Dear grade director:
I made a mistake this time. I thought a lot and reflected on many things. I'm sorry, and I'm very angry with myself, because I broke the iron law of the school. I am also deeply aware of the seriousness of my mistakes and feel ashamed of them.
At the beginning of school, I repeatedly emphasized the school rules and discipline to remind students not to violate the school rules, but I didn't pay attention to what the school and teachers said, what the teachers said, and what the school promulgated. None of this should be. It is also disrespectful to the teacher.
What the teacher said should be kept in mind, and the school rules and school minutes promulgated by the school are urgent in mind. Afterwards, I thought calmly for a long time. The mistake I made this time not only brought me trouble, but also delayed my study. Moreover, my behavior has also caused a very bad influence on the school and destroyed the management system of the school. It also caused a bad influence among classmates.
I will further sum up and reflect on all this, and urge the teacher to believe that I can learn from my mistakes and work harder in the future. At the same time, I sincerely hope that the teacher can continue to care and support me, but handle my problems as appropriate.
