High School Mathematics Physics and Chemistry Stress 10, High School Mathematics Physics and Chemist

Hello, I sympathize with you, your situation is quite similar to when I first entered high school, but I didn't even understand some of the content when I first entered high school, especially math. Congratulations, you are still far away from the college entrance examination, don't worry too much!

I'm a first-year university student, studying applied physics, hehe, I just went through the college entrance examination, I hope I can help you! I'm responsible for giving you a way.

This is the most efficient and direct method I found in high school, and it is very helpful to improve my problem-solving ability and problem-solving speed. I've only been using this method since the first semester of high school, but the sooner the better.

This method can go a long way in a short period of time! Trust it!! My physics is almost a junior in high school before I succeeded in this assault, hehe.

First of all, you must learn the basic knowledge solidly and do a good job in the basic skills.

If you want to do well in these subjects, you need to complete the questions in that short time of the exam, which requires increasing the speed of solving the questions. This method may be a bit hard, but if you stick to it, you can be sure that you will be okay with the exam! This method works for every subject, believe it!!

First of all, you go to buy a synchronous set of questions (synchronous test questions), or buy a five-year college entrance examination three-year mock (this book is quite good), try to buy a set of completion times, and have detailed answers!! Buy another electronic watch with a stopwatch function, so that you can get stuck in time to do the problem.

Start doing it as soon as you follow the table, whether it's a simple question or a difficult one. If you can't do it, let it go, don't be discouraged, and see the answer later. I really don't know how to ask the teacher. And look for a sense of accomplishment in doing the questions.

But it's important to do it yourself!

After that, to the answer, to summarize. Summarize both difficult and easy questions.

Twice a week is enough, more is not necessary, and I can't stand it.

Whoever can persist in this way, he will surely see the great power of this method!

This is how I made my Physics a science and science subject, and made Math, Biology and English at the top of the class!

Let me tell you about the steps of doing a physics problem: when you do the problem, you must first visualize each process in detail (this step is quite important), and then write it out in relation to the knowledge you have learned and the relevant formulas, and find the connection between them. In the end, it is necessary to do a certain amount of questions, summarize them after doing them, and summarize them as much as possible, the more the better!

In short, remember the card time, but don't get nervous when that stopwatch jumps fast, you force yourself to think that it's not an exam. I was nervous at first, but it took a step by step to get used to it and make sure it worked!

You need to treat it with a normal mind, in fact, studying is really not just for the college entrance examination, it is also for us to increase our knowledge, from this point of study, you should be able to reduce the pressure.

Seriously, it's really tiring to study, but we need to grow, we have to add knowledge, we have to gain knowledge, so we have to learn. Don't be stressed.

Maybe you should change your mindset and think of yourself as a bad student (you used to be bad at school), and now you need to keep improving, not get good grades again. (Just a suggestion!) You can try, but be cautious!!

I'm a sophomore in high school like you. I feel the same way. The glory of the past can only be the pressure of the present.

The teacher's mind is forever stuck in the past, and that feels terrible and bad. At one point, I felt that studying science was a wrong choice. But it was never hard.

Keep at it and you'll get a good reward.

You don't need to be like this, the pressure of studying is too high, this is a matter of course, but you have to have a calm mood

One. Do you take your classes seriously?

Two. Did you do anything in school?

Three. Are you jealous up, leading to pride, learning regression.

You have to keep these three points in mind!

Grasp the essence of things, those questions are nothing more than those formulas, theorems, like physical mechanics, you grasp the force of the object in the process, step by step analysis, draw more pictures,

Don't be afraid, mathematics, physics and chemistry in high school are not so terrifying. You first try to look at the things at the beginning of each lesson in the workbook. There's a lot of ways to do questions and stuff like that.

Generally, a good workbook is very detailed. When I go to high school, there are some things that teachers may not be able to talk about. It's up to you to accumulate on your own.

After doing the question, go to the answer yourself and read the explanation. The key is the knowledge before each lesson in the workbook, which is very important.

Everything is the same, and the types of questions I have talked about are so that you can understand them thoroughly! It's important to be clear about the substance! Physics is actually not difficult to learn!

If you have more than 70 years of mathematics, it is more suitable to use "The Road to Success", and "The Case of Queen Xiongxue" is also very good. Chemistry and physics are recommended to take a look at and buy a copy of "Longmen Topics", which has a special explanation of each part of the relevant parts, which is very detailed. You can also try to buy a knowledge point manual similar to the information package, such as "High School Chemistry Inside and Outside the Classroom Knowledge First Use and Check", "High School Physics Inside and Outside the Classroom Knowledge First Use and Check", all of which are Xue Jinxing's.

The exercise book is recommended to buy the May 3 college entrance examination directly.

It is advisable to find a way to buy in-house teaching materials from top schools, as the workbooks on the market are mismatched and untargeted. And the internal materials of a good school are years of good questions.

The Venus textbook I have been using is not bad, and my score has never come down to 85, and the "Learning Master" for chemistry and biology is not bad

"Backgammon" for language

I think it is best to use two sets of "Textbook Analysis" for physics and chemistry and mathematics, one is knowledge analysis, and one set of test paper tests "Huanggang Secret Volume" is also good.

Because you still have a big problem with math. Understand more, train more.

There are some intermediate data processing in the process of solving problems in mathematics, physics and chemistry, which can omit direct osmosis to obtain data, but the main whispering formula is the basis for the process of calling hunger and your data, and you must write it on it. It's hard to explain this, but it's very good to do more questions and read the questions, and support you!!

The key is to do more questions, ask the teacher if you don't know, and you will naturally understand if you do more, you should grasp the hit rate when you do the questions, you will do 100% of the time correctly, and you will not do as many steps as possible to write as many steps as possible to get points. The time of the day should be fully utilized, and it is good to enter the state of learning, the third year of high school is very critical, and I also caught up in the third year of high school, and I scored 633 points in the college entrance examination, Shandong.

To learn, you must first have confidence, and whether you are interested or not is secondary. But that's pretty good. Have faith that you will learn well.

Don't be afraid, don't be lazy, you'll learn well. Mathematics is mainly to understand, after reading the book, understand and then do the problem, that's good, do the problem to master the method, think before doing how you think remember, the problem can be done more, but too much is not good, that will make you bored, you have to choose. It's the same thing in all subjects.

In chemistry you have to learn the connection of matter and memory, and you have to learn the system to connect the chapters with memory. It's fast and fast. Next, I am doing the problem, and the physics has to memorize the formula, and there is the content of the problem.

In particular, multiple-choice questions should be memorized.

The third year of high school is very important, as long as you work hard and can still improve a lot, in fact, the most important thing in high school is also the third year of high school, the teacher of the third year of high school will review the first and second years of high school again, which requires you to take good notes, the third year of high school to the end of the time is very tight, you can't have too much time to look at those review materials, too much, and I don't know what to look at from **, write a class of questions together, so that it is easy to review later, and there are good questions on the materials, you can cut them out and stick them in the notebook, if you copy them, it is a waste of timeIn addition, I have to do some mock questions every week, and you have to control the time, because there are many questions you will do in the college entrance examination, but there is not enough time, so you have to improve the speed of doing questions, come on, believe in yourself, and work hard!

There is no other way to learn mathematics, physics and chemistry, practice a lot, the more question types you encounter, the more you will know, remember that it is the question type, not the number of questions, a question type you are doing a hundred, then you will also have a question type, and do a hundred question types, even if you can only do 50 questions, then you are better than a person who does a hundred questions of one type. At the same time, the study of science should focus on comprehension, not rote memorization.

Let's start with the math.

The book of counting principles is more difficult to learn.,It's too abstract.,There's also probability in the same book.,It's an upgraded version of the chapter on classical generalizations that I've been exposed to in the first year of high school.,It's hard to understand.,But you can make up for it by doing more questions.,There's also linear programming.,If you think you're learning well in the first year of high school.,It should be fine.,Other functions and geometry are not very difficult.,Ellipses may get stuck on you.,There's also trigonometric functions.,Just learn well in the first year of high school.。

Physics, this subject is indeed different from person to person, I read a brief history of time and relativity before the first year of high school, although I don't understand it very well, but it is really useful, develop your brain's understanding of things (not philosophy), and spatial thinking ability, the content of the last few books of physics is a lot of content about advanced physics, that is, high school allows you to simply contact these problems, many people can't understand the essence, are just the content of the book, look at the brief history of time and the like to help you, and there is about electricity, This is the key point, the college entrance examination questions must come out, the second year of high school mainly learns the essence of electricity, electric fields and the like, and then the circuit of junior high school, upgraded to alternating current, as for the aspect of force, I have also been exposed to the first year of high school, and you think it is no problem to learn well.

Chemistry, mainly to do questions, because chemistry is not like physics, physics you can often experience around you, you can imagine, but chemistry, life is rarely contacted, the reaction equation will not be no, so you need to do questions, do more questions to get more grades can go up, understand well, oxidation, reduction, addition, substitution of these reactions, the second year of high school is mainly these reactions, more addition and polycondensation, this is the organic compounds of the book, is the focus of high school.

Biology, more liberal arts, there are a lot of books to remember, remember the questions, it's not difficult for us to go to the third year of college this year, the college entrance examination policy of Dawen Dali, just enough to answer your questions.

Normally, a liberal arts score is a few tens of points higher than a science score, and when you have similar interests or strengths, it is wiser to choose science.

Science physics requires good thinking, good spatial imagination, flexible brain, and hard work is not proportional to grades, for example, every time I take physics and listen to a small part, I start to sleep, and I still get 90 in the exam, can you say that hard work is proportional to grades?

What to choose depends on the family background, good to advocate reading, not good to insist on reading.

1.You can push it out by replacing x with 1 x, this is a substitution problem in the function, as long as the unknown quantity belongs to the defined domain, it can be substituted.

2.Who is the subscript for your log's number?

3.Substituting bx into the function, which is the square of (bx) + 2bx + a, and then using the functions of known bx to wait together to know a and b.

4.You can't write clearly.

Is the square the whole square? Your title is incomprehensible, write it clearly!

6.After the circuit is opened, there is no current in the external circuit, so the electrical appliance does not occupy the voltage, so it is equal.

7.One is to judge the electric field force, and the other is to judge the current, and I will see and make up for you.

8.How does the rectangle move, you look at the graph of it and the magnetic field, do the projection of the wire frame along the direction of the magnetic field, see that it becomes larger and smaller (area), and then it comes and goes, this inference should be known, right? Push it down a little further and it will come out.

9.The photoelectric effect is only related to the frequency of light, and the intensity of light is related to the number of photons.

According to you, it should be 3 ethylpentane, and the law still doesn't figure it out to you.

Methyl 2,4 diethylpentane.

c This is the magnitude of the coefficient, which is related to the gas conversion, and the principle of Le Chatre is clarified. a b is the coefficient.

14.Because you have a coefficient on the right side of the equal sign and a coefficient greater than the one on the left, let's figure out the principle of Le Chatre.

10.of the sum of 15

11.The principle of the longest backbone should be named 3-methylpentane, 3,3,5,5-5-methylhexane.

13.No, the g in parentheses indicates that it is a gas, and a+b>c indicates that the reaction is easy to proceed in the direction of the positive reaction, and a+b=c indicates that the reaction remains in equilibrium.

Only chemistry questions.

11.There will be no 2-ethylbutane, and the system nomenclature first selects the longest carbon chain as the main chain, so it should be 3-methylpentane.

12.2,2,4,4,5-5 methylhetane was developed first.

1. Swap x for its reciprocal. I do it by commutation.

In the first 2 math problems, the specific structure is not clear and ambiguous.

1 x is a variable, and of course 1 x is also a variable that you can replace x with a, but it's just a code 2 x x + 1 * log3 2

3 a=2 b=-3 2x-3 bring in 1 x=-1 2 or x=2 5

4 I didn't understand the question...

56 Sure, when the circuit is opened, there is no electrical appliance on the circuit, so there is no voltage distribution.7 When the magnet generates electricity, the left hand is the right hand (not sure, it may be reversed, you look at the book to make sure).

8 Same as 79 Whether the photoelectric effect is generated or not is related to the frequency of light, not the intensity of light10 11 The side chain c should be less than the backbone principle should be 3-methylbutane12 I can't understand it

13 I'm sorry . . . It's all 4 years old, and I almost forgot it.
