The way to learn is to organize.
1 Summarize the highlights of each chapter.
2 Synthesize similar content together, especially the similarities and differences (very important)3 Finally, the question is summarized, and there are few knowledge points in high school, so he only takes 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...
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.

Summarize the equation (you can ask the students who are better at learning or directly find the teacher to do a demonstration, and then follow the learning and summarize it yourself).
Summing up the multi-back.
Doing questions is a must for science students, so I won't say much more.
I have to read more textbooks, I buy delicious food when I choose breakfast, go back to the classroom, eat while reading a book, and look at as much as I want, just be careful not to make the book oily.
Look at it a little more carefully, and there are always some little things that you haven't noticed before.
My suggestion is that you don't look at mathematics and physics at this time, these two subjects are based on problems.
But biology and chemistry are right at this time, because most of the time given by the teacher is usually the time to do the questions, but these two subjects require textbook knowledge very much, and the effect is better if you do this) (a bit off topic).
Then there is a mistake book, just remember the wrong questions, you don't have to memorize all the knowledge points that make you do wrong (after all, the third year of high school time is precious).
And if you have to make yourself like chemistry, it's really what motivates you.
-
Read more books to master the basics, and do more questions to find out the missing knowledge points.

If it's really bad, I hope you can read the book quietly.
Teachers and classmates must have given you a lot of methods, you have to really persevere, and the most important thing is to find the method you like.
The friend upstairs said that the method is good, find a piece of paper and write down the key equations or knowledge points.
The accumulation of bits and pieces is too important, so let's look through it from time to time, in fact, it is not difficult to memorize the basic things in chemistry.
Actually, you know the truth. Go for it!

Summary. Hello, I'm glad to answer for you, that's the case, this student, the third year of high school chemistry is very poor, return to the textbook Textbook is the basis of learning, especially poor, because the third year of high school has no time to review, so to return, the basic knowledge to master the basic knowledge of the basic score, in fact, in the face of the review of many disciplines, the current very poor, don't think about improving to a particularly high, basic and intermediate knowledge by reading notes to review the knowledge points, In addition, if conditions permit, you can find an extracurricular tutoring institution to study, which will help.
Good. Hello, I'm glad to answer for you, that's the case, this student, the third year of high school chemistry is very poor, return to the textbook Textbook is the basis of learning, especially poor, because the third year of high school has no time to review, so to return, the basic knowledge to master the basic knowledge of the basic score, in fact, in the face of the review of many disciplines, the current very poor, don't think about improving to a particularly high, basic and intermediate knowledge by reading notes to review the knowledge points, In addition, if conditions permit, you can find an extracurricular tutoring institution to study, which will help.
No, no. How bad are you?
Even now, I can only get 34 points.
Then look at your usual notes and the textbooks you have studied, and keep brushing up on the questions.
But don't do the puzzles, just do the basic and medium.
Because you're running out of time.
In addition, if you have the conditions at home, it is better to go to a cram school outside of class, because someone will explain and analyze it to you.
If I don't have time to make up for it, can I take those online classes?
Yes, too.
Because there are some things that you can't understand, someone needs to explain them.
My mentality is not very good, I don't feel very confident.
It's the third year of high school, so if you can't, just hurry up and learn, this has nothing to do with mentality.
Do you give up without faith?
This is even worse.
I think I can only make up as much as I can now.
Do your best and improve as much as you can.
But be sure to work hard.
