Diligence and talent complement each other in learning. If a person works hard, but he has no talent in this field, then he can't reach the first and second heights no matter how hard he works. If a person is very talented, but he doesn't work hard, it is difficult for him to get the first and second place. So in learning, talent and hard work must be at the same time. Only in this way can you become the first and second. One of my classmates is such a person. He scored more than 660 points in the college entrance examination. How did he get such a high score? Let's talk about his learning methods. First, I'll introduce him to you. He is a very diligent person and very talented. He can listen once in class and do many problems after class. I remember I didn't do much at the age of 53, and he was almost finished. I admired him at that time, because like me, I usually have to listen to it several times in class, and he only needs to listen to it once to understand it and do it after class. In addition, he is always willing to give lectures to others, because he thinks that if he gives lectures to others, he can deeply understand this part of knowledge in his own mind, so that even when he gets there, he will not forget that giving lectures to others is the best way to test his learning.
To sum up, this is what I think, why some people can get more than 140 points in math exams, thanks to their cleverness and diligence.
