First: Please don't be discouraged!
I tell you, I am an older graduate student who has never been to high school and has almost no high school foundation. Although I have graduated from college! I spent two whole years preparing math and English and reviewing at work. I studied math with a guy named Wang Houxiong in high school. If you don't understand, I'll get a tutor! However, there is still a difference between the level and the effect of step-by-step intensive training in high school. When I started to look at high numbers, I found that even the simplest trigonometric function could not be solved. So put down the high number and look back at the high school foundation.
Second: the goal!
A person's goal is a necessary prerequisite for your success. If you want to go to an ordinary school. Then maybe 80 or 90 points will be enough. Then see how much foundation and effort you need to achieve this goal! My goal is very high, so I am prepared!
Third: read the book carefully and do the questions carefully!
The concept of the book and the topic after class have been certified once. Don't skip over what you don't understand, but try to understand it yourself. Watch the video, ask the master and find the information! Read the book regularly for more than three times, and the overlapping problem will be consolidated irregularly for more than three times! Prepare more counseling books and videos! Every book has a different method, and some topics you don't understand may be understood in the explanation of one of them! Ha ha. . .
Fourth: the speed and method of solving problems.
Foundation is the key to solving problems quickly. When I was working on a project myself, I found that many obstacles to my speed were my unfamiliarity with basic knowledge and methods, and these basic methods all originated from your high school foundation. Because you think it's the same for everyone to study advanced mathematics. Why do some people learn fast and well, while others learn slowly? The reason is not IQ or hard work, but the foundation. So, don't envy others for doing well in the exam, because others have a better foundation than you!
For example, in the past two days, I have made a topic, that is, the double integral is changed into the order integral, and a trigonometric function is encountered, which is actually very simple, but I haven't even mastered the conversion interval, and it is useless to use the property theorem of high numbers. A little problem has stuck with you for a long time. When I was reading the book Examples of Infinite Series, I found that factorial operation could not be solved. I will put it aside and study how to solve it when I have time. Fortunately, some students told me their high school operation methods before, and it took 1 hour to pass! I will write down my own process step by step, and I will use this method directly next time I meet it. Let me sum up why I did something wrong. What's wrong with the wrong method? Clean it up and find someone to solve it next time! I will prepare a lot of question cards regularly and go to a math expert to answer them every month! You can ask your classmates and teachers directly at school. Envy! Ha ha. . .
When doing the problem, you can read an example first, then do the second one after understanding it, and write it yourself according to the above ideas. If you can't write it, just compare it, which is impressive. If the method is different, summarize it yourself. Generally, there is only the problem-solving process in the tutorial book, and there are no thinking steps. At this time, you will build it yourself! When I found the topic very complicated, I wrote down my thoughts step by step. For example: double integral, 1, drawing according to the topic expression; 2, calculating the image intersection point; 3. According to the characteristics of the graph, choose an appropriate integration method, which is X before Y or Y before X; Do you need to convert polar coordinates? What are the image characteristics of converting polar coordinates? 4. Write an integer field; 5. Write the expression of double integral. 6. Calculate double integral (the basis of indefinite integral and definite integral)
Fifth: Face difficulties with confidence!
You will find that although I haven't been to high school and my foundation is poor, I still have confidence in my learning ability. Of course, this stems from my junior high school, and my grades have always been the top five in my class! Mathematics once passed the third place in the whole school! Then I went to a middle school to participate in the selection, and I unexpectedly won the first place in the school. Fortunately, I was unlucky and didn't go to the junior college. Otherwise, I can't go to college! Ha ha. . .
Secondly, I'm ready to suffer for a long time. I won't stop until I reach my goal! So, I hope you can stick to the postgraduate entrance examination!
Finally: I hope my words will help you. Come on! . . .
