First of all, the foundation is the most important. Mathematics teaching is a typical link. If the foundation is not laid firmly at the beginning, it will affect the later study. Therefore, at the beginning, even if you keep repeating simple questions, you must first lay a solid foundation in order to get high. Listen carefully and take notes, both of which are indispensable.

Secondly, learning mathematics must be systematic. If there is no gifted brain, we can only rely on systematic arrangement to strengthen memory and improve accuracy and understanding.

Thirdly, according to my personal teaching experience for many years, only by strengthening teaching and practicing more can I improve my math scores. I always think that students can develop their thinking and improve their academic performance only by understanding concepts, doing more exercises and interacting with teachers in class.

If you feel that your IQ is not high, it is a good idea to fully grasp the basic theory, sort out the "wrong problem set" in time and sum up the experience and lessons. Mathematics must not be rigid, but learn to draw inferences from others.
