Successful experience of postgraduate entrance examination in materials and Chemical Engineering (metal) of Beijing University of Aeronautics and Astronautics in 2023

I am 2021 He took the postgraduate entrance examination and landed at Beijing University of Aeronautics and Astronautics, majoring in materials and chemical engineering （ Metal direction ）, Bachelor degree in material forming and control engineering, Northeastern University . I started from 2020 year 2 At the end of this month, I began to prepare for the postgraduate entrance examination , Keep on until the end of the first test , On the whole, I was quite satisfied . Now I will share with you my experience in preparing for the postgraduate entrance examination and some of my experience in preparing for the postgraduate entrance examination , Share the general situation of Beihang University for the postgraduate entrance examination of materials major and the test preparation experience of English one , I hope it can be helpful to the students who have worked hard to prepare for the war .

One 、 Overview of the postgraduate entrance examination of the school of materials, Beijing University of Aeronautics and Astronautics

（1） Preparing for the exam is challenging . As a of Beijing 985 Universities and Colleges , without doubt , Beihang has higher requirements for postgraduate entrance examination as a whole , At the same time, the material specialty of Beihang was rated as A+（ A total of three institutions have been rated as A+）, This makes it more difficult to successfully prepare for the Beihang materials major . I personally think , The most troublesome thing for candidates majoring in Beihang materials is the professional course , The professional courses of Beihang materials are divided into three directions ： Metal direction 、 Inorganic nonmetallic direction and polymer direction , I chose the metal direction , Therefore, the following is mainly about the metal direction to share .① There are many specialized courses . The major courses of Beihang materials include physical chemistry 50%、 Modern research and analysis methods of materials 30% Materials science and foundation in the direction of metal 20%, The content of the three specialized courses is huge . Maybe the new students do not have this concept , Let's compare . I learned that the chemistry major of Beijing University of chemical technology has only one specialized course ： Physical chemistry ; Xi'an Jiaotong University's major courses in materials science are the foundation of materials science . It is worth mentioning that , Although the score of material science and foundation is only 30 branch , But it includes a Book , This is enough to see the contents of professional courses .② It is difficult to calculate . It is not allowed to bring a calculator during the written examination of Beihang materials specialty , Just to emphasize , Calculators are not allowed ！ In the part of Physical Chemistry , There are many decimal multiplication and division operations , The data is completely irregular , One of the most common thermodynamic formulas ：pV=nRT, Where the pressure p Usually atmospheric pressure 101.25kp, constant R=8.314, Thermodynamic temperature T, Unit is K, It's usually 298.15, Generally, three significant digits shall be reserved for operation , Without the aid of a calculator , The amount of calculation is conceivable .③ A long time span . Because the specialized courses involve a lot of contents , Generally, professional courses need to be prepared in May and June , And then until the end of the first test , The time span is very long . Due to the large number of examination questions , The calculation is demanding , If you want to go to a higher professional course score , In the later stage of the postgraduate entrance examination, it must take a lot of time to calculate the real problems by hand and recite them .④ Hypertopic is very common .

According to the above , The average score of professional courses of Beihang is low , Only 100 about , However, Beihang Xueshuo academy generally needs 360 branch , Even if you are a master, you should 335 branch . Therefore, the requirements of Beihang for the other three branches are also very high . Plus regional factors , Politics and English in Beijing have a negative effect , So if you want to get a good total score, you must be careful in every course , Give plenty of time . To sum up, the preparation of Beihang materials major must be done as soon as possible .

（2） There are certain skills in preparing for the exam . Test preparation skills are still concentrated on professional courses . Although there are many contents in the professional course exam , But the routine and emphasis are very prominent , And there must be true questions in the exam , Its proportion is relatively considerable , In particular, the focus of modern research and analysis methods of materials is only the first three chapters . In addition, there are obvious rules and emphases in the answers and short answers of physical chemistry and material science , The examinee plans the key points for the professional courses through the seniors and sisters , You can do more with less .

Two 、 Review experience in the preliminary exam

I will share with you my initial test experience in chronological order .

2 End of month —5 Only English and mathematics were conducted in January

English ： With the help of scallop words APP I recited all the vocabulary for the postgraduate entrance examination , And reviewed both sides . mathematics ： Watch the video of Zhang Yu's improvement class , do 《 Basics 30 speak 》（ The line division section ）, Take notes of basic knowledge and mathematics .

Specialized courses are textbooks + The true theme of the past years , Read the textbook again and again , Do the real question over and over again .

3、 ... and 、 Re examination preparation experience 　

2021 The re examination of Beihang materials in was conducted online . Beihang is a slow bird , Generally, the second round exam will be held at the end of March , At the back of all colleges . Full marks in the second round exam 220 branch , In the form of interview , The interview time shall not be less than 20 minute . Affected by the epidemic ,2020 Year and 2021 The second round of the year was conducted online , Full marks in the second round exam 220 branch , In the form of interview , The interview time shall not be less than 20 minute . The interview mainly assesses the following aspects ：

During the actual reexamination , The second round is generally divided into three parts ： Questions about political issues , Questions about professional English level and professional courses . I remember the process of my second interview was ：（1） Translate paragraphs , The material is brittle at low temperature , Plastic at high temperature . I didn't understand , The answer was sparse .（2） What impressed me most about chang'e-5 （ I want to ask about politics ）, I also asked about the application of Beihang materials in the above , This is my strong point , The answer was steady .（3） The professional course first asks about the structural changes of high carbon steel during quenching ; Then there is how to distinguish supercooled austenite ; I mentioned observing the appearance , The teacher then asked how , I said, SEM、TEM; ask again SEM The details of , I can't answer ; The last question is EBSD Do you know? … I said I only knew the name .

Actually, take a break after the first test , You should start preparing for the second interview . First, choose the direction you are interested in and the teacher you like , Email them , Make a good impression . Then according to the experience of previous years , Review the written content of the second round exam （2020 And 2021 Only interview is available for online reexamination ）, Then review the textbooks of key subjects in the undergraduate course , In this way, the key links of written examination and interview can be stable . Then prepare your own Chinese and English self introduction in the review process , Recite professional vocabulary , Prepare simulated English Q & A , Do not let English score in the second test .

There is a characteristic in the second round examination of Beihang materials specialty ： The second round examination sequence is directly linked to the initial examination results , The higher the initial test scores, the higher the candidates , The interview sequence is more backward . Due to the heavy workload of the teacher during the interview , It usually takes one day to complete the interview , So in the evening , The teacher lacks energy , It is customary to ask simple questions when asking questions , And the interview time is not long . thus , Candidates with high scores in the preliminary examination have great advantages in the interview . So , It's safe to try again , The first exam must be as high as possible .

Four 、 At the end

I have two paragraphs to share with you .

（1）“ Process is more important than result ”, Only those with good results are qualified to say , Don't comfort yourself .

（2） Many people say that taking the postgraduate entrance examination is like washing clothes in a dark room , You don't know if it's clean , Can only be washed over and over again . Wait until the moment you go to the examination room , The lights are on . Have you found , Some people forget to add washing powder , Some people use washing machines . But as long as you wash it carefully , Your dress must be as bright as new . And you will , Every time I wear this dress, I will think of those years .
