Which is the most difficult course you take in college?

Majoring in physics, the most difficult thing I went to was quantum field theory... Originally, I was doing atomic physics, but I wanted to enrich my academic system, so I learned quantum field theory before I laid a good foundation, and the peskin used in the textbook had a lot of writing errors on it, but because it was too difficult, I didn't know if I didn't understand it or wrote it wrong. So I often end up reading 10 pages of textbooks in one day in the library.

But the content is really enlightening, and it can be regarded as one of the turning points in my understanding of physics! To understand this course, you need to master the basics of advanced mathematics, linear algebra, college physics, mathematical physical methods, quantum mechanics, and crystallography, plus a lot of time to understand how he derives it.

The most terrifying thing is that for children of functional materials, solid state physics is a basic course. So there's a bunch of completely incomprehensible things to be understood by solid state physics. <>

At China Pharmaceutical University, the most collapsed undergraduate is pharmacology!! Nearly a million words of textbooks have to be memorized everywhere!! Memorize it!!

Memorize it!! The whole book is unfocused, and every corner can be tested (in fact, it is really a corner thing). And ......At that time, it was only a week, and the last subject had just finished the hard back medicine one hundred and eight generals (all the one hundred and eight structures had to be remembered to look at the name and draw pictures......And that's not even counting synthesis and basics in pharmaceutical chemistry).

At least 800,000 words a week to memorize, and it is not very logical and connected, most of them still have to rely on hard memorization, so the devilish recitation from opening the eyes to closing the eyes lasted for a whole week, and it was really memorized, but it is still in the shadow today. Since then, the perception of endorsement has reached a new level. The driver's license theory test only brushed the question bank for 2 hours, and the next day was a full score; The standard answers to the first 50 questions in the political exam took only one day to memorize more than 90 in one day; Go to eat rice noodles and say that whoever can repeat an advertisement of the host just now can get a prize, and easily win two sets of 60 yuan free coupons for rice noodles across the bridge......Hehe, these little cases are also recited?

Power electronics, microcontrollers, mechanical drawing,

Hard work pays off, no matter how difficult the problem is, as long as you are willing to pay patience, hard work will definitely be overcome!

First, the mentality must be good

Don't think you won't get in. I don't know if you have such an experience, that is, you obviously don't want something to happen, but it just happens. For example, when I was a student, when the teacher asked a question, I silently recited in my heart that it was not me or me, followed by the familiar name.

When I performed on stage, I thought that I must have memorized it, but I forgot the content of the performance. I don't know if anyone else has had this experience, but I have a lot of them anyway. So don't have the mentality that I can't.

Second, the exam is focused on the difficult points.

As long as there are major difficulties in the exam, then you must know where the focus and difficulty of the exam are, have a goal to study, and allocate time reasonably. The energy and time for the key and difficult points account for the majority, and the rest is reasonably distributed.

Third, formulate a reasonable target plan.

The process of preparing for the exam is not achieved overnight, it is a long-term process with a reasonable goal plan. Otherwise, look at this today and look at that tomorrow, if it is not systematic, you will definitely not be able to learn well. Because each course has its own system, continuous learning according to its system is definitely rewarding.

Fourth, do the question.

The test is the proficiency of the knowledge points. If you don't do the questions, you will never be proficient. Do more questions and read more wrong questions. Wrong questions are very important, especially the same type of wrong questions, which means that the corresponding knowledge points have not been mastered well, in this case, you should go to the book or see the teacher, and then do the questions.

Fifth, selective renunciation.

If you don't have enough time and limited energy, you have to give up selectively. It's good to pass the exam. There's no need to chase high scores.

When the time is tight and the task is heavy, the kind of exam that only takes the exam once in a few years, and the one with a small score can give up and give up. Remember, the goal of a level exam is to pass the exam, not to get a high score, and competitive exams are a different story.

No matter how difficult a problem is, it's built by a simple model. Break down the questions, then open the book again and see how each question in the reference book is answered. These problems can be subdivided into other smaller problems, so that one central problem has three or five sub-problems, and each sub-problem corresponds to three or five sub-problems, and you have a framework for a problem.

And to solve this problem, it is to summarize from the bottom knowledge upwards, layer by layer, until you know the central problem well!

As a graduating college student,I want to tell you: "There is nothing difficult in the world, but I am afraid of those who have a heart." Have confidence in yourself, but also pay attention to this course, and don't be afraid to learn it badlyCollege is different from high school, if you don't have such high requirements for yourself, even if the subject is very difficult, then can't we set a goal of not failing the course?

Persist in studying hard for a semester, and the final exam will never be much of a problem.

Learn to preview and review, and don't be a passive person in learning, but try to become an active person。When I was a freshman, I was terrified of advanced math, and I spent more than two hours every night reviewing what I had previously taught and what I was going to talk about next. I knew that I was not good at math, and I was also very bad at math in the college entrance examination, and I was afraid that I would not understand it in class.

But I found that this kind of learning was really effective, at least I didn't feel like I was listening to a book when the teacher was lecturing, and it didn't take so much effort to learn.

Don't stick to the teacher and the class, listening to the class is very limited. Sometimes what the teacher says can't be done, you can learn it yourself。Some university teachers take a ppt to read there as soon as they are in class, which feels really boring, especially the course is already difficult, the teacher is still in the clouds, or the teacher's teaching style is not acceptable, then you can listen to other teachers' classes, and now the network conditions are so developed, such as MOOCs, free courses at station b can be a good choice.

At the same time, I also look for reasons in myself and summarize more methods, which will also have a certain effect.

Don't think you've worked hard enough, the effort spent is directly proportional to the amount of time you have mastered the knowledge。When I was a freshman studying advanced mathematics, I spent four or five hours a day. You can't be lazy in your studies, and my advice is to try to find people who are professional in this major or in this course when possible, such as teachers who teach you this course.

You can ask him, "Hello teacher, I want to learn this course well, do you have any books or course recommendations?" "When I was a sophomore, I was extremely miserable to take a difficult course, that is, my teacher recommended me an online course, and I did well in the final exam, so I am very grateful to my teacher.

The last thing I want to tell you is that "everything is difficult at the beginning". To do it now, to act, you must persevere. Don't think too much, the accumulation of quantity has reached a qualitative leap, a little bit a day, a day or two days you may not feel anything, but two months and a half a year, or longer, you will feel your progress.

You have to overcome it slowly, start from small things, and start with persistence.

Read books and check information on the Internet, and focus on the key points of the difficult points to understand it, and it is best to do the next question by yourself to feel it. If you don't understand, you can also ask your classmates and teachers to discuss it together.

Even if it's difficult, you have to spend more time learning, and if you don't understand, ask your classmates and teachers.

1. Mathematics. Mathematics (MATH) is the study of concepts such as quantity, structure, change, and spatial models. Through the use of abstraction and logical reasoning, it is generated from counting, calculating, measuring, and observing the shape and motion of objects.

Mathematicians have expanded these concepts in order to formulate new conjectures and to establish rigorously deduced truths from appropriately selected axioms and definitions.

2. Physics.

Physics is the natural science that studies the structure, interaction, and motion of matter in nature. It is a natural science based on observation and experimentation. Its achievements are of positive significance for human science to understand nature and dispel superstition.

A constant theme in physics is the search for orders, symmetry and symmetry breaks, conservation laws, or invariance.

3. Chemistry. Chemistry is the science that studies the composition, structure, properties, and changes of matter. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

4. Biology.

Biology is a category of natural sciences that studies the structure, function, occurrence and development of organisms, as well as the relationship between organisms and their surroundings. Biology originated from naturalism, experienced experimental biology, molecular biology and entered the period of systems biology.

5. Geography. Geography is the study of the earth, its characteristics, inhabitants, and phenomena. It is a discipline system that studies the interaction between the various circles on the earth's surface, as well as its spatial differences and change processes, mainly including physical geography and human geography.

In college, through my counseling with my high school classmates, I thought:Fine arts, teacher training and law are relatively few professional coursesTarget.

Majors in Languages and Management. Most language majors study two languages, one major and one minor, with relatively few courses; Management-related majors such as tourism management, logistics management, etc., are also relatively relaxed.

Engineering and medicine are particularly tiring in college, and liberal arts and business are relatively less classy. In particular, Chinese language and literature, journalism, and economics and finance have very few professional courses after completing basic subjects.

Feng Shui major, because there are very few people who study this major, and there are few people who understand this aspect, so in the university, there are few students and teachers in Feng Shui, so there are few courses.

First of all, from the perspective of graduation, it is important to complete the credits and pass the exam, so it is necessary to study both professional courses and basic courses, but we can allocate the study time of the two reasonably.

First of all, let's talk about the basic course, which is the framework of basic knowledge in a sense, and the professional course is the height of a certain field, a breakthrough in your basic framework, and it is also the job signboard after you graduate. As for which one is more important, I personally prefer a professional course.

The basic course is similar, that is to say, there is little difference in its main framework structure, of course, there are individual differences, but the professional course is a signboard, when you are employed, your work cannot be involved in all aspects, it must be emphasized, that is, the strengthening of a certain ability, which is the importance of the major.

Of course, for those who are studying a major that is not necessarily your future field of work, professional courses are not so important, and for these students, basic courses and professional courses depend on their own preferences to determine your focus. Similarly, the importance of professional courses and basic courses is also different in different majors, and for those majors with strong practicality, practical basic courses are even more important.

I think it's still important to take professional courses, because professional courses are directly related to the problem of getting out of school and entering the society to find a job.

Specialized courses. After all, professional courses are your future housekeeping skills, how to earn money and eat if you don't learn them well, but basic courses such as advanced mathematics cannot be ignored.

Professional courses are important because they can help college students gain a good knowledge base during their time in school.

Specialized classes are important. Professional courses are courses related to one's major, and they are also the courses that can improve one's ability the most.

Higher Mathematics was ranked first in the number of nominations and left the other subjects behind by a landslide. As we all know, high mathematics is a "tree", but there are many people hanging on it.

It is difficult to go to the sky, there is always a knowledge point that can make you doubt your IQ and make you collapse.

Since elementary school, math has been a nightmare for many people. When it comes to university, whether it is science and engineering, or social sciences such as economics, advanced mathematics is a compulsory course, and you can't escape it.

Even, this kind of "mathematical anxiety" has become a kind of special academic anxiety disorder, and it is also a hot issue in the research of psychologists. And it's not just that you're afraid of math and you're afraid of learning math, it's common all over the world. In addition to advanced mathematics, courses such as English, Economics, Probability Theory, Physical Education, Linear Algebra, Mechanics, and Western Economics are among the best.

In addition, pharmacology, biochemistry, electromagnetic fields, signals, and systems must also have names.

From the perspective of subject categories, college students have not only professional courses such as advanced mathematics, economics, and criminal law, but also public courses such as physical education, Mao Xuan, and Ma Yuan.

Although college students think that they have strong "independent learning ability", they have little confidence in "foreign language ability", "professional knowledge", "mathematical calculation ability" and "practical ability".
