Current location - Training Enrollment Network - Mathematics courses - I can't continue my science and math grades. What should I do, ask for help?
I can't continue my science and math grades. What should I do, ask for help?
Obviously, the foundation is good, but every time I manage it, I can't get good results. There seems to be a bottleneck I can't break through. Presumably, many small partners are distressed by this. How can we solve this dilemma and get rid of the situation of good grades? Let's look at the analysis!

After every big exam, those students who always feel that they have a good foundation and have not achieved ideal results are the most depressed. They may find that when they reach a certain height, it is difficult for them to achieve higher results. They always make many unexpected mistakes in exams. In reality, there are not a few students in this situation. Some students haven't figured out what they failed in the college entrance examination, while others have found various reasons to explain it, such as nervousness, clerical errors, miscalculation and so on. For the college entrance examination, your test score is not high, and all the reasons and excuses are pale and powerless.

In front-line teaching, we have studied many problems, and the above problems are very common. Let's analyze it together:

The scores of candidates with this situation are generally between 200 and 230 (comprehensive). The external performance of these students can be summarized as follows:

1. People around you (including parents, teachers and yourself) admit that you are "smart", but you just can't get high marks in the exam.

Both Chinese and English have no advantages. I feel that I don't have the so-called "liberal arts thinking" but have "science thinking", but it is difficult to get high marks. I seem to have done well in the comprehensive science exam, but the disadvantages of Chinese and English put me at a disadvantage.

I have done a lot of papers, and I have been working hard, and my homework has been finished on time. However, my comprehensive score has not reached a certain height, and some students even doubt themselves. This situation is a common phenomenon for some girls whose grades are above average. In addition, after several exams, some people complained about choosing science.

The above three situations are common phenomena among candidates. What is the specific reason? Why can't their comprehensive scores reach a higher level? The following is a detailed analysis, explanation and some suggestions. I hope I can give you some reference:

First, the key points of training were not grasped.

Many students didn't make progress and did a lot of problems, but some crucial things were ignored by them. No one explained the truth to them clearly, so it was difficult for them to find out, so they wouldn't make progress.

Let's look at a specific theme:

For example, chemistry:

When these students deduct points, their points are rarely deducted because they can't do it, not because the topic itself is difficult, but because of their negligence. Multiple-choice questions are occasionally deducted, and there are two main reasons why multiple-choice questions are occasionally deducted. One is to take it for granted and fall into the trap, such as Haidian Zero Mode 12, and the other is that the exam status is not good and the mistakes are unclear. If a student makes one or two wrong choices, the last finale will be deducted, which will directly lead to the basic reimbursement of chemistry. They will be the last finale as a whole, but a little deduction here and a little deduction there will add up to much more deductions. After the papers were handed out, I always felt a lot of regrets. Also, I always feel that my ability is not much different from that of the excellent students around you, because occasionally you work out the problems they didn't work out, but ...

In reality, there is no if. In reality, especially for students in Beijing, you got 95 points in chemistry in many exams. In some schools, some classes may not even get the average score. Therefore, for students with a good foundation, if the chemistry test scores about 90 points, the subject will be "scrapped". Such a reality, but how to train to avoid it?

Because students want to get good grades in chemistry exams, they must make the comprehensive questions of basic theories fluent and pursue perfection in training. Why do you want to do basic theory synthesis questions? Through training this link, we continue to analyze together:

1. Lay a solid foundation

The comprehensive questions of basic chemical theories are dominant in both Beijing and national papers. The four finale questions in Beijing Volume, including experimental questions, are almost all based on basic theories except relatively independent organic chemistry. Of course, some students want to ask, what is the basic theory? Let's give you a brief summary:

The so-called basic theory is this:

(1) redox reaction

(2) The application of Goose's law in calculating the energy change in the reaction process.

(3) The topic of electrochemistry is related to electrolytic cells and primary cells.

(4) chemical reaction rate and chemical equilibrium

(5) Problems related to ion balance and equilibrium constant in solution.

It is not only the finale that concentrates the above contents, but also the multiple-choice questions. Taking the 20 13 Beijing College Entrance Examination as an example, the above contents of seven multiple-choice questions account for six. If students have been specially trained in the above comprehensive questions, they will have great advantages in the coverage of questions and knowledge points. For example, the basic part of electrochemistry, the college entrance examination is almost all around these aspects: the principle of primary battery, new battery, electrolytic cell, metal protection and corrosion, and comprehensive investigation of electrochemical knowledge.

2. How to improve performance through comprehensive training?

If you do four (random) basic theory synthesis questions in a row and get them all right, then your score level is definitely at a high level, and you can keep it as long as you keep training. Their biggest problem: a student who has done a lot of questions a year but has no quality can easily be deducted from the exam.

(1) Strengthen your own requirements. Since getting 95 points in chemistry sometimes may not have an advantage, we should ask ourselves to get full marks in training and try our best to grasp them in training.

(2) Shortcomings in training should be summarized and solved in time. If there are loopholes in the knowledge points found in the training, we should immediately make plans to make up these knowledge and study how to use it. If you have shortcomings in the process of expression, you should study expression seriously and make the greatest improvement in training.

(3) Training is not a form, but an end. Some students study machinery, especially those who don't like to think. They heard that training with basic theory comprehensive questions all day is helpful to improve their chemistry scores, so they asked what to do. In fact, this attitude is not enough to improve your grades, because you don't understand, why do you need to train? What is the ultimate goal of training? And said that training will definitely achieve the goal, but if you want to achieve all the right goals, you must train.

This is what many chemistry students lack. Without such training, it is difficult to improve your grades quickly.

Second, study and examination are an organic whole.

Return to the basics, textbooks and outlines, but for many students, these are empty words, because it is difficult for students to operate in practice, even for students with excellent grades, it is difficult to implement them. Let's take biology for example. A student thinks that he knows all the basic knowledge in the book, but he can't get high marks in the exam. He thinks that there are many biological knowledge points and the questions are scattered irregularly. They asked how to adjust the problem. Or what other specific practices are there? However, in order to reach a certain level of biological score, several important links must be done well. Without them, your grades are also difficult to improve.

1. Turn knowledge points into test sites.

It is not enough for candidates to understand only the knowledge points. They must know how to test in the exam, which is the key to score quickly. For example:

You may have a good grasp of the basic knowledge of cell life course, but there is no induction in the question. Here is a brief summary: The following statements about the life course of cells are correct:

(1) Vicia faba root tip cells completed a cell cycle in the medium containing tritium labeled thymidine, and then continued to divide into metaphase in the medium without radioactive labeling. The distribution of chromosome radioactive markers is that each chromosome only marks one monomer.

(2) Cancer cells, like embryonic cells, are divorced from normal cell differentiation.

(3) Spindle and centrosome can be observed in animal cells during mitosis.

(4) During the process of wheat pollen culture in vitro to form haploid plants, cells differentiated, which can reflect the totipotency of cells.

(5) Cell senescence is characterized by decreased enzyme activity and decreased nuclear volume.

(6) The main function of proto-oncogene is to prevent abnormal cell proliferation.

Look at the above content, just the knowledge of cell life course can contact so many test sites, but everything has changed since its original religion. If you don't know what has changed and what hasn't, and just stay in the memory of knowledge points, then your grades will definitely be difficult to come up.

2. Lack of main line in preparation.

Many students ask what is the main line. In fact, for biology, many keywords can be used as the main line, such as conditions, structures, functions and so on. Taking conditions as an example, we can connect a lot of knowledge in series, such as the content related to enzymes, PH range is the condition, temperature is the condition, and concentration is the condition; About this part of the knowledge of photosynthesis, what conditions should light reaction have, and so on; What are the conditions for information to spread between nerve cells? What conditions do the materials meet in the experiment, what conditions do other environments meet, and so on? Looking at the main line, it is easy to become a higher angle and a more overall preparation. There is not much biological knowledge itself, and it is not broken, but you have not built the main line.

In fact, as long as candidates pay attention to contact when doing the questions, on the basis of distinguishing which are the key knowledge, look at how the materials and knowledge points are combined when doing the questions, what is the purpose of the examination, and what are the characteristics of the interference items. These are all very clear. What gains, rules and shortcomings have you found after completing the questions? These are efficient preparation for the exam.

Third, answering questions by feeling is unreasonable.

Many students answer questions by feeling in the exam. When they feel good, they can get more points. When they feel bad, it is difficult to do well in the exam. Then, after a model, we suggest that students carefully compare the standard answers to see where the gap between your expression ideas and your answers is, what is the difference between your answer logic system and your answers, especially the step expression, what content is missing and so on. These are all things that need to be faced, and of course they are also an attitude and accomplishment.

When analyzing these students' papers, I found that most of them only wrote formulas and final scores. Although these are all points, strictly speaking, there are countless reasons for giving points. For example, in your formula, there are no letters that even appear in a question, and there are no conditions to tell people. Or when you do sports questions, you don't say which direction is right, so you just come up with a formula and write numbers. Therefore, for many students, it is not that they failed in the exam, but that they failed to reach the standard of high marks in training.

Although these students have other shortcomings, we have time to write relevant articles and study together, but the above aspects must attract the attention of relevant students. After all, they all come from practical experience, and many students have improved their grades greatly.

How to rush from 100 to 285?

1 the holistic view of science comprehensive learning

For many senior three students, first of all, they should be familiar with the mode of comprehensive management. Regarding the order of comprehensive management, I specifically asked the teacher, and she said that 90% of the students with excellent grades are in the normal order, that is, physics-chemistry-biology. Such is also the case with me. I was a little uncomfortable at first, but I found it a skill to get high marks in physics! If the students still can't get 100 in physics, it is suggested that they do their best subjects first, then do the second best, and finally do the least. My own order just now was for students with a comprehensive score of 250+.

2 About physics

First of all, everyone must remember that as long as you are good at physics and mathematics, you will definitely be the champion of the college entrance examination! Physics is divided into three modules-exam selection, experiment and big questions. Many students didn't get high marks in physics because they didn't choose the right one, so did I. Generally, they will make 3-4 mistakes in physics. However, the knowledge points involved in the examination are relatively wide, the study time is also relatively long, and the results have not improved much.

● Experimental questions

I found a breakthrough in the next semester of senior three, that is, to overcome the experimental problems first! Overcoming experimental problems is like English grammar &; The basis is the same. If this is good, you will find that the rest things are easy to improve, and the knowledge points of the experiment are very specific. (For example, the first question will be the experiment of Newton's three laws, and the second question will be the calculation of resistance. The experiment of Newton's three laws can make you remember the knowledge of Newton's laws in your heart, while the electrical problem can make you remember the basic knowledge related to electricity. It is simple and moderately difficult, which is very easy for students with poor foundation to go to school. At the same time, empty calculation will cultivate everyone's accuracy and computing ability.

I suggest you do, test research, experimental topics, the book is small and thin, I read it in about two weeks, but it took four weeks to summarize it. The difficulty is the level of the college entrance examination, which is completely close to the exam. It may not be suitable to start because the experimental questions are comprehensive. But do it for a week and you will find that you can successfully complete a big problem.

This book is enough to make your experiment a mistake of about 3 points, but only if you learn to summarize! Summarize what?

1. Theorem and formula (Niu San and its deformation, Ohm's law, etc. ) When it comes to electromechanical templates, you have to summarize them by answering and analyzing, which is what you have to recite.

2. There are many ways to explore mechanics. What forms do you want to sum up (whether the board is inclined, whether the control variable is weight or inclination, whether the car's own quality factor is considered, and whether it is a free fall experiment). These are all things that you need to sum up carefully. You need a brain full of materials without that clever brain, so that you can think of how to solve this problem when you encounter familiar inquiry forms and questions.

3. Electricity is based on theorems, supplemented by calculation. You also need to summarize what kind of problems you have. Theorem: spiral positioner, vernier caliper, how to measure. This is all memorized. Common test types: measuring resistance (fixed value &; Semiconductor), modify the instrument. The types of questions usually include:

(1) Draw a circuit diagram: This requires you to do the problem and draw a common circuit. At the same time, you need to judge the internal connection and external connection, and there are many methods. These are explained in detail in the commonly used exercise books. Senior just gave you a concrete outline of how to summarize, and you can practice it according to my outline.

(2) Research coordinate judgment resistance/power supply internal resistance /G meter internal resistance and electromotive force. This requires observing the abscissa and ordinate, origin, intersection, intersection of extension lines and so on. Looking for the law of reading pictures in the process of constantly doing problems.

calculate

It is the easiest to do the examination of electrical experiments, but it requires a lot of calculation. At the beginning, everyone would take a lot of detours when doing the problem, and they couldn't get the answer after calculating a lot of numbers. That's why senior sister suggested to investigate the test questions. You need to carefully study the solution in the examination questions-solving the binary linear equation and ignoring the minimum resistance when the number is maximum ... There are many other methods, but what I said is only the most common one.

You compare these methods and find that many of them are * * *, and then summarize them. Exercise your calculation ability and accuracy by constantly doing problems and reflecting. Attention! Even if you find the rule of experience, you won't get full marks easily. Don't pursue perfection. Deduct 3 points is ideal! When you use this book as I say, you must sum it up! After summing up, you will find that your physical choices and big questions have been greatly improved! In fact, as long as you are proficient in one section, the ability of other sections will also improve, and the results will also rise. But the bigger questions and choices in the experiment are the easiest to get started.

● Multiple choice questions

First of all, you need to have a comprehensive knowledge base! ! (For students with poor knowledge points, the questions are useless), then learn skills (exclusion, limit, introduction, division, isolation), and then overcome multiple-choice questions. After the experiment, you will find an overall improvement, which varies from person to person:

1. Students with poor foundation must recite the first and second formulas of physics first! Start doing physics exercise books, and the school can review them in one round. There must be a classification of knowledge points and questions, and don't do the questions blindly.

2. Students with a good foundation can make six choices in physics.

The same thing is to prepare a piece of paper and write down mechanics, electricity, magnetism, elective courses, etc.-the more detailed the better. Tick the right number on it according to the wrong questions, so that you can know where your weaknesses are, and then choose a topic to specialize in. I choose to do it early, middle and late every day to accumulate knowledge and enrich my skills. In this way, the original 3-4 channels have become 2.5 channels, which is very stable (my biochemical radio station has never deducted points).

● Knowledge points and promotion questions of multiple-choice questions.

Knowledge points are like judging the history of physics. Which of the following options is correct ... about three questions, and the rest are promotion questions. For most ordinary students, this time depends on asking questions and summing up. It is recommended to buy special exercises.

Electricity is often based on capacitor plate change, particle movement in magnetic field, particle movement in electric field, electric field/magnetic field distribution diagram, circuit sliding rheostat change, internal and external electromotive force/internal resistance of power supply. ...

Mechanics is based on the force analysis of objects, the movement and force of the slider on the conveyor belt, the calculation of acceleration/force, the force and speed in the process of circular/flat throwing, the problem of two objects chasing and meeting, and the balls at different extreme points of pipes/ropes ... Different methods (exclusion method, limit method, introduction method, whole method and isolation method) are needed to solve different problems.

Although the multiple-choice question is more complicated, you will have an outline in your mind after summing it up. Summarize these types in your own exercises and then list these solutions in this book. If you continue to summarize, you will find that your thinking is very clear!

At the same time, you should pay attention that even if you make more summaries and memorize more knowledge points, you won't make all the choices right. Every time you keep an error of about one and a half in physics, it is a very good score! It has been like this since the later period, no matter what kind of questions will be like this. This is normal. Don't pursue perfection, learn to choose.

● Big problems

For big questions, physics, like mathematics, is very distinct. The first is mechanics, and the second is electricity. But the strategy varies from person to person: if you are relatively good at mechanics, try to finish the mechanical problems, and if you are good at electricity, try to finish the electrical problems. The first step and the second step are relatively easy, but different people have different degrees of mastery of force/electricity.

At this time or to sum up:

Mechanics: chasing and meeting problems, plate problems, small ball tube+flat throwing multi-process problems, conveyor belt problems, friction free falling problems. ...

Electricity/magnetism: The ball moves in an electromagnetic field.

There are various mechanical forms, so it is recommended to be familiar with the plate problem, which has always been a hot spot here. The problem of plates has always been a place that everyone can't understand. Because it has to study many processes. At this time, it is necessary to think in doing the problem:

What is the starting point of this problem-using the holistic method/isolation method (usually the first question)?

There are many processes in this problem, and what is the analysis order? This needs to be summarized in the problem. After doing a certain plate problem well, the common starting point and analysis order will be summarized.

What method/physics is used for this problem-most of them are isolated whole, but there are kinetic energy theorems and conservation of mechanical energy.

What physical model is used for this problem-flat throwing, circular motion of pipes and ropes, respective motion of elementary particles in capacitors/magnetic fields/electric fields, motion of celestial bodies, gravity-like action and motion between charges ...

Electricity: Compared with mechanics, electricity is very simple-the ball moves in the electromagnetic field (coordinate axis, pipeline, flat plate, cathode fluorescent lamp screen ...), but the method of solving the problem is very simple, usually the first question is very simple. For the coordinate axis, it is necessary to accumulate various motion trajectories. For pipes and plates, we must first strengthen our own mechanical and stress analysis (integral isolation method) and skillfully use it, so that we can see the breakthrough point at a glance.

The fluorescent screen (electron tube) is two straight lines+a flat throw. The solution is to use kinetic energy theorem to accelerate the board, change the angle of flat throwing, and finally hit the screen in a straight line. This kind of problem needs to recite the problem-solving method in the exercise book, which is very common and skilled, that is, it needs to constantly exercise the calculation ability.

Physics has simply completed the strategy and knowledge outline of high school. However, I want to make it clear first that my senior's worst score is 590/600, but there is no problem with the original knowledge, just a student who doesn't know how to learn it. Students whose level is too poor should consider their own situation. I think 500+ is applicable. And 200-400 students suggest that you practice the foundation! Recite the basic knowledge points! Read through every lesson!

3 About chemistry

I think the only way to improve chemistry is to summarize. You have to understand what it often tests, and then practice and solve problems skillfully!

Mathematics requires you to be familiar with the general problem-solving steps of various types of questions, English requires you to have a solid foundation, Chinese requires you to have a strong understanding, physics requires you to master skills, biology requires you to remember knowledge points, and chemistry requires you to make enough summaries of questions.

So how to use a round of review books? -put the wrong questions together in a special way.

● Fill in the blanks

Fill in the blanks with basic knowledge: there will be blanks in the book and you don't need to memorize them. You just need to copy the answers according to the books you bought at school or yourself, and then tick out some unfamiliar places with a red pen and write them down in your notebook. I don't need to recite what I originally understood, the focus is on unfamiliar places!

Low problem type (choice)

You must do the problem. The characteristic of chemistry is that all kinds of exotic elements are introduced by the knowledge you have learned, and then the nature is inferred, so you must do enough questions (more than physics and biology). In every chapter, you will encounter some very unskilled problems. Generally, most of them are calculation problems. At this time, you can cut them out or copy them into your notebook and study the analysis method carefully.

For example:

My hydrolysis balance is very poor. I can't see the problems clearly when I see the hydrolysis of acetic acid and bicarbonate, so I cut all the problems I see into my notebook and analyze them one by one. Finally, I found that no matter what acid radical it is, it uses an electron conservation, a proton conservation and a substance conservation, so when I do the next question, I will first distinguish what conservation is, and then push it again to see what is different from the option. After summing up this rule, I did many more questions, so I became more proficient.

For example, mixing CO2 and O2 into Na2O2 and Na2O, and asking about the mixing ratio and weight, I picked out these problems from a round of review books and put them together, and found that the research methods are nothing more than difference method, limit method and other ideas. You can overcome them by skilled problem-solving methods only by changing the substance or quality, but this requires you to study various analytical methods.

The examples in this round of books will not be complete, but they will let you know what kind of questions you are poor, so you need to search for questions again. It's more convenient to find it online, and there won't be many special books.

3. big questions: big questions are a very comprehensive question type. Senior sister suggested focusing on these categories: inference questions, chemical (hydrolysis) equilibrium questions, electrolytic (fuel) batteries, experiments (organic &; Inorganic). This is the most common question type in the college entrance examination, and these questions will also be designed in the general examination. Everyone is concerned about these big problems.

I suggest you put the college entrance examination questions in recent years &; University simulation questions are divided into the above categories and put together. After doing it, you will be familiar with what questions you often ask: for example, experiments will ask you about equipment, inference will ask you the most basic questions, fuel will ask you about materials, and you will have the opportunity to ask you about impurities ... There are many chemistry questions, but when you put them together, you will find that there are only a few questions in the exam. At this time, you have to analyze how to do these questions.

4 About biology

Biology is a very good subject to be promoted, and the genetic abuse will be about 70 points next semester (100 out of 100). However, the second year of high school frantically practiced the exercise book of compulsory three, and the knowledge points were memorized by rote. The third year of high school scored about 80 points (90 points out), indicating that the judgment of biology in college entrance examination is largely based on basic knowledge, rather than the calculation of troublesome genetic problems.

● Textbooks

So no matter whether you study well or not, you must study biology textbooks seriously. Maybe you were bombarded with biology exercises in a round of review. Next semester, you will find that all the students have thrown away their exercise books, and everyone is carrying a compulsory biology book everywhere.

So how to use biology textbooks now? Senior, let's sum up the methods.

Whenever you see a question (with multiple choices), please carefully find out the keywords in the four options after you finish. Sometimes you only take one knowledge point in the exam. Whether it is right or not, you should open the book, find this page, and see how the knowledge points asked in this question are said in the book.

You don't need to read the whole chapter. Many options involve the length of several sentences. Look at these.

You may ask, how troublesome is it to turn over so many biology questions one by one according to the textbook?

I did the same thing at first, but after doing the questions for a few days and turning over the books for dozens of times, I will find that many places will be repeated, which I am already familiar with in the books. If we meet again at this time, there is no need for you to see it here again.

If you encounter the pages and chapters involved in the topic for the first time, you must practice. Over time, you will be quite familiar with the knowledge point, and even test whether this knowledge point can be related to related issues. The combination of topics is much better than memorizing knowledge points!

This will give you an absolute advantage in reading in the third year of senior high school-you can review your weak subjects while other students stay up late reading biology textbooks.

● Workbook

It is suggested that senior three students buy a knowledge booklet, which is as big as the palm of their hands for math and science students. It's much more convenient to check than classmates! It is also convenient for you to recite the most basic and important knowledge points without requiring more knowledge points. Any brochure is almost the same, just buy one. It is recommended to use a round of review books issued by the school for the big workbook, and the questions are enough for you to do!

About the types of problems

● Choose the third year of high school to start next semester, which is suitable for special practice. Only by reading books to consolidate knowledge points can we strengthen our choices. There is no one who doesn't read books and doesn't master knowledge points. Well done!

For the future, it is suggested that students who want to improve in an all-round way do 45 sets of biology (not comprehensive science biology), which are simulation questions of famous universities in various provinces and cities. High quality, many questions, and sufficient knowledge. You can improve your score by doing problems.

● Big problems

At the end of senior three, my knowledge was relatively comprehensive, so I opened 45 sets of comprehensive theories, which were selected from big topics-photosynthesis/respiration, heredity, filariasis/meiosis, homeostasis (hormones, nerves, immunity), biological experiments, and K value of ecological environment growth. ...

Specific to these categories, I will choose a certain time to specialize in a certain category after classification, and achieve a certain number (about 10+), so I will summarize them together. What should I summarize?

1. What is this type of required question? For example, photosynthetic respiration must be combined with images to ask where C3 and O2…… are produced. ...

2. What are some slightly more difficult questions? For example, the last two problems of heredity, error analysis of experimental research. ...

3. What is the most basic knowledge of this kind of exam? . For example, photosynthesis/respiration is the process of CO2 and O2 generation, filamentous/meiosis is the basic change image, and hormones are the three models in the book (thyroid, antidiuretic, insulin). How to control the independent variables in the laboratory ...

Although I summed it up, my brothers and sisters still have to start small branches according to these and start a big problem of the system themselves. Many big questions are fixed basic questions every year, so pay attention to get the most basic score, analyze from shallow to deep, and then get high scores.

Elective course: you need to memorize, and you have no skills at all! The exam is to make you recite and fill in the blanks like reciting ancient poems, but at the same time you need to master flexibly how to combine the answers skillfully.

3. Wrong title

Let's talk about the wrong problem book first. Many students asked me if I should make a wrong exercise book for math and science students, because there were too many exercises in one round of review. As far as three years' experience in senior high school is concerned, the wrong questions are completely different from person to person. Take our junior high school as an example. Senior three student Z, senior three student X and senior three student I, our college entrance examination results are almost the same.

Z, a senior three student, never finished the problem, and began to cut all kinds of papers with a knife. She never did extra-curricular exercises, and almost all the papers issued by the school were done, but she did not miss a set, posted it on the wrong book, and asked the teacher questions with the wrong book until the last moment of senior three.

In my senior year and senior year, I will choose to do some school problems (I don't want to try, because I missed a lot of knowledge points for a while), and at the same time, I will do extra-curricular exercise books, with a little more questions, but this lasted for about two weeks, and I think it took me less time to do the wrong exercise books, so I stopped doing a lot of wrong exercise books and only took a book as a summary in the last 30 days of senior year. There is nothing wrong.

Xue Ge X likes basketball, and he is not a dumb boy studying in the arts. He only does school exercises, but he concentrates on his exercise book and never makes mistakes. In the end, our three grades were probably 1, but using the wrong books was completely different. So I suggest you try it for two months to see if it suits you.

But don't give up the wrong book because you are lazy, or you will spend the rest of the exercises on this time! All right! That's all. Finally, I wish everyone can finally realize what they want. Come on!
