About school choice

The 22nd postgraduate entrance examination, majoring in chemical engineering of South University of Technology. I chose South Institute of Technology because I like Nanjing. Southern Institute of Technology is a very famous school in Jiangsu, and its chemical industry and materials rank very high in the country.

Students should pay attention to the 22-year reform of specialized courses. Chemical engineering and material engineering have corresponding inorganic analysis to choose from. Let's share some experiences.

Initial experience

(1) Review suggestions for various subjects

About mathematics:

Let's start with the most important math. For our science and engineering students, it is no exaggeration to say that mathematics is the best in the world, so we must attach importance to mathematics and allocate the most energy and time to mathematics. According to my personal review rhythm, I began to watch the video of Tang Jiafeng's basic course with my girlfriend from the winter vacation, that is, February and March. Here is a little trick to share with you. Never trust your self-discipline at home. If you have a research friend to accompany you, the efficiency will be greatly improved. Of course, it would be better if you are a couple who urge each other to learn.

When I was in the basic class, I didn't start doing exercises at the same time. I just followed the practice in the video class of Teacher Tang's basic course. Here I suggest that you do exercises while watching the class, which can achieve better results. After school, due to the pressure of schoolwork and competition, the review of mathematics is relatively backward, but I try my best to keep in touch with mathematics every day. This is a good habit, I suggest you implement it, because there will be more homework in the third semester. While balancing your homework, you may not have much time to conquer mathematics every day, but you must get in touch with mathematics every day, even if you do a problem. Because I participated in the chemical design competition and successfully entered the national competition, my summer vacation time was basically abandoned, and almost all my time was spent on the competition. Summer vacation is the golden age of brushing questions, which is especially important for mathematics. Try not to go home this summer vacation. It will be a good choice to stay at school to review. After entering September, I am very nervous, because professional review must also be put on the agenda at this time, but the most important thing is not to ignore the review of mathematics. I still have to spend the most time on math. On the basis of brushing questions in summer vacation, I can look at the courses of intensive classes, brush more questions to improve, or start to contact simulation papers. The tasks of June 10 and June 1 1 focus on the real and simulated questions over the years, in which attention should be paid to the real questions, and it is suggested to sort out the wrong questions while doing them. True questions are the best standard to test yourself, and you should understand every question. It is normal to do some forecasting papers in June 5438+February. At this stage, you may spend a lot of time on politics, but I suggest you keep about 2 hours of math study time every day. When the exam is approaching, it is not recommended that you delve into some difficult and strange questions. You can review the wrong questions sorted out before and consolidate them. Judging from the trend in recent years, at present, the requirements for concepts in postgraduate mathematics are getting higher and higher, so everyone must pay attention to concepts in the review process.

About English:

Words are the foundation of everything. I recommend you to recite the word book and APP together. Regarding the real question, I suggest you buy the sword yellow book for the first time, and there will be a detailed analysis over the years.

I suggest you only do reading in the early stage, because I took English II, and the real question starts from 20 10. Read an article every day, don't break it, the important thing is to keep your hand feeling. It is normal to make three or four mistakes at the beginning of reading. Don't lose heart, recognize the wrong reasons of each question. According to my personal experience, 99% of the reasons for doing wrong questions are illiteracy. After finishing the first time, you can brush it for the second time, and you can buy cheap real questions over the years for the second time to avoid the traces of the previous papers from affecting the answers. The difficulty of cloze has decreased in recent years. I advise you not to give up, but there is no need to spend too much time. The point is still to read four articles. Of course, composition is also an important part of English for postgraduate entrance examination. If you have a good English foundation, you can recite the template directly and then supplement the content according to the content of the question. If you have a basic knowledge of English, I suggest you follow some courses and have a clear composition structure. We recommend Pan Yun's nine-square grid method. After you have the structure, you can fill in the blanks. Zhou Sicheng's sentences are very good and can be used for reference.

About politics:

Summer vacation began to prepare, mainly in Ma Yuan. This is the basis of politics. Find out the principle and do it with 1000. Other people like Shi Gang and Mao Zhongte have to be familiar with the price comparison. Politics is mainly a multiple-choice question. After answering the questions, major organizations will come up with many forecasting questions. You can buy one more book, learn from each other and memorize it. In case it doesn't work, the problem can provide us with a lot. Math: Because Math II has a line generation, in fact, the high number part of Math II is deeper than Math I, because Math I still needs to leave scores for mathematical statistics. When you start reviewing in March, you should write down all the definitions and theorems in the book, and don't do after-school problems just because they are simple. Some questions are still a little difficult.

I have been using brother Yu's books. I finished reading lecture 18 in June. At this time, I have to come back and watch lecture 18 again to improve my knowledge framework. By the way, I also need to prepare a notebook to write down good topics and good ideas at any time. Mathematics is made! Math will take a lot of time, but after the exam, you will find it worthwhile. Then there is the topic source 1000. All the above questions are difficult and abusive. The difficulty fluctuates greatly, which is in line with the characteristics of postgraduate entrance examination. At that time, it was also done chapter by chapter, so I didn't finish it in the end, so I could only choose some better topics. And then the real problem.

This must be done well. In the past few years, the real questions were done very quickly, almost less than 1 hour. In the next few years, especially after 10, remember to hold the table and do the questions. You can test your ability and see how many points you can get. If it is not ideal, take notes again, write down the classic questions and do the real questions several times. Later, brother Yu had to write eight sets of papers, which was very difficult, but the method was worth learning. There are also the last four sets of papers, you can add more to yourself as appropriate, but you must be familiar with the real questions!

About specialized courses: this major should take specialized courses to investigate the principle of 828 chemical engineering, and it is suggested to review specialized courses in the summer vacation.

The first round of review begins with books. I think watching video lessons is a waste of time. Therefore, it will be boring to read the books supplemented by reference books directly this time, but we must pay attention to the detailed investigation of chemical engineering principles. Any detail in the book may be tested. On the way through the pages, you can take out your notebook and write down the difficulties and difficulties, which will be of great help in the future. Because I participated in the chemical design competition, I basically didn't have time to take the postgraduate entrance examination during the summer vacation, so I was already very nervous in September. In order to save time, I brush the real questions directly after reading the book. No matter which professional course it is, the real questions are particularly important, and 828 is no exception. I suggest you brush the real questions by module and chapter for the first time. Before you brush the questions, you should sort out the knowledge points in this chapter and consolidate them. After that, you will get twice the result with half the effort. Brush the questions for the second time, just press the set of rolls directly. You don't need a reference book when you brush. Check your true level, brush a few more sets and find the feeling. Of course, if you have enough time, you can brush the titles of some reference books, and even the original titles of other reference books will appear in the real questions.

Re-examination experience

Let's talk about the proportion of the second interview.

Written test 30%, interview 60%, English 10%. Therefore, everyone should pay attention when preparing for the second interview (if you just cross the line, you will have to refuel, and you will see a counterattack in the admission list). Written test 64, interview 92, English 77. The final retest score is 82. 1, and the initial test plus retest is 397.20.

Because the written test is simple, this year's written test topic is the same as the initial test topic. In addition, materialization is something I do once when I review myself. Write formulas when you encounter problems, but don't press the calculator. Pressing the calculator in the examination room is not so slippery, and there is not enough time. However, some people have done the real questions three times and got more than 90 exams, which is worth learning. Materialization is suitable for scoring in a short time. Therefore, it is suggested to try the original work for the first time and re-examine materialization.

Talk about the second interview process.

First of all, people are concentrated on the first floor of a building, and their mobile phones are collected and labeled. The teacher will follow them when they go to the toilet. Interview group teachers only know their interview group by drawing lots a few minutes before the interview. It seems that there are five interview groups, and every time they go to the interview at the same time, the results are similar. The teacher said it was to reduce the differences between groups. For example, you and I are both around 380, and interviews are in progress. Also, the certificate and grade examination certificate you brought here at the Institute of Chemical Technology cannot be brought into the interview group. The teacher is afraid that these will affect his judgment on you, so don't worry about not getting the certificate. Fair!

What questions do you ask me? Remember to smile as soon as you enter, and the teacher will always smile. Confident that there are five teachers, one English teacher (estimated to be a professional teacher), three professional teachers and one teacher who takes notes. Then the teacher asked, are you ready? When you are ready, the English teacher will ask: Here are 1 and 2 questions. What do you choose? I chose 1, and then began the Chinese-English translation of "chemical engineers need to have the characteristics of chemistry, physics, mathematics and materials". The second English-Chinese translation of "I have only heard this book" ... chemical equality ... by chemical engineer "asked the teacher to repeat it three times, and the sentence was too long. If I ask the teacher to repeat it, I will skip it, but I still have to translate something.

Then ask "whatisyour". . . Plan? How to achieve it? "This can be prepared. There are strategies for re-examination, so you have to prepare in advance and be prepared! Next is a professional interview. " There are 1-7 questions, which one do you choose? "Answer" 3 ",the teacher said that many people choose this. The first question is "how to distinguish the first author from the correspondent, what does the correspondent do, and how to reflect it in a paper?" "A: The first author is the person who runs through the whole experiment and makes the greatest contribution in the experiment. He is the author of the first draft of the paper and the main executor of the experiment. The correspondent is the person in charge of the project, an academic authority, responsible for the project design, funding and experimental design. People who are convenient for academic communication will be marked on the upper right of the correspondent in a paper. Look at your scientific research skills. Fortunately, I checked it before the exam.

Then the teacher asked: what principles should be followed in the placement of drugs in the laboratory? It's just a bunch of reagent bottle. How can I put it? A: I have a lot of balabalabala, and I haven't talked about the key points. Then the teacher spoke. You gave several examples to answer: (At this time, the teacher was also reaching out and pointing out the number for me. Products that can be decomposed at high temperature should be kept at low temperature, liquid and solid products should be kept separately, products that are easily decomposed by light should be kept away from light, and drugs that are easy to react and volatile should be kept separately. A few days ago, there seemed to be an accident at the Institute of Chemical Engineering. A classmate's hand was injured in the experiment. This is a chemical safety issue, which needs attention.

Then the next teacher came. Q: Do you know graphene? What's the use? A: The discovery of graphene was awarded the Nobel Prize (brain drain in Russia) by two Russian-born scientists from Manchester University in the UK a few years ago. In layman's terms, it is a thin molecular layer adhered to the surface of graphite with adhesive tape. (The teacher spoke: Yes! That's it. ) Its hybridization mode is sp2 or sp3 (teacher laughs), carbon atoms are closely arranged, and the speed of electron movement is 1/300 of the speed of light, so it has high conductivity and low resistance, and is an ideal electrode material. The teacher asked again: Did you prepare these in advance or have you seen them all before? This is what I used to know by reading the headlines. The teacher nodded his head.

The next teacher asked again: This is an open question. Say as much as you can. Do you know what is the most used energy in our country? This teacher works in energy, and Mr. Zhang Zhengguo seems to be the dean, which I saw on the exhibition board when I signed it later. ) A: Coal, "Is that coal renewable or non-renewable? What is renewable or non-renewable? " A: Non-renewable energy takes tens or even hundreds of millions of years to form. After all, the energy on the earth comes from solar energy, for example, it can be generated in a short time. What I said may not be accurate, please pay attention.

Then he asked, "Do you know what renewable energy is?" A: Solar energy, biomass energy, and then stuck for three seconds. The female teacher in the middle began to sit still and began to prompt, "Is wind energy a renewable energy source?" A: Oh, oh, oh, yes, there are also wind energy, nuclear energy and hydropower. Then the boss began to ask, "Do you know what role solar energy can play besides converting into electricity?" A: Because my undergraduate major is dyeing and finishing, our teacher uses TiO2 _ 2 to support photocatalytic oxidation dye decomposition to reach the sewage discharge standard, and solar energy can be converted into kinetic energy and driven by light (in fact, it can also be said that the team of Nankai University designed and manufactured a light-driven material last year, and the light-driven material can travel 0.8m, which was seen in the headlines, but was not mentioned at that time).

Then the teachers nodded and said, your interview is over, you can go. Then I left the interview group and said, thank you, teacher. I made an appointment with a teacher to join his research group in advance, and the answer he gave me was to wait until the second interview, which obviously meant no! But he also gave me some information. "If your interview teacher explicitly asks you a few open-ended questions, you will get extra points if you answer well, and you will not get less points if you answer badly, so your interview score will not be lower than 90 points." In this way, you can grasp the results of your interview and don't make the atmosphere of the conversation particularly embarrassing. Remember that teachers are human beings, as long as we show our due respect, don't think that we are just high above others and difficult to get along with. In fact, the most important thing in an interview is the interviewer, not your knowledge. You should also say more about what you can't say, express your opinion and say more about what you can say. )

Suggestions for the interview

Be familiar with the documents of the re-examination strategy before the interview.

The basic questions asked are similar, and they remain unchanged for several years, just like graphene last year, and there are frontiers in science and technology. For example, gravitational waves were the hottest issue last year. Although molecular machines (Nobel Prize) and topological phase transition are not involved this year, we are still prepared. It's good to get in touch with science and technology news at ordinary times, and you don't need to know too much. Of course, it is best if you know it thoroughly, so that you can stand the doubt! The news suggests reading it well before going to bed every night. This is very important to broaden your horizons. When the teacher asks, you can talk about it in Kan Kan instead of completing this sad sentence.

In English, everyone is similar. The last topic is free to play. You should prepare your lines in advance, such as how to introduce your friends, your favorite teachers, your plan for the future, how to realize it, and how to become a qualified chemical engineer. These can be prepared. In addition, there will be an experiment that you are most familiar with a few years ago, which is related to your undergraduate major and does not necessarily require the experiment of chemical engineering principles. You can also prepare for this. Although you didn't pass the exam this year, 18 may not be required. The preliminary test results are out. Do you need a tutor?

My major is chemical engineering. Can I find another teacher? After the initial test results come out, you can find a teacher, because the teacher also likes to apply for his graduate students as the first choice. You can say hello first, meet at school first, and give the teacher some small gifts. It's not surprising that many people are polite! I brought a little tea to my teacher at that time, and I could get some news from my teacher (as mentioned above). In fact, the Institute of Chemical Technology basically has no requirements for majors. As long as you participate, almost all teachers can choose. For example, a chemistry student chose an organic teacher, and I also chose an applied chemistry teacher. This is your research direction.

I also came from the postgraduate entrance examination. I hope some of my words can provide you with useful information. My initial intention is to let everyone pass the exam and fulfill their dreams. I am also a merit! Remember to invite me to dinner when you pass the exam! Finally, in the words of Ge, "You are not only who you are now, please remember what you are." I'll wait for you at Nanjing University of Science and Technology! The oral English test will make you read a sentence and then translate it. The teacher may ask some questions. Asking questions in English is to test your English ability. As for preparing for self-introduction in advance, I think it is dispensable, because at that time the teacher went straight to the subject and asked questions directly.
