There is a certain relationship, and the difference in IQ will really affect the study of mathematics. But as the saying goes, diligence can make up for mistakes, and you will learn well if you work harder. I don't think IQ can deny a person's ability. Everyone has different characteristics, so they have different advantages. Some people have good spatial imagination, and some people have strong logical and abstract thinking, which are the abilities needed by mathematics. The key is that the landlord should not doubt himself, but recognize himself and explore his potential.
In high school, I think the main thing is to listen carefully in class, do my homework carefully after class and add some questions, so I will definitely learn math well. In addition, we should sum up some ideas and methods to solve the problem.
