should know that chemistry is a liberal arts within the sciences.
If you want to score 80 or 90, you have to memorize it. Remember.
If you want to break through 110, then you need to increase your logical thinking ability (the value may vary from place to place).
Chemistry is very difficult at first, you have to persevere, you can't ask the teacher, and you can ask the tutor if you have the conditions (in fact, there is no need).
Go back often, read books (teaching aids are necessary), and the books in the school library should be pretty good.
In short, have faith!!

The way to learn is to organize.
1 Summarize the highlights of each chapter.
2. Integrate similar content, especially similarities and differences (very important).
3 In the end, he finished the question summary, and there were few knowledge points in high school, so he only tested those typical ones.
You don't need to prepare a book, just a few larger pieces of paper, and organize them and clip them in the book for easy reading. I used to be directly on the blank paper of the first and second pages of the book...
In fact, it is a waste of time to sort out this step, especially if you pay attention not to copy the book. When I used to take notes, I copied the key points of the book as they were, but the effect was really small, so it was better to read the book several times and organize it into categories!!
I think it's hard to learn that in the end of science, you can find a thread that allows you to string together everything you've learned, but it's very effective! Mathematics, physics, chemistry and biology are all effective.
Chemistry is not difficult, it doesn't matter if you don't study hard in class, just have enough self-learning ability! I don't know if this is a quick way to do it, but I still hope you stick to it, learning is not an overnight thing. If you have a better and more suitable method for you, please stick to it, if not, mine is available for reference.

In fact, high school chemistry is not so scary, as long as it is studied systematically. For example, the oxidation of the elements can be compared, and the stronger oxidation can be put together, and the relationship between the strength and weakness of these elements can be clearly and effectively remembered by remembering the reactions between these elements. There is no need to memorize the equation by rote, as long as you remember whether the price of the element increases or decreases in the reaction, and then the coefficient relationship can be determined according to the amount of increase and decrease.
Look at some more questions, chemistry 85 or above is still okay.

It depends on whether you study literature or science, and the literature should be examined, as long as it is reacted, I don't know, I am a liberal arts student.

I am a recent graduate and have a deep understanding of chemistry learning.
1.Learning focuses on accumulation, especially in chemistry, in fact, everyone has accumulated common knowledge in life, which is very useful for chemistry.
2.Attending classes is necessary, every course is the same, class time is very precious, and every teacher will do their best to introduce their knowledge to everyone during the class, so the class has almost become the time to communicate with the teacher the most.
3.Homework should be completed in a timely manner, and the teacher will carefully design the homework to help students understand and experience the key content of the class.
4.Q&A and self-study, don't do questions from the teacher! This will affect your independent thinking, self-study is not very necessary, especially blindly doing questions, not only delay time but also fail to grasp the key points, so if you feel that a part is not clear, you can ask the teacher, or ask the teacher to help choose some questions to do, the teacher will be very patient.
Mistakes are a must-see, and they are worth watching.
The above are my thoughts on chemistry learning, which are relatively superficial, but I hope they can help you, classmates, and most importantly, self-confidence!! Hold on to chemistry.

Chemistry is a very trivial science subject There are a lot of things that need to be memorized or memorized A bit like liberal arts There are many things that need to be summarized such as the law of gradual change of elements and so on Accumulating knowledge is one thing On the other hand, it is necessary to practice more Purposeful practice The same type of problem can be done 2-3 times Doing more is equal to wasting time Summarize the tricks of solving various problems Rote memorization concepts and chemical reaction phenomena must be remembered This is like building a house and laying a foundation The foundation is stable The house can be built high It is best to have a special notebook Classify and filter what the teacher says, classify them by echelon, find teachers more when you have time, ask teachers more questions, don't know what to ask, just listen to others, there are always things you don't understand.
-
Grasp the basics and learn the basics.
Carefully review the questions, identify the concepts, answer the questions carefully, summarize in time, and look for the cause of the error.
The important properties of several elements should be mastered, and the principles of chemical reactions should be mastered.
-
Preview the basics.
Identify concepts. Review the questions carefully.
Answer the questions carefully. Summarize in a timely manner.
Look for the cause of the error.

1.If you have a good foundation, on the premise of mastering what the teacher says, preview in advance, so that you will have a sense of accomplishment and will get better and better, and in the process of listening to the teacher's lectures and doing problems, you will have a targeted listening to what you don't understand very well when you preview. I studied chemistry very well in high school, and I usually preview one or two chapters in advance, note that my preview is not simply reading the book, but completing all the materials and exercises in this chapter as if I am really studying, so that I can really understand this chapter.
Then, in the process of teaching the teacher, you can pick out some problems, do the questions that you have done wrong before, and complete the homework assigned by the teacher.
2.If the foundation is not good, then the first thing to overcome is the fear of difficulties, maybe you have not done well in chemistry, but try to complete an assignment or test paper well, no matter how to do your best. Then, even if you have a good grade in chemistry for a short time, you have to remember in the later learning process that you can learn it well, and you have learned it before.
As long as you pass the mental level, then I believe you will take action to improve your grades.
Whatever you study, be happy to learn, so that you will learn things and you will get results. May you learn happily and happily.

No matter how much preparation is the most important, after the preparation, you just need to listen carefully in class and take good notes, and then do the corresponding homework after class.
-
In my experience, I think you should read more textbooks, textbooks are the best things to use, a lot of things are in it, even if sometimes you feel that you have mastered almost, and then look at the textbooks or there is a harvest, after reading it, remember to do more exercises, [remember not to rush to see the answers], and pay attention to the class, summarize more, it will definitely help, we can also talk about it in detail... I've talked to others about this method, and they say it works very well. Good luck with your studies!!
In other words, although I didn't get a perfect score in chemistry, I never scored 96 (100).
-
Do more exercises, and ask teachers and classmates if you don't understand.
-
Memorize equations, principles, conservations. Do more questions.
-
How can this be explained in a few words? In terms of my almost perfect score in the chemistry college entrance examination, it is to pay attention to details. Remembering common reactions and phenomena can be very helpful in deducing molecular formulas.
There is also the periodic table that you must be familiar with, especially the top 20, which is a must. In short, be careful, many of the questions are about the details.
-
As a person who has gone through the years of high school, College Entrance Examination Science Comprehensive 263 Let me talk about experience, chemistry, you first write down the periodic table at the back of the book, this is a must, and it is very helpful for you to do inference questions later, believe me, and then there are chemical equations and phenomena, especially some special reactions and phenomena, you must be very proficient, and finally pay attention to the skills of calculation, and draw inferences.
Trust you, I'll do it my way, and it's going to be strong.

This question is too general to say, and I am a chemistry teacher, so I can't tell you in detail.
High school chemistry formulas are:Reaction of sulfur with sodium s+2na===na2s >>>More
