How do you grasp the basics of mathematics, physics, chemistry and biology?

Do simple questions, that is, the questions in the book, don't think too simple, study those questions thoroughly, there must be something that can be combined, this is to draw inferences, after doing the questions to see if there is another way, this can give you one more idea, maybe you will do a few more questions.

Don't think it's too difficult, it's not difficult, it's not difficult, see through every condition, then go to the book to find the answer, write down the formulas that may be used, and then find the rules, and then do the questions, you will find it very simple.

Do difficult and easy questions to ensure that your grades will rise a lot in a semester, but you must remember one thing, don't be careful, and look at it with your classmates.

Mathematics, physics and chemistry belong to the science category, and it is a good way to do more questions, and pay more attention to summarizing experience and learning lessons when doing questions. Most of the exams in high school are usually questions that you have done on a daily basis. In addition, the questions that you have done wrong in the past are very, very, very valuable, and I don't know if you have a record of the wrong question set.

However, there are many questions to do, and there may be a lot of wrong question sets, so it is recommended to correct them directly on the test paper, and then save the test paper (there will be many. In the last month before the college entrance examination, I was looking at the wrong questions on the test papers of the three years of high school, and I gained a lot, and you will find how simple the questions I did wrong before were.

In addition, the basis for doing a lot of questions is that your knowledge system has been established and there is no problem with the basic skills. If your foundation is not solid, then it is recommended that you take a good look at the textbook, as the saying goes, "a tall building rises from the ground", and solid basic skills are very important.

I don't know what your specific situation is?? If the basic skills are not good, it is recommended that you thoroughly understand the textbook and do the exercises after class; If you have solid basic skills, then it is recommended that you brush the questions, "5 years of college entrance examination and 3 years of simulation" is good.

The foundation is to read more textbooks, be familiar with the textbooks first, memorize the formulas and theorems in them, and remember more summaries in some reference books. In this way, you will have more ideas when doing the questions, and it is also conducive to mastering the questions.

Go and see my "", there must be a way for you to see it!

Chemistry Biology Backrest! Be sure to memorize the teacher from the first review and you can't fall behind

Mathematics and physics are certainly not bad by doing problems a few times a day, but you must understand it!!

Look at the questions more, do more questions, and focus on understanding.

Each subject has its own set of things, more summarization, and mathematics is more calculation.

Numbers themselves have no special meaning, and the so-called meanings are added in a far-fetched way for a specific purpose.

Of course, it is not useless, at least it can deepen the impression.

Chinese In the first year of junior high school, you should have time to read more, and you don't have to worry about the amount of reading in the third year of junior high school. The reading teacher will bring the practice, and some ancient texts should be kept well, and they will be used in the high school entrance examination. Essay?

will slowly improve as you read, and I'm a good example of that. The composition does not have to be beautiful, it has its own characteristics, and the description is detailed.

Mathematics If you don't learn the math olympiad in mathematics, you will suffer a lot, and you have to do more problems to make up for it.

English It is important to concentrate on word recognition, and it is important to keep up with the words. Read more, and you will have a sense of the topic in the future. The teacher must be careful in his lectures, and don't be lazy in taking notes, so that the single choice can be done well.

Politics It will be very difficult to go to junior high school at the beginning, but it will be better later, rote memorization is useless, and you must learn to steal a little laziness by summarizing. Hehe, it would be very beneficial to do more questions in liberal arts. Once, I only memorized the answers in the workbook without reviewing, and I got 98 in the exam.

Physical Chemistry Let's talk about it Let's talk about the key points of the formula, extracurricular questions are very important, and the density of physics questions is very large, and sometimes you can get the questions! Chemistry? Make up a few formulas by yourself with your own ideas, and it's easy to memorize them all.

Geography and biology are not very important, just pass the exam, but if you want to be a good student, you have to work hard, biology uses itself to remember, organs and cells, you can point to yourself, to remember. Geography, you can buy a set of maps and stick them at home, look at them when you are idle, and use your usual time to remember knowledge. (This is a skill for the 8th grade) in the first year of junior high school, common sense can meet the needs.

History should read books by yourself, do not let go of supplementary things, find connections with other knowledge while reading, and understand the meaning of not being summarized by the teacher, you must learn to summarize the language by yourself, and you can get a high score in the high school entrance examination. Important points in time can be listed.

That's all I have to say, and I have to review with you.

Mindset You will learn later that you can put your spirit on something, such as: crush on someone (only crush!) Just chat with your classmates or play some little game to make you enjoy going to class.

The language of junior high school is relatively rigid, and it comes according to the requirements.

Mathematics does some basic problem types (referring to proof questions), writes the steps separately from the calculation problems, and pays attention to the capacity check.

There are not too many bends in English grammar in junior high school, master basic grammar, memorize some commonly used sentences, and if you have time, master some phrases related to the words you have learned (which may be helpful for English reading).

Politics Open the book during the high school entrance examination, but you still have to be quite familiar with the book, you must understand the hot spots of current affairs, and it is best to combine it with the knowledge you have learned It is indispensable to do more questions If you feel that it is a waste of time to do the questions, then it is recommended to do multiple-choice questions Short-answer questions to see the main points of the answers.

Physics, several large blocks, acoustics, optics, changes in the state of matter, force, magnetism At present, the learning is very shallow, saying that there are few knowledge points, but there are a lot of tests, some small details or life phenomena, it is recommended to look at the questions after understanding the knowledge points, and remember typical examples, which may be helpful.

For chemistry, first of all, the periodic table is back to the 18th number, and the common elements must be able to write, and the relative atoms, molecular masses, etc., must be distinguished, and it can be said that among these subjects, the time spent in chemistry can be said to be the shortest, because there are not many things, memorize the reaction set phenomenon in the book, and see which test points are focused on in the test questions.

Geography, Biology, History, and Politics are about the same as Geography and Biology, and if you're interested in Geography and Biology, you can take a look at it when you graduate, and you can use it in high school.

It is good to do a good job in the basic knowledge of the language, and the composition should be written at the end

Inscription, accumulation of good sentences.

dao。You can also add points. The math formula must be memorized, and then do more answers, it is best to remember the question type, and you may encounter the original question in the future exam, so it is best to write it yourself.

Politics, history, I can do it myself, mainly by endorsement. And there must be a method for memorization, especially history, which is easy to memorize, you can memorize each other with your classmates, anyway, find a method that suits your deep memory. The best thing about English is to memorize words and phrases diligently, and of course, grammar still needs to be understood, and generally you can't get anything in the test.

Physical chemistry is mainly formulas, equations. Biogeography is not very involved in junior high school, and the final exam will be memorized in a short time, and the comprehension memory of geographical idioms is mainly to listen carefully.

When reading a book, even bai makes you dislike, also du

Listen carefully in class, write homework carefully, digest the knowledge of the day on the same day, and solve it immediately if you don't understand it, otherwise the problem will only accumulate more and more. Liberal arts things must be read a lot, extracurricular is also very important, English is more focused on the feeling, you have to read the text thoroughly, so you don't have to memorize words or anything by yourself, science is mainly to have a deep understanding of concepts, and the questions are based on those concepts, definitions, and theorems!

Preview in advance, you will easily learn each course when the teacher is in class, and solve problems you don't understand in time. It's okay to learn well.

I'm in the third year of junior high school this year, and I'll tell you that for physics and chemistry, you must memorize and write more in the front, and the main thing in the back is to understand and do more questions.

Oh, all cultural disciplines. It's natural to learn to like them first, and then learn to do well.

Listen carefully in class, ask the teacher or classmates if you don't understand, complete your homework carefully, review today's teacher's lesson when you go home, read more extracurricular books, and read knowledge.

You have to be interested in these subjects to learn them well.

The teacher said the point. I'm going to write it down in a notebook right away.

Have a positive and motivated heart. Listen to the teacher and learn from each other!

The first must be to attend classes and listen carefully. In particular, DU science zhi should practice more.

Also have an interest in these. If not.

A genus that can't be learned by any kind.

Especially English. I used to be very bad at English. It's always twenty or thirty points.

Then there was a teacher whom I liked very much. I'm still tutoring there. So I'm interested in English.

Slowly, I had no problem with my phonics. Now there is no problem with writing. I haven't scored 90 in English now. (100-point scale).

In fact, as long as you are interested, patient, and positive, it is easy to learn well.

Do more questions, study on your own, and read a lot of books.

The Honors of Rebirth on Mathematics.

In fact, I also thought it was quite rare to choose liberal arts.

I asked the teacher, and the teacher told me whatever you liked.

I don't like it either.

The teacher asked me to choose a theory.

It doesn't have anything to do with it, does it? To say that it is related, mathematics is the foundation of all subjects, as long as you need to calculate the base date.

Physicochemistry sells each other with a cross center reed.

Biology needs the basic theories of physical chemistry.

They all belong to the research category, and they need to be experimented with and practiced.

Photosynthesis and respiration in Biology Compulsory 1 The internal environment of Compulsory 3 is the focus. Physics: Forces, electromagnetic fields, Newton's laws, etc. are focused.

Mathematics: There are a lot of knowledge points, but the probability trigonometric function sequence is a scoring problem, and the basic knowledge of analytic geometry must be passed. Functions are important.

Take the points for each subject. Agree.

Physics focuses on the use of formulas, while chemistry and biology require more memorization and practice.

Hee-hee, math is my strength In fact, the most important thing in math is to do more problems, and spend 1 hour a day doing exercises. Can I give you a suggestion, I think it's best to make a correction book. Copy the questions you get wrong every time you make a book, and finally organize a type that you think is the best into a small book, so that you can quickly find the best review materials before each exam.

A lot of people think it's a waste of time, but I think so. In fact, I will make some mistakes, but at that time my thinking was not very clear, as long as I read the answer, I always patted my chest. Really, when you do something wrong the first time, the chances of making the same mistake later are great.

We can't think of answers, we have to think about what we thought in the first place. I think that only by reading more correction books and summarizing my own ideas can I reverse my wrong thinking at the beginning.

Physical chemistry, it seems that there are not many textbooks I think repetition is the best method, of course, I have to summarize I read it in the second middle school, and the method there is really good Spend some time on synthesis every day, and insist on spending half an hour on physical chemistry every day If you are a freshman in high school, then congratulations, because you are much luckier than me The road is out, and I have tried many methods, maybe this is also the best (personally think) I wish you to inherit my hope, I am only admitted to the undergraduate degree, may you be admitted to the double book 2005-09-01 13:32 I wish it would be as you say.

Mathematics is the foundation, physics and biology are extensions, and chemistry is the end (I used to read some famous books that were proposed by experts); I hope to solve your doubts, I wish you a better level in your studies, I hope to adopt, thank you!

Mathematics, physics, and chemistry are the "brothers".
