First, choose your own postgraduate entrance examination and continue your study career.

1, I was born in 1996. I studied in a logistics 985 (Laoshan Campus) in Qingdao, and the direction of marine technology hydroacoustics 14. My life in the first two years of college is still calm, and my grades are above average in this major, but there is still a certain distance from my exam-free grades. In the next semester of junior year, when cherry blossoms are in full bloom on campus, the choice of life path after college is straight in front of us.

In fact, choosing graduate school is almost a default thing in my heart, and I never thought about going to work after graduation. On the one hand, it is because the inner maturity is too slow, and the inner positioning is still students and children at home. If I want to be an independent adult in society, my psychological preparation and action preparation are far from enough. On the other hand, it is my yearning for scientific research. After studying college courses, I deeply realized my shallowness. I think I need a postgraduate stage to improve my professional quality and ability to study and research, and also give myself more possibilities in the future.

2. Take the Institute of Acoustics of South China University of Technology as the direction of your efforts.

Choosing the Institute of Acoustics is almost my default. Why? Because I think it is the best place for my major, I must try my best to go to the best place. I heard of South China University of Technology when I was a child. Later, I learned that South China University of Technology is the highest hall of scientific research in China, and my heart is full of yearning. In the field of acoustics in China, there are mainly the following units to recruit graduate students. In the initial selection stage, I also checked the relevant information and consulted teachers and seniors. The system of South China University of Technology is the Institute of Acoustics, the authoritative unit of acoustics in China, and its strength in underwater sound, audio, ultrasound and pronunciation direction is also the top level in China. Every year, a large number of students in my major go to the Institute of Acoustics, no matter whether they are exempted from exams or unified exams. Therefore, conformity is also a reason for choosing the Institute of Acoustics as the direction of efforts.

In colleges and universities, the Department of Acoustics of Nanjing University is also the top level in China, but its research direction is biased towards electroacoustic. My college classmates and seniors have gone to Nantah for graduate studies, but the number is very small; Harbin Engineering University Underwater Acoustic College, Harbin Engineering University is a strong military school with strong underwater acoustic strength, but it doesn't like the northeast climate, so it passes the customs; ; Northwestern Polytechnical University also has a place in the field of underwater acoustics, but I don't know much about this school. Before, my seniors and sisters in the same major didn't go there for further study, so they also died. Institute of acoustics, tongji university. Every year, 5+ students in my major choose there, but Tongji doesn't have the underwater sound direction I want to go to, so I just passed. Then there is my alma mater, but I think I stayed in Qingdao for four years and wanted to change the environment, mentality and rhythm, so I fixed all my memories of my alma mater in the four years of college. In addition, Shaanxi Normal University and South China University of Technology also have teachers who do acoustics, but they don't know much about it. In addition to the systems and universities of South China University of Technology, CSIC's 7 15 (Hangzhou Institute of Applied Acoustics) and Dalian's 760 also recruit graduate students majoring in underwater acoustics, but little is known about them. In fact, I didn't do too much entanglement in the choice of the direction of postgraduate entrance examination. Most students in the same direction choose to go to the Institute of Acoustics. Students in the same direction choose to take the postgraduate entrance examination in four parts, one is our school, the other is Tongji University, the other is the Institute of Acoustics, and the other is Donghai Station of Acoustics (Shanghai Donghai Station is self-enrolled). Fortunately, through hard work, the vast majority of students who took the postgraduate entrance examination have landed.

There is another episode. Every July, during the summer vacation after junior year, the Institute of Acoustics organizes summer camp activities, which is undoubtedly an excellent way to understand the Institute of Acoustics. I also signed up at that time and got the qualification to enter the camp. The Institute of Acoustics has kindly reimbursed the travelling expenses and arranged accommodation and meals during the summer camp. During the summer camp, the institute not only visited various laboratories, but also arranged lectures for various laboratories. The teachers are patient and explain the situation of each laboratory in detail, so that everyone can know what to do when choosing a laboratory and their future direction. On the night of entering the camp, the lectures were arranged by brothers and sisters in various laboratories, which was more grounded and could help us solve the specific doubts at that time. There are several brothers and sisters who came from the same major in my university. It is very kind to meet them. Through them, I also learned more about their study and life in the Institute of Acoustics. At that time, I envied them, envied the good study and living environment provided by the Institute of Acoustics, envied their positive and enterprising mental state of studying hard on a higher platform, which strengthened my determination to come to the Institute of Acoustics, and hoped that I could grow up to be as excellent as them in the future.

Second, about the topic selection.

1, mathematical method

The reason why I didn't choose Math One is because the review area of Math One is relatively wide, and I can't finish it in 60 or 70 days, so I chose the method of mathematical physics. Many people may think that mathematical methods are more disgusting than mathematics, but this is only the appearance. There are only five big questions in mathematical methods every year, and each question has about 30 points. The first two questions are basically the original questions of previous years, so these 60 points can be a shoo-in! The next step is the deformation of the real question in front, which is not too difficult. The five questions are: 1. Singularity and residue, 2. Laurent expansion, 3. Fourier transform, 4. Solving wave equation by separating variables. Solving some partial differential equations with cylindrical function and spherical function.

The most difficult thing is the fourth item. The most difficult thing is that you are absolutely disgusting in the process of reviewing the fifth item. But if you choose this course to review, please don't panic, because I didn't finish reviewing the fifth question last year, so I only wrote a general solution formula after handing out the paper. The initial test is over and the results are just qualified. To be sure, you can safely get 60 points for the first two questions. As long as the last three questions are not well played, it is no problem to get the basic retest line of 30 points and 90 points. In particular, you should try to find partial differential equations by Fourier transform and separating variables. If you can get 40~50 points on these two questions, you must have crossed the line.

2. Acoustics Foundation

Because my major is acoustics, this specialized course is not very difficult for me. The test paper is also 30 points for each of the five major questions. The first two or three questions each year are also the original questions before. At least you don't have to worry about the first 60 points. The third to fourth questions will be a little difficult, but not very big. The radiation and acoustic simulation circuit diagram of pulsating ball source is tested. The last question is a bit difficult. The exam is about radiation impedance. The review of acoustics lies in the basic concepts, and the following chapters can only be reviewed if they are clear. Attention should be paid to: standing wave field, acoustic simulation circuit diagram, vibration principle of Helmholtz buzzer, radiation of pulsating ball source, radiation characteristics of circular piston on infinite partition, concepts of free sound field and reverberation sound field, room constant and reverberation time, transmission and emission coefficient of sound pressure, etc.

Third, English and politics.

1, English:

Freshman has been going downhill since he finished Band 4. At that time, English learning was a process of practice and there was no need to buy any reference books. At that time, I borrowed a book from the library to read and understand the real questions of the postgraduate entrance examination, and I turned to any page, but I used the stopwatch on my mobile phone to do the questions in time, and the reading comprehension of each article was controlled at 12~ 15 minutes. Sometimes all right, sometimes half wrong, and occasionally all wrong. It doesn't matter. I will look up all the new words and save them in my mobile phone dictionary. I take them out for a few minutes every day when I go to the bathroom.

From the beginning of reviewing English to the end of the postgraduate entrance examination, I have done no more than 20 reading comprehension articles, but I have read every reading comprehension article at least ten times. If you happen to turn to an English material in the library and draw a sketch on it, it is basically a good thing I have done (don't cherish books, books are for learning, not for collection). In fact, my method is simple and rude. To sum up, practice makes perfect, and your essence is not much more expensive.

2. Politics:

You can buy a review outline, and it is enough to buy Xiao Xiurong before the exam. Personally, I think I can bring it occasionally in September to lengthen the memory line and leave enough buffer time for practice to make perfect. At that time, I hated Marxism very much. I insisted on dividing philosophy into idealism and materialism, and I always labeled other schools as "XX philosophy", as if his philosophy was the most scientific. But I stubbornly study for the postgraduate entrance examination, but every time I see a conclusion that is inconsistent with my philosophical point of view, I feel unbearable.

Later, when I dragged on for thirty or forty days before the exam, I began to put down my doubts and began to review. I'm too lazy to make a big problem. Three days before the exam, I began to study the answer methods of big questions, and found that the answer methods of most philosophical questions are: world outlook+methodology+combined materials. Economics or current politics are: theoretical viewpoints+materials, which are interspersed in the answers and complement each other. It's best to answer the question in points and estimate the score according to the score. Don't learn from me in the way of reviewing. I was lucky to get 64 points in the exam.

Fourth, the review of specialized courses.

In fact, most of them can be handled by themselves. Copy some real questions, start with real questions and solve them. Don't skip from the first question of the real question every year. You won't go back and do it after reading the corresponding chapter in the bibliography. Not yet. Well, it's urgent. Go back and see! Generally speaking, it is no problem to read a chapter three times. If it still doesn't work, then search online in another way. Sometimes professional things will appear tall in books, as difficult to understand as your goddess. Never mind, this is usually put by scholars who write books or can only be absorbed if you have a higher level of knowledge system.

The advantage of the Internet is that you can understand the origin and development of a tall knowledge point and the problems it needs to solve. This is a good way to understand a knowledge system in a popular way. For example, we often use Fourier transform in science. When we were freshmen and sophomores, many students only knew his mathematical expression, and few people could understand its meaning. There may not be many subtle explanations in the book. At this time, the popular explanation brought by the network is very important. By the way, Fourier transform generally transforms time domain signals into frequency domain for analysis, because many time domain signals are chaotic and untraceable, but transforming them into frequency domain may be a simple narrow-band signal. This brings great convenience to the solution of the problem! According to different transform factors, Fourier transform can be extended to Laplace transform and Z transform. If you have access to the book Methods of Mathematical Physics, you will also know that there is a generalized Fourier transform. )

Say so much nonsense, just want you to understand that the network can be very academic and useful besides playing games and watching TV dramas. Of course, there is no priority in learning, and all who can learn are teachers. Asking people in real life, whether they are schoolmates, seniors or teachers, is often an excellent way. Always ask questions without shame. Here, seniors and sisters are often very important resources! In particular, your school is the same as your major, and you have already taken the postgraduate entrance examination and been admitted. You can pay attention to get first-hand information from them, and don't wait until the seniors and sisters have left school to ask for contact. This resource can be used at the end of your second interview. If you have a good relationship, you can get the internal information of the previous session through them. It depends on whether you are diligent or not. Always remember to be modest and polite.

Verb (abbreviation for verb) Review the examination mentality.

Postgraduate entrance examination is a long-distance race, which tests patience and perseverance. There are not a few people who quit halfway. If you decide to take the postgraduate entrance examination, you should focus on this. Here also involves a most basic question: what are the requirements for postgraduate entrance examination? Mainly for academics? Mainly for better job opportunities? Don't you know?

If it is for academic purposes, please pay 90% attention to the previous review, 10% to find a job. At this age, people should do something. Leave yourself a way out. I didn't get into school, but I still have a job. If you are admitted to graduate school, the national policy stipulates that this is not a breach of contract.

If it is for work, review carefully before finding a satisfactory job. If you find it, go to work and learn more.

If you don't know why you took the postgraduate entrance examination, then you should follow your feelings.

There is a saying that "there is another village." In fact, the mentality of the postgraduate entrance examination should be unintentional, and it is right to work if you fail to pass the exam. There is more than one road in the future, and where to go is not to make a living. There are many people who are frustrated in the examination room in top student on weekdays. Many reasons are not IQ problems but mentality problems. Paying too much attention to the results will often make you fail to play to your due level. I tell myself every day that I can't get into the exam anyway, but I cheat myself to learn more knowledge in the name of postgraduate entrance examination. As a result, before the exam, I will be the same as usual in the college exam. There is also a relatively cheap way, that is, to observe those candidates who are still reading materials before the exam with a leisurely attitude, and to meditate in their hearts with a leisurely attitude: you are all DS, and you are doomed to fail the exam.

6. What should I do if I encounter many problems that I can't?

As I said before, I still didn't finish reading the professional courses before the exam. As a result, when I handed out the test paper, there were really things I didn't like. Two of the five big questions failed, with 30 points for each question, which means I can get 90 points at most. Pause, look around and say to yourself, "There must be a lot you idiots can't do." While maintaining my psychological advantage, I will seriously finish all three questions I can do.

Liberal arts is better. You can make up a lot of content by imagination. For science, some formulas can be derived. Don't just sit there and look like a bookworm without the spirit of exploration. I was more relaxed when I took the second professional class in the afternoon, because I knew that I would spend money to experience the postgraduate entrance examination if I didn't do well in the morning. Facts have proved that children with a good attitude will not be bad luck. After the initial test, I really got 90 points in the first professional course.
