Preliminary experiment
I always take four courses: Math 1, English 1, Politics and 837 Physical Chemistry. Distribution of Time and Energy In the process of preparing for the exam, subjects with a full score of 150 spend at least 0.5 times as much energy as subjects with a full score of 100. There is no need to review in the early stage of politics, and it is not too late to start in September. You can spend your time mainly on math and professional courses. If you have a good English foundation and have passed the TOEFL IELTS test, you can also allocate less time.
In addition to the three subjects of the unified examination outside the professional courses, there are many other people's experience posts. Specific methods and steps can be searched by yourself, such as the answers to such questions as "How to take the entrance examination for mathematics 140" and "How to take the entrance examination for English 80". It should be noted that the postgraduate entrance examination for chemical engineering majors in Tsinghua is Math I, while the postgraduate entrance examination for chemical engineering majors in other schools is generally Math II. Here, I also briefly talk about my experience in preparing for various subjects, focusing on the experience of specialized courses.
mathematics
Because it is mathematics one, it has more contents than mathematics two, and there are many higher triple integrals, lines and areas, vector spaces generated by lines and a probability theory. It is recommended to review as soon as possible, starting at the latest in summer vacation.
The review period is divided into three periods: the basic strengthening period and the sprint period. July to September is the period of foundation consolidation, during which you can spend more time on mathematics. Reviewing mathematics is mainly about reading books and watching videos to do problems. Time and energy are allocated according to (watching videos+watching teaching AIDS)/doing exercises = 1. Here, high numbers and high lines are good substitutes for mainstream materials. In probability theory, I personally recommend Zhang Wei's intensive class video and Zhang's "Methods and Skills of Solving Problems in Probability Theory and Mathematical Statistics". Zhang Wei's video class is easy to understand, and some problems in Zhang Lizhuo's book are beyond the scope of postgraduate entrance examination.
Whether watching videos, reading books or doing problems, we should pay attention to the use of time and quality. You can stop and think about examples when watching videos, and you can't copy them all without thinking; When reading teaching AIDS, you can establish your own knowledge system after reading each chapter, and you should use a pen to do examples. Before doing the problem set, you must know something about the knowledge system. When you do it, you should summarize the problem-solving methods, find the weak points and return to the teaching AIDS in time, or do more similar problems to check for leaks.
English
The main thing is to do real questions, and the reading of real questions is the most important. When doing it, it also emphasizes quality and reaches three levels in turn:
Every word in the article can be understood, every sentence in the article can be explained orally without looking up the dictionary, and every option of every question in the article can be understood. For example, you can find the corresponding sentences in the article, and finally understand the questioner's thoughts in combination with the article. In order to achieve the above effect, you can do it several times. Some people think that they will remember the answer to the question once, but in fact, they may still make mistakes if they do it again. This is the third point mentioned above that has not been achieved. If you do it again, you still can't understand many sentences and words, that is, 1 and 2 points are not reached, which shows that the quality of doing it is low. So you can do the real questions several times, not to mention saving them because you think there are fewer questions.
When the composition can be a real composition topic, classify the real composition and collect excellent sentence pattern summary templates. For example, many years' essay topics are about social phenomena. You can sum up what you say at the beginning and at the end, what sentence patterns can be used to express and evaluate the phenomenon, and what classic measures can be taken to improve the phenomenon. Summarize your back, and then practice with practice.
As long as the real questions and new questions in translation are well done, gestalt will follow.
politics
It is not too late to start in September. Turn over the essence in the early stage, talk about refining, and do Xiao 1000. After the knowledge points are summarized or books like "Strong Grass in the Wind" or "Leg Girl" are published, replace the essence with refinement, and then do the Xiao 1000 question. It is also possible to practice multiple-choice questions mainly in the early and middle stages, and then recite the big questions above when Xiao Ba Xiao Si comes out. Ma Yuan's basic philosophical principles are fixed and can be recited in advance. When preparing for the exam, don't feel heavy. It can be used as a temporary relief to review the adjustment and formula of mathematics and professional courses. The above methods are exceptions to the pursuit of high political scores, but the cost performance is not high.
Politics is arranged according to the personal review schedule, but it doesn't need to start too early. The subjects that I spend the least time on are also subjects that I don't need to worry about. It started three or four weeks before the exam. I've only done four and eight. If you can't answer the short answer questions in the examination room, make up with your own content and materials.
physical chemistry
Many people hesitate to apply for the Department of Chemical Engineering in Tsinghua because of the difficulty of its specialized courses, lack of information and ignorance of its style and situation. Here I will introduce its style in detail.
837 physical chemistry is very difficult, and most of the exams on 20 19 are above 80% or even fail, and it is not a technical difficulty, but a conceptual difficulty. It pays attention to the detailed and in-depth real understanding of the conceptual basis of knowledge and its flexible application on this basis, and cannot be vague about any materialized concept. It is not feasible to think that you can do problems as long as you can use formulas, because of its propositional style and by doing real problems in previous years, you will find many objective problems. This year (2020), you will also get 60 points for single choice, 50 points for discussion and proof analysis, and finally 40 points. In previous years, I also filled in the blanks with more than 70 points. Many of these objective questions give general conditions and do not need complicated calculations. They just need to give the results of a conceptual analysis. For example, if the enthalpy change is positive, then you can choose whether the internal energy change is positive or negative. For example, if T is given in symbolic form, I will tell you what kind of system it is, and let you give the expression of enthalpy change and fill in the blanks. This kind of topic asks a lot of questions, and the concept is vague or unclear, so it is difficult to think of it. 20 19 is also dozens of fill-in-the-blank questions and multiple-choice questions. There are conceptual short answers to the big questions, such as how to understand the adiabatic process, give a scientist's operation steps and ask you if it is reasonable or not. After answering a huge objective question with a high score, I finally got all the answers, but there were many uncertainties, and I didn't get it right. I can't predict how many points I will get in this exam. Short answer analysis questions are also graded according to the depth of the solution. If you don't have your own mature understanding, you can finish the answer but the score is unknown. Because calculators are not allowed to be used in calculation problems, there are certain skills when ln appears, and it is necessary to substitute it back and forth in the formula on the basis of understanding the concept. Although it is so difficult, the scores of 20 18 and before are still considerable, and there are many 120, because there are many original questions, new questions are not dominant and the difficulty is not great. Since 20 19, there have been more and more new questions. It is said that the proposer has changed, which I have not verified. However, no matter how it changes, the style is the above, focusing on a detailed and in-depth understanding of the conceptual basis of knowledge and flexible application on this basis. So as long as the review is in place, you can still get a relatively considerable score, at least enough to be admitted.
The following are some review suggestions.
Postgraduate entrance examination is also an exam, and the time for review is limited. Reviewing the style of proposition can get twice the result with half the effort. The first is the textbook, two volumes of Basic Physical Chemistry and Physical Chemistry Counseling and Answering, edited by Zhu. The concepts in these three books should be very clear. After all, Tsinghua paid attention to a detailed and in-depth understanding of the conceptual basis of knowledge. This can be done by reading the textbook several times, thinking more when reading, and remembering on the premise of understanding. You can start to sort out the knowledge system of each chapter. The teacher loves to say, closing your eyes is like showing a movie, and the whole materialized knowledge system can emerge in your mind one by one.
And then the real problem. The real questions and textbooks complement each other. When doing real questions, I found that I couldn't go back to the textbook in time and ponder the ideas of the proposer. The real question is also done several times before it can be done thoroughly.
Textbooks, pamphlets and real questions have the highest priority and importance, followed by some tutorial books and problem sets. Here are some books recommended, including Shen's Guide to Physical Chemistry Learning and Postgraduate Entrance Examination, Zhang Desheng's Thinking Questions of Physical Chemistry 1 100 Cases and Lu Deyi's General Outline of Physical Chemistry Postgraduate Entrance Examination. Shen emphasizes method summary and concept discrimination, which is more convenient for early concept understanding and framework establishment, especially for the induction of entropy change and enthalpy change of various thermodynamic systems. Thinking questions 1 100 cases are mainly various thinking questions, which are analyzed in detail. Lv Deyi's book is very old, and there are many early postgraduate entrance examination questions in other schools, so you can choose to do it yourself.
take a reexamination
Because the re-examination and the initial examination each account for 500 points, the re-examination is as important as the initial examination. The second interview consists of 100 written test and 400 interview. The written test only took the principle of chemical engineering, and my review method at that time was mainly Lin Aiguang's basic study guidance and problem solving. This book is accompanied by Tsinghua's postgraduate entrance examination questions and final questions before and after 00 years, so that I can get familiar with the knowledge points of the exam, and then check and fill in the gaps according to Jiang's textbook Principles of Tsinghua Chemical Industry. For example, I didn't learn much about evaporation when I was an undergraduate, but I came across it when I was doing a postgraduate exam a few years ago. Let's take a look at the evaporation part of Tsinghua's textbook to check for leaks and fill gaps.
20 19 tested four big questions, evaporation, fluid, heat transfer (or absorption, I can't remember) and distillation. Among them, evaporation is a large section of seawater evaporation and desalination. Several empty spaces were dug to fill in, and the rest were calculation problems. The big problem of distillation even reached 40 points. Prepare to introduce yourself in Chinese for 5 minutes before the interview and memorize it. Award-winning certificates, papers and anything can be brought, and the interviewer will circulate them. For the reading and translation of English documents, we should at least master basic professional vocabulary, such as rectification English, and some basic vocabulary translation. In the English reading and translation materials of 20 19, the Department of Chemical Engineering of Tsinghua was introduced.
You can talk about graduation project without scientific research experience, and you can talk about scientific research experience with it. Self-introduction can guide you to develop in the direction you are good at. If not, the interviewer may ask professional knowledge questions. There will be an interviewer who will look at the report card, pick out the subjects you failed, ask why you failed, and prepare yourself in advance. Although the direction you filled in on the website when you signed up for the postgraduate entrance examination is not the final direction, the interviewer may ask you why you chose this direction, what is your understanding of this direction, and what is the status quo of cutting-edge technology.
Let's talk about the second interview. This year's re-examination refined the small direction, so the scores vary greatly. As I said before, some people can't get into the second interview at 390, and some people can be admitted at 360. I got a higher score in the second interview. Due to the epidemic situation, the second interview was conducted online. My suggestion is to practice oral English well. Standard English is an advantage. Secondly, you must be familiar with your graduation thesis or graduation design. During the second interview, many questions of the teacher revolved around the graduation thesis. So everyone must be familiar with their graduation thesis. The re-examination questions of Beijing Institute of Technology are relatively basic, and the investigation features are broad and shallow. I think some of them are more open. For example, if I draw a question, then I will talk about my chosen future development prospects.
In the process of preparing for the second interview, you must communicate with your seniors and sisters. There is no exam outline for the second interview, and what to take this year is very variable. Knowing the content of the exam as soon as possible is more conducive to preparing for the exam efficiently. Re-examination content: introduce yourself with ppt, ask and answer questions in English, and set relevant questions.
Finally, I want to give some advice to my brothers and sisters. Postgraduate entrance examination is certainly not an easy task, because if it is easy, everyone can do it, and graduate students will have no gold content, and more and more people will take the postgraduate entrance examination in the future. If you decide to take the postgraduate entrance examination, you should devote yourself wholeheartedly, grasp the main contradiction and learn to refuse. Brother Shi also wants to tell you that the relationship between love and postgraduate entrance examination is that whether you talk about it or not, the biggest influence on you is mood fluctuation, so everyone must pay attention to it and remember that if he misses you, he misses a treasure.
However, we should also remember that postgraduate entrance examination is not a sacred thing, nor is it the only way out. Everyone's mentality must be flat. Finally, I want to send you a word. I saw it the other day and liked it very much. There are some things that God can't do, and that is to protect you! The power went out, the car broke down, and it was late. I missed it. I loved the wrong person. Don't complain. Many things in life will be late, but everything is the best arrangement. Getting is not necessarily a blessing, and losing is not necessarily a curse. Life has its own ferry and its own boat.
Finally, I wish everyone a smooth landing!
1, I will overcome everything with my mind and body. It's okay. We will succeed.
2. Failure doesn't belong to me. I have nothing now. I only have the ability to persevere.
3, arrogance, calm your mood, step by step, no hurry, no slow, like a duck to water, success!
4. I study hard at the cold window and study hard, which is to uphold a belief that I want to take the postgraduate entrance examination. The fate of change. Let's start with review.
5. Learning is a boring mechanical exercise, and cultivating interest is the continuous strength to support your success in postgraduate entrance examination.
6. Nothing is difficult in the world, as long as you are willing to climb. Prepare from basic vocabulary and long sentences to meet the challenge of English for postgraduate entrance examination.
7. Postgraduate entrance examination is not easy, and it is not easy to realize your dreams, but! Doesn't mean impossible. Persistence, patience, hard work, no problem getting into Tsinghua!
8. Without a clear goal, a specific plan and strong execution, you are waiting for failure.
9. Learning is like sailing against the current. If you swim against the current, you will try to support it. Once you relax, you will retreat to Chihiro. This day is a pity, so cherish the second sound.
10, how many beats can life have? When will you fight at this time?
1 1. Why didn't you cherish time at first? It's really too late now. Is it too late to regret? Today, seize today!
12, only dreams, no efforts, no achievements.
13, if you want to get ahead, you must first walk into loneliness.
14. Postgraduate entrance examination is the most direct way for me to prove my value, the shortcut for me to change my present living condition, and the only way for me to truly experience college life.
