1). I didn't do well in the exam this time, and I was also deeply stimulated. The main reason for my reflection is that my learning attitude is not correct and I don't realize that the motherland is advancing by leaps and bounds and needs a lot of talents. Small bludger can't bear the heavy responsibility of construction. 2) A firm grasp of the concept is the key to learning, but usually the concept is not well understood, and the exams are all out. 3) There is another important problem in mathematics learning: to turn knowledge into skills, we must practice more at ordinary times, broaden our horizons, and enhance our ability to analyze and solve problems, as well as to judge and solve problems. I will definitely do more exercise in the future and change the bad habit of stopping after eating. 4) Learning is also a process of communication. In the future, I will consult my teacher, communicate with my classmates who have studied well, learn from each other's strengths and strive for faster progress.
