Many candidates failed because of mentality problems, and students in World War II faced more tests than those in World War I. ..

World War II does not mean that World War I will repeat itself. We need to adjust our mentality and stabilize our mentality!

Is it painful to take the postgraduate entrance examination in World War II? Pain. However, there were many people in World War III and World War IV. Stagnation, there will always be people who will face difficulties.

Only by believing in yourself, overcoming hardships and facing difficulties can you get out of despair after the failure of the postgraduate entrance examination in World War II!

To talk about the despair after the defeat of World War I, the answer is not despair, but the momentary loss after the results are announced, which has caused fear for the future.

At that time, I thought a lot, because I have experience in stock trading, so I said that my psychological endurance is still quite strong.

During that time, I thought a lot of things myself, and sometimes I thought about the stock chart. Do you know what the most beautiful stock chart looks like?

Some people say that it goes up every day, but the old saying tells us: no, it's too late.

Dialectics tells us that the development of things is spiraling.

So the near-perfect realistic stock chart is like this:

Chart of Contemporary Ampere Technology Co., Ltd., the world's largest power battery manufacturer, from 2020 to 2022.

Later, I learned that no matter what I do, the probability of smooth sailing is even greater. The ups and downs of life are the norm!

It is normal to feel desperate after failing in the postgraduate entrance examination. After working hard for a year, I finally failed to win the fruit. How can I not despair?

Not all efforts will be rewarded, but efforts will be rewarded. Postgraduate entrance examination is like a battle without smoke, and winning or losing is a common occurrence for military strategists.

Failure in World War I is not terrible, and the probability of landing in World War II will be even greater. Candidates in World War II not only have a foundation, but also have a clearer goal and are more serious in postgraduate study!

Knowing this, I know that the postgraduate entrance examination in World War II is not just a process of climbing up again after a short trough. I hope everyone will adjust their state, get out of this defeat and continue to climb the peak.

After all, the process of climbing to the top is more memorable than the process of reaching the top.

Chicken soup is over here. Let's talk about some thoughts and summaries after World War II. I hope to bring some help to everyone.

1. Get out of the shadow of failure

Looking back now, my review of World War I was unsystematic and disorganized, which determined that it was doomed to failure.

Fortunately, during World War II, I seriously reflected on the problems of World War I, and finally started the review of World War II in a good state.

World War II is a very painful memory for me, because the uncertainty of the epidemic and various things around me repeatedly harassed me, but fortunately, I finally finished the exam as I hoped.

At the beginning of World War II, because most knowledge points were learned in the first year, we didn't review the basic knowledge and started directly from the topic. At that time, I used a brush platform for postgraduate mathematics, so I knew I could do it.

I use this platform almost all the time, and then match it with real questions and some exercise books, as well as some simulation questions.

In the process of applying knowledge, the influence of my defeat in world war I mathematics is also disappearing little by little.

Of the four subjects in World War I, mathematics was the worst one I got in the exam, so since I planned to start World War II, mathematics has been my biggest concern, and my fear of mathematics has been haunting me.

At that time, I was 22 years old and had just finished graduate school, so I brushed this platform on Zhihu. I remember it clearly, because the holiday is coming, and I need to do a nucleic acid before I go home.

Zhihu was painted when I lined up to do nucleic acid. Because I still have some feelings about mathematics just a few days after the exam, I lined up to start writing questions. At first, I was mentally calculating the limit part of the first chapter. At first, it was relatively simple. I worked out a few questions and wrote them correctly, but I didn't study any more because I was distracted by other things.

Later, after I officially started preparing for the exam, I reflected on the reasons why I didn't brush the questions in the first year. Considering the function of knowing how to brush the questions, I went directly to buy and do it.

I wrote three chapters at first, and I kept brushing until I couldn't move. At this time, I will continue to push forward and then ensure the comprehensive test every day. After finishing advanced mathematics, I wrote the basic article of 1800 (I didn't do it because I didn't think the previous article of 1800 had much significance) to test my mastery ability, and the correct rate was ok, generally around 90%.

At this time, my fear of mathematics was greatly reduced. Because I know that as long as I continue to brush the questions on knowing and doing, mathematics will not hold me back.

2. Find problems and solve them

After using it for a while, I finally found that my poor math performance in World War I last year was also related to my learning methods.

Although I was able to master the examples in books during World War I, I began to scratch my head as soon as I met the problems in after-school exercises and exercise books.

There is a saying that what you see is not necessarily what you see. This is the exercise. You can't do exercises. At this time, you turn over the answers. After seeing the answer, you think you can. In fact, you don't really have it. You just have to remember the answer.

Exam-oriented mathematics is the training of problem-solving thinking. It is precisely because of this lack of thinking that I failed to a certain extent in the first year of preparing for the exam.

In addition, in recent years, the postgraduate mathematics has strengthened the investigation of the amount of calculation. This is also the place where I usually don't practice enough.

In the process of using Zhihu, Zhihu almost solved these pain points for me.

Let's talk about the wonderful use of the unity of knowing and doing from these two aspects:

(1) Knowledge points are digested in blocks.

The sea tactics have always been a panacea for improving exam results.

However, I don't think the tactics of asking questions about the sea is the most effective way to improve math scores, but we should aim at ourselves to improve our ability to master knowledge. Know that you can do this, then give an example. Post some questions below:

1. The sum differential product formula is slightly integrated, which is commonly used as the topic of integral formula.

The above is a mixture of two or three knowledge points, such as simplifying the formula first and merging 1. You need to use the formula after calculating to 1/(cosx-sinx). If you are not familiar with the formula because of the weak foundation, the following (cosx-sinx) cannot be simplified, so you can't do this problem, because it is more troublesome to add and subtract the integral in the shape of 1/ sine and cosine. For example, please try the following link:

The process of solving the problem below this answer is varied, but there is also an answer given by a simple sum-difference product formula.

How to find the indefinite integral of 1/(sinx+cosx)?

Then if you can't solve this problem because you are not familiar with the differential product formula, you can click I don't know. Because you really won't at this time. Strange things happened when you pointed out that I didn't know. AI will tell you not to worry about the answer. Why don't you write the following question first, classmate:

A Simple Problem of Applying Sum-Difference-Product Formula

Then at this time, you will know that you need to master the sum-difference product formula before you can continue to fight monsters and upgrade. In this way, the four basic formulas of sum, difference and product are in your pocket, and you can apply them when you are skilled. Of course, there is a knowledge point at the end of the first question, which is the basic integral formula. If you are not skilled, ZNX will also have corresponding training.

(B) greatly enhance the computing power of complex problems.

So young man, you have mastered the integral method in the form of 1/(sinx cosx). Let's try the following questions:

This problem only increases the amount of calculation and slightly adds some clever methods to solve it.

This question is just a routine practice, just an extension and simplification, and the answer process is as follows. It can be seen that the calculation amount of this problem is significantly increased, which is also very useful for improving the calculation ability. Also, the newly added knowledge points are the ideas of adding 0, adding 1 and subtracting 1, which you must master when solving problems.

But I believe that most students are just beginning to limit, so let's take a look at this limit problem with a lot of calculation:

Taylor expansion is a general solution to this kind of problem, so the precision of expansion and the calculation of variables are the key points of this problem. I wonder if most of the students who have just started reviewing at this stage can write this question correctly. (The result is -8/3)

Then let's look at a double integral problem similar to the number three of the 23 postgraduate entrance examination:

To tell the truth, many questions have the style of real questions.

Add the absolute value to the same integrand function, and distinguish the symbols in the absolute value by region. I believe that most people in the examination room should have worked out this problem for quite a long time, and I worked it out fairly quickly, because this kind of problem has been trained very skillfully in ZNX. However, there are 880 questions of this type. Lin li's 880 is definitely the most suitable exercise set for the real style. It is still very rewarding to do this.

Climb high, don't forget the way you came.

I think learning is to constantly test one's own level and discover one's own weaknesses in order to improve.

In the process of using Zhihu, AI will recommend you to brush the workbook of the corresponding chapter for testing after you have written a chapter on Zhihu.

In addition, mastering weak knowledge points is also a powerful function when you know how to brush the questions.

AI trains your ability by pushing you questions. When you can't write the topic pushed for you, AI will count the topic into your data, and then examine you in the form of split knowledge points until you master it.

Finally, AI will repeatedly check all the topics you wrote through a comprehensive test to achieve the purpose of reviewing the old and learning new things.

In short, it is through such training that I have full confidence in the postgraduate mathematics exam before I go to the examination room.

Of course, my World War II math score is also ideal, with a conservative score of 120- 130.

After seeing the test paper, I felt like hitting it off. There are even similar questions about knowing how to do it. See the following answers for details:

Did you really hit the target for this year's math postgraduate entrance examination?

Finally, I hope that the subject will get out of the haze as soon as possible. I also hope that more students who lost in World War I will learn from their mistakes, think less and do more, and believe that tomorrow will be better!
