The key is to memorize, memorize some special chemicals, and then use them flexibly, but also to organize your own set of mistakes, there are many skills, and I can't finish it for a while! , It is recommended to read more books, everything changes from their origins, and they are doing some questions, which is not very difficult, come on!
-
Memorize the periodic table, then memorize the examples in each book and learn to push the formulas.

1.Mathematics, physics and chemistry, so if you want to learn chemistry well, you must first learn mathematics well, and secondly, you should listen carefully in class, and actively think about why the teacher said this, because chemistry belongs to science, and the key to learning science well is to know the principles, not just memorize knowledge like liberal arts.
2.Of course, you can't listen to a lecture without being distracted, so you need to preview before class, and you need to pay attention to it when previewing, not just like reading for literacy, but thinking about why the book says this, if you can think about it, you can ignore it; If you can't figure it out, you need to make a mark, so that you can listen to the lecture in a targeted and efficient manner.
3.After class, you should review the content of the teacher in time, summarize the reasons why the teacher said the knowledge points you don't know, and if you haven't understood it, you need to ask the teacher and classmates for advice in time. And pay attention to collect the questions that you have done wrong, and the purpose of collecting is to do it again, not just look at it and not do it.
4.Once you've done that, it's time to prepare for the exam. The exam not only tests your mastery of knowledge, but also your mindset.
If you are overly nervous during the exam, you will basically forget what you have learned, so you should take a light look at the exam, but also have a correct attitude, finish the questions you can do, put aside what you can't do, and wait until you have completed all the questions you can do before thinking about how to solve the problems on the test paper for you.
5.Chemistry is a highly theoretical subject, and whether the theory is established or not needs to be supported by experiments, so you must do the experiments correctly under the guidance of the teacher. This is also a compulsory part of the chemistry exam.

Personally, I think that chemistry and physics are more technical!
If you have a good grade in junior high school chemistry, you can prepare, review, do exercises and ask questions step by step.
If the junior high school grades are above the average level, it is best to ask a good chemistry teacher who is a professional to tutor, preferably an in-service chemistry teacher, which can save time and improve faster, and you can also save time to study other subjects, because there are too many things to learn, so you can use the quick way to use the quick way, don't wait for the third year of high school and then worry!!
Purely empirical, think about it!!
Finally, good luck!!

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.

In the first year of high school, remember more experiments in the book, the specifications and functions of each operation step, and the role and characteristics of each experimental equipment, make good use of every opportunity to take experimental classes, try to do it yourself, and ask questions if you don't understand. Keep in mind every chemical equation that appears in the book, you can write it silently, or you can try to balance it yourself, if you are afraid of getting confused, you can classify and sort out some equations and some rules and techniques in the book and the teacher, and the experimental phenomena.
Well, that's all I've got in mind so far, and I hope it can help you.

Understand the memory and, if necessary, memorize some necessary death theorems.
This, this... Take good notes, straighten it out, chemistry is the liberal arts in science.
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.
