Cram students have poor chemistry and only have a little foundation, but they are also very zero, ho

I don't know if you're a junior or high school student. In your case, it is estimated that you will not be able to read very well on your own, and I also recommend that you hire a tutor. If you encounter specific problems during your studies, you can also join me if you wish**.

Do questions, see those who don't know how to do in the book to find the answer, so it is a shortcut, you can also start reading the books in junior high school, find a way to understand what you don't understand, memorize experimental phenomena, analyze the causes of phenomena to deepen your understanding, and write more chemical equations

The periodic table is a key point, and the second is to memorize the equations and then do more problems to cultivate feelings.

Read the information book, do the questions, ask the teachers and classmates if you don't know, prepare a collection of wrong questions, change it and do it, do "5 years college entrance examination 3 years simulation" I think this is good.

Do more exercises, do more experiments, read more reference books, and memorize more formulas. But the most important thing is to make it your hobby!

Depending on your specific situation. Generally, it is rare for outstanding students to make mistakes in the question, so no matter what the current results are, we must grasp the foundation and grasp it firmly. Then train according to the test center.

Saved, I'm a science student. Tell you some of the most important content, as well as tips.

Two sets of conclusions on the periodic rate of the elements, atomic number, radius, metallicity and non-metallic, melting and boiling point ramp law.

The key to leveling a redox reaction is to find the right reference, i.e., the part of the element that changes.

Multi-step calculations, using conservation of elements and conservation of charge, using the proportional relationship between elements, can save time writing equations.

Organic chemistry remembers the characteristic reactions of functional groups.

Remember the examples you have written, have the question type in your head, don't need to study new questions, focus on review.

Learning takes skill! It's not rote memorization.

Read more examples in the book, get the basics in the textbook thoroughly, and then do some exercises, not too difficult.

Let's just say that you want to review it yourself first, digest and absorb the content he taught last time, so that it is better to master, how about it?

My mom signed me up for a class, but I couldn't come.

There should be, there was a four-year break in the next class in junior high school, everyone was thirteen or fourteen years old at the time, she was seventeen, and she should be twenty-one or two in the third year of high school.

Take a good look at the books you have learned before, buy a little book about the basics to do, this must lay a good foundation, otherwise, your blind tutoring will also have no effect, or you can find a teacher for one-on-one tutoring, which should be of great help to you.

The chemical regularity is quite strong.

If you understand a question, you will be able to understand the rest of it.

Tutoring is not as good as reading books on your own. I can read seven or eight changes in chemistry books, and I take the college entrance examination science comprehensive 273.

The most important thing for you at the moment is the mentality, if you don't understand, ask him, a good teacher will not bother the student, it is recommended to start with textbook exercises, God rewards hard work.

It is still necessary to lay a good foundation, take out all the books of junior high school and high school, and look at the basic knowledge, definitions, properties of substances, colors of compounds, various reactions and conditional phenomena, etc., these will be done, and then do the questions to expand the thinking. (If possible, it is best to do the experiments in the book by hand, so that the impression will be more profound.) Otherwise, it's like going to a cram school for tutoring if you don't know words in English, and the effect won't be very good.

If you want to be effective in a short time, it is recommended to start reading the review book directly, buy a reference book with a knowledge context, it is best to be thinner, too thick to read and blow confidence, carefully browse the context to know what to learn to have a direction. Then go through the reference books, and know what each knowledge point roughly means and which chapter it is in. Then I started to do mock questions and real questions directly, and the first five sets were done by looking at the book, and I did it hard, and if I didn't know it, I went to the book to find it, and the role of the previous step was reflected here.

With the experience of five sets of questions, start to summarize, and the recurring test points must be important, so that you can have a rough idea of what to test in the exam, and start to review in a targeted manner. Finally, the questions should be closed in the book, and the wrong questions should be sorted out in time, so as to know why they are wrong, or they will be done in vain. After all, this is a castle in the air, and the foundation is definitely not as solid as learning well, but it can definitely be done seriously and raising the results to the public level.

Poor basic knowledge.

It is necessary to systematically summarize the basics.

Combined with exercises, brush the questions repeatedly.

If I don't teach you the method, you will say that you will be able to learn the most basic chemistry, and it will be impossible to score less than 50 points, the periodic table of chemical elements, common elements of inorganic compounds, valence, atomic weight, have you memorized them? Common substance forms, the name of the corresponding substance is commonly known as remember. If you don't know any of this, you can't study well, you're in your third year of high school, you don't seem to have much interest in chemistry like this, I don't have to memorize it when I go to school, I remember it.

The whole comprehensive paper is about 200 points.

Give it up, or do it according to which one of the following says.

It is impossible to increase by a few tens in half a year.

Or prepare to repeat a year.

Back to basics, 100 points in chemistry in the college entrance examination, of which 80 points are basic and 20 points are difficult questions.

Summarize in a timely manner and systematically summarize high school knowledge.

Pay attention to the wrong questions and study them repeatedly.

Brushing questions is also essential.

Adjust your mindset and believe that you can.
