I am a candidate of 202 1 World War I, and now I have landed a master's degree in electrical engineering at Beihang University. Undergraduate students majored in electrical engineering and automation in a non-university in Beijing. Last winter vacation, I decided to take the postgraduate entrance examination, but due to the epidemic situation, reviewing at home was inefficient, with an average study time of less than two hours a day from February to June. After communicating with my classmates in the summer vacation, I found that I was much behind schedule, so I uninstalled all the entertainment software and devoted myself to preparing for the exam. The average effective study time in July-1February can reach 8-9 hours. In the end, I tried to wipe the line for the first time and entered the second interview. With my mastery of professional knowledge and scientific research experience during my undergraduate period, I finally succeeded in the second interview and was successfully admitted to the target institution. The experience of postgraduate entrance examination and the basic situation of postgraduate entrance examination institutions are introduced as follows, focusing on the contents and key points of the initial professional courses and the adjustment of the retest process, hoping to help candidates who intend to choose the electrical engineering major of Beihang University in the future.
First, Beihang postgraduate entrance examination three general situation
The third department of Beihang University is the School of Automation Science and Electrical Engineering. The college has three majors: automation, electrical engineering and machinery. Among them, there are many research directions under automation major, and the number of students enrolled each year is large. However, due to its strong strength, there are many applicants every year and the competition is fierce. There is a mechatronics direction under the mechanical specialty. In previous years, they were all transferred from the hospital, and there were many places to transfer. For a volunteer candidate, the second interview will not be brushed off. Electrical specialty is composed of power electronic transmission, motor and electric appliance, electromagnetic field and other directions, all of which are weak current directions. The retest line of master of electrical engineering is low, but the retest will be brushed; The retest line of electrical specialty is high, but it will not be brushed in previous years, and it will be adjusted in the hospital, with a large number of places. However, in 20021due to the sudden change of re-examination policy, automation, electrical and mechanical majors no longer re-examine separately, but re-examine together. After comprehensive ranking, local admission, and then according to everyone's choice of tutor, finally determine the direction of graduate students. This greatly improves the difficulty of the re-examination of electromechanical students, which means competing with automation students on the same stage, so we can't take it lightly when preparing for the re-examination, thinking that we will be fine after the initial re-examination. Starting from 20021,the real questions are no longer published in the early stage of Beihang University's professional courses, and the difficulty and focus of the professional courses in 20021are much higher than those published in previous years. However, the scores of specialized courses will be looser and the processes will be more distributed. The students who took the exam together, including me, will get higher final scores than they estimated. The re-examination ratio of the third department of Beihang University fluctuated at 1: 1.2, and this year it was 1: 1.3. In the past two years, the number of students enrolled will increase. Beihang University's re-examination is fair and will not discriminate against undergraduates, but it will pay more attention to the investigation of professional basic knowledge, and the re-examination results will not fail.
Professional introduction:
Automation-undergraduate course
Automation major is the key major of the commission of science, technology and industry for national defense. This major adapts to the development trend of digitalization, integration and intelligence, focusing on electricity, combining mechatronics, and developing characteristic professional education based on automatic control and computer information processing.
Electrical Engineering and Automation-Undergraduate Course
According to the development of electric energy transmission, transformation, detection and control technology, based on electronic technology, information technology and computer control technology, and according to the principle of paying equal attention to strong electricity and weak electricity, components and systems, the specialty education with characteristics is carried out.
Second, review experience for the first time.
(1) Specialized courses: The code for taking the elective specialized courses of Beihang University Electrical Engineering is 933 or 935 (the master and master are exactly the same in the unified examination subjects). 933 is automatic control principle (90 points) and digital electronics foundation (60 points), and 935 is circuit (90 points) and digital electronics foundation (60 points). Most electrical candidates choose 935, and a few choose 933, and the difficulty between them is not much different. It is not allowed to bring a calculator in the initial test of Beihang University, so the calculation of specialized courses is very small, which means that the number of questions is large and difficult. Circuits, automatic control principles and digital electronic technology can be used in undergraduate textbooks.
In the basic stage, it is suggested that according to last year's examination syllabus, we should study hard chapter by chapter, read the teaching materials and complete the after-class examples. After-class exercises of the circuit can be completed selectively. For topics with a large amount of calculation, it is recommended to write only the process and not use a calculator to calculate the results. It is recommended to do all the exercises after class. The questions can be browsed and summarized, or they can be completed according to the key points outlined by the seniors. The electricity counting problem is not to brush a lot of questions, but to summarize the questions. Generally, the problem of calculating electricity is to understand the solution of a kind of problem, so when you encounter this kind of problem, it will be solved. And the original title in this year's textbook appeared in the initial test of Digital Electricity, and there will be original title adaptations in previous years, so it is extremely important to understand the original title in the textbook. Pay attention to be comprehensive in the learning process, don't limit yourself to the key content, as long as it is within the scope of the outline, you must finish all the studies, and don't take any chances. It is enough to read textbooks and do problems in the basic stage. If you want to listen to online classes, it is not recommended to take up too much time. You can selectively look at difficult knowledge points. In the intensive stage, it is recommended to do the real questions in previous years first. Because the real questions in previous years were relatively simple, they were all brushed up soon. At this time, it is recommended to find some real questions for the circuit postgraduate entrance examination of famous electrical schools, and only write the process with a large amount of calculation. This part of the circuit must do more problems and master the basic knowledge and problem-solving methods skillfully. Because there are fewer schools in the electrical specialty that take the electricity meter test, the electricity meter part can refer to the real questions of Harbin Institute of Technology. The last question in the electricity counting part is often comprehensive and difficult. It is not recommended to take up too much thinking time during the exam. Just grasp some key points and try to get the process points. This year, the investigation form of professional courses is five three-point multiple-choice questions+nine fifteen-point big questions. The investigation form of specialized courses may change every year. If you have difficulties in specialized courses, you might as well sign up for a specialized course, such as one-on-one tutoring course for xxx graduate students, which is highly targeted, flexible in class time and free to answer questions after class, which is very helpful for preparing for specialized courses.

(2) English 1: Good English foundation and good sense of language. I passed CET-4 and CET-6 at one time, and got 550+, so I didn't work hard for the postgraduate entrance examination. I think the most important thing for English postgraduate entrance examination is to master skills+enough words+memorized composition templates. English one has a strong reading ability. When I first started doing it myself, an article often made three or four mistakes. Later, I read some explanations of reading skills, and even if there are not many words in each article, I can't make more than two mistakes. There are many famous English teachers, and each teacher has his own characteristics. I suggest you spend a day seeing more teachers and choosing the one that suits you. I follow Chen Jianing in reading and Wang Jiangtao in writing.
Word accumulation is one thing that runs through the postgraduate entrance examination. At that time, I recited the little red book with a booklet, memorized the words, and summarized the words I was really reading. It's rare to recite words for an hour or two or watch a word class honestly. It was okay in the early stage, but it was a waste of time in the later stage. English composition routines are also very deep, so I must practice more on the basis of memorizing templates. This is what I suffered. At that time, I memorized a few templates but didn't use them much, so I learned them mechanically during the exam, which led to a long time in writing.
(3) Mathematics 1: Mathematics is a very important subject and an important means to widen the gap with others. In the early and middle stages of postgraduate entrance examination, mathematics must be regarded as the top priority of review. There are also many famous teachers in mathematics. We shouldn't just follow whoever listens well, but spend a few days listening to each teacher's course and finally choose the teacher that suits us best. I followed Mr. Fang Hao throughout the math process. Because I have a good foundation in mathematics, I got 90+ in the undergraduate course and I am interested, so I spend more than half of my time studying mathematics every day in the early and middle stages. If you don't have a partner who is particularly good at math, you can choose to buy and join the math question and answer group, which will answer questions and solve problems in time. Mathematics is as important as English. Many students around me can't do the real question before 1999, but this year's exam showed a very similar question to the real question before 1999. Therefore, the real problems of mathematics should be done repeatedly, summarized and analyzed.
(4) Ideological and political theory: The political review plan is as follows:
I began to review politics in September. At first, I spent an hour watching Xu Tao's videos every day. Because watching video is too inefficient, I gave up after watching it for more than ten days.
From September 9th to the end of June 10, I spent more than two hours every day watching intensive lectures and training with 1000 questions. Now it seems that it is not cost-effective to spend more than two hours watching intensive lectures and training, mainly because the books are too thick to remember at all and the time is a little longer.
The book Strong Grass in the Wind was published in June 5438+10. This book can be said to be a condensed version of "fine and concise", which refines important knowledge points and is worth buying. In the later period, you don't have to bring "Fine Talk and Refinement" every day, just read "Strong Grass in the Wind".
165438+1In mid-October, small 8 began to come out. At this time, the prediction papers of various famous teachers were published accordingly. It is suggested that after finishing small 8's multiple-choice questions, you can buy some papers from other famous teachers for multiple-choice questions. I have time to do short answers, but I don't have time to read them. You probably know the process of answering questions.
Xiao Si came out in June+early February of 65438. What you have to do is to brush the wrong multiple-choice questions after Xiao Si, and recite Xiao Si briefly every day in a planned way.
Personal advice:
If you have time, you can watch Xu Tao's video, and the praise is quite high. Of course, it depends on personal needs; In addition, in the pre-review of political suggestions, first do 1000 questions, some political questions are more conventional (the kind that normal people can choose right), and then take out the wrong questions of 1000 questions in the intensive reading class to strengthen memory, suggesting that the pre-political time should not be too long; Before 1 1, it can be said that you only need to focus on the multiple-choice question of 1000 and do it two or three times.

Third, the second interview preparation experience
The second interview time of Beihang University is relatively early, but for the students who rank lower, we must pay attention to the adjustment information when the adjustment system is open. The second interview is divided into written test and interview, and the interview is divided into English interview, professional interview and comprehensive interview. 202 1 in 2020 is an online re-examination and there is no written examination, so the atmosphere of the re-examination is relatively relaxed as a whole. The master's re-examination is conducted by a professional teacher, who needs to fully understand the professional knowledge of electrical specialty. Before the re-examination, you should contact your previous seniors and sisters to understand the questions that teachers often ask in the re-examination, and grasp the key areas to prepare some answers in advance. If you are asked questions that you can't answer, don't just say no, but try to analyze or talk about some basic knowledge. Master's re-examination is a mixture of three majors and divided into more than a dozen groups for re-examination. There may not be any electrical teachers in your group, so you should also review your professional knowledge of automation when preparing for the second interview. In addition, this year's second interview will ask conceptual questions of mathematics, such as explaining independent and related concepts. Therefore, we must also make targeted preparations. The comprehensive interview is mainly to know whether there is competition experience or scientific research experience in the undergraduate stage. If there is, it is very extra points. If not, don't be nervous. You can talk about your comprehensive courses.
Fourth, it is recommended to encourage.
If you really can't remember or understand any subject, brush it in the most stupid way. The two most important points throughout the postgraduate entrance examination are to practice the words well and not to stagger them. It is not that the writing of art is at least square. Then, you need to take a three-hour mock exam before the exam, simulating which one you do first and then which one you do for three hours. Don't go to the examination room, knowing that you won't have time to write. All subjects will do what they can first, and then go back and struggle for the first time. No, let's talk first.
Personally, the most important thing is mentality. No matter how difficult it is to study in the future (especially when studying alone in World War II is not as lonely as in school), even if you have the idea of quitting, please adjust it within one day to keep your idea of never giving up when taking the postgraduate entrance examination. Never give up halfway. At least 100 W people give up halfway every year, and I'm sure you will be admitted to the postgraduate entrance examination day. Finally, health. It takes more than ten hours to sit for the postgraduate entrance examination every day, so it is easy to get sick. It is recommended to go out to exercise two or three times a week, eat reasonably and stay healthy so as to review better. As long as you firmly believe that you can pass the exam and stick to the end, then you won't be bad.
