Looking back on my own mistakes, I found that I was lax in my learning attitude in the previous stage. Sometimes I didn't listen carefully in class, didn't review the text after class, and didn't master some knowledge points well, especially some basic questions didn't go through in-depth analysis and research, which led to the fall of a large number of basic questions in my mid-term exam, which led to such painful consequences!
This mistake fully exposed my lax and laissez-faire attitude towards mathematics learning, and did not put enough energy into mathematics learning, which also showed my lack of curiosity and self-motivation to some extent.
Now, the mistake has appeared, and I no longer defend myself. I will only face it calmly and give you a solemn promise: from now on, I will pay special attention to math learning, try to correct my attitude and behavior mistakes, firmly establish the concept of "math is very important, math must be learned well", and strive to get a good score higher than the class average 10 in the final exam this semester.
Finally, please forgive me for the time being and let me behave well in the second half of the semester.
