What happened to 200 days? It's impossible to be top-notch, but to reach the foundation, time is still enough, and I'm also a senior in high school, so I'm ashamed to say that I have no strengths except chemistry.
First of all, the basic equation, this needs to be memorized systematically, to classify memory, it is best to borrow classmates' notes to read, don't read books, that thing is too messy. To be proficient in the common test element equations, such as chloride, aluminum, sodium, oxysulfur, nitrogen, etc., of course, the premise is that you have a good foundation in chemistry in junior high school.
Then, focus on memorizing some contents, such as the verification method, preparation method, reaction conditions, etc.
Furthermore, to study the essence of the equation, to find the law, you can't just memorize, the key is to be able to push it yourself.
The above is the basics of chemistry, it is recommended to find classmates to help you, and you can also find me if you have any questions.
Good luck.

Read more textbooks, buy a reference book, and read through.
-
Go memorize the past college entrance examination questions! Key knowledge memorized, except for crazy backing is crazy backing.
-
The fastest way is to do typical questions, that is, representative questions, and look for the rules of questions and the inference of chemical substances, because chemistry exams often ask questions about chemicals that have never been seen before! I also graduated from high school chemistry!
-
Although the tactics of the sea of questions are very stupid, it is easy to solve them when they encounter similar problems. Of course, you have to understand the textbook, extend it, and apply it lively.

You're too strong too. This can't be rushed.,You can find a more concise book to read and then learn it slowly little by little If you can't do it, just memorize it.,There's very little chemistry in high school.。。。

High school chemistry is to learn those equations, learn them thoroughly, and you have to memorize every transformation, and reflect how they work, and you can know how they are going even if you haven't learned the principles, so that there will be no problems, even if it's the reasoning problems later, and the key is in those equations.

I'm still in love with the name.
1. Attend lectures. 2. Do the questions.
3. Review. 4. Summary.
-
Lay a solid foundation, such as high school chemistry inorganic, various reaction laws are the key, for example: reactions in solution, always in the direction of reducing ions in the solution!
-
No tricks. Pay attention to what the teacher says, and ask questions if you don't understand, which is the king.
-
Memorize more basic knowledge, chemistry knowledge is very "scattered", I have been a representative of chemistry class for four years (from the third year of junior high school), I am interested in chemistry, so it is very easy to learn, in general, learning chemistry first cultivates interest, but you will soon be in the third year of high school, and now you have to memorize more.
-
Back to chemical equations.
Back to the basic concept Chemistry is the process of accumulation, and when you really understand the fun of it, it will naturally improve. Interest is always the best teacher.
-
Memorize more basic knowledge, summarize in time, do some college entrance examination questions to consolidate, don't know how to ask more, the most important thing is to be attentive...

You also have to make it clear which elective modules are tested in your province, I will first say some of the must-take, the three or four chapters of the compulsory part 1 of the elemental chemical equations are written proficiently during the holidays It is best to summarize some rules by yourself For example, metal element-oxide-hydroxide-salt Write according to this main line Mutual conversion of sodium, aluminum, and iron A round of review materials is basically summarized It is recommended that you buy this "Five-Three" to fill in the knowledge framework inside, and stick to it for a period of time It will get better, and it is the best choice to find your teacher in the third year of high school.
To learn chemistry, you should first take out the entire high school chemistry book for analysis, and the chemistry content in high school can be roughly divided into three aspects: organic, inorganic, and structural. You can analyze it through your own test paper to see if that part of the knowledge is not good, and I can try to help you. >>>More
You're not a robot, and someone else's approach may not be right for you. >>>More
Let's do more questions, and there are notes, and I have to do it in the book, and the exercises taught by the teacher have to be memorized, I'm stupid, don't they all say that a good memory is not as good as a bad pen, I don't have a total score of 100 in high school chemistry, but I don't look for questions to do, just do the teacher's assignment, never copy Our school is just a general high-quality high school, and if you do more, you will master the rules of solving many problems, and then there will be a lot of shortcuts and tricks Chemistry is a very ok subject I like it very much, I hope you will improve in the future Come on.
In the study of mathematics, the learning of mathematical concepts is undoubtedly the top priority. Nothing can be done. However, this point is another difficult point. >>>More
Personally, I think it's best for you to take a while, go through the content of the first year of high school from beginning to end according to the teacher's teaching and explanation order, remember the content of each knowledge point, understand the relationship between each knowledge point, and strengthen the practice of comprehensive questions and inference questions (in these questions, don't blindly pursue the answer, only the end of the first year of high school, there is still time, you must figure out every "specific detail", and be sure to summarize and classify, such as inferring that most of the reactants in the yellow powder are sodium peroxide, and most of the products are sulfur elements, etc.) Consolidate the basic knowledge through these ways, and at the same time deeply understand the words """ and "conservation" in chemistry, grasp the conservation relations (such as elements, charges, etc.), and gradually you will find that all the topics are actually using various conservation relations. This makes it easy to solve the problem. In addition, it goes without saying that you should listen carefully in class, take good notes, many things are not in the textbook, and ask teachers and classmates to solve the questions in your heart in time. >>>More
