How to write a critical letter when the photos of the party class are submitted late

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 bad influence on the school, destroyed the management system of the school, and also caused a bad influence among my classmates. Because of my own mistakes, other students may follow suit, affecting class discipline and grade discipline, which is also a kind of destruction to school discipline, a kind of harm to teachers and parents who have great expectations for themselves, and an irresponsibility to other students' parents. Every school wants its students to achieve excellent academic performance, develop in an all-round way and establish a good image, which also gives our school a good image. Every student also wants the school to give him a good learning environment to study and live. Including myself, I also hope to have a good learning environment, but a good learning environment depends on everyone's joint maintenance, and I made a mistake this time to destroy the good environment of the school, which is very inappropriate. If every student makes such mistakes, there will be no good learning environment, so it is also appropriate to punish students who violate school rules. I thought a lot and realized that I had made a serious mistake. I know that I should pay such a big loss for my mistake, and I am willing to bear the responsibility that I can't afford, especially as a person who is educated in a key university, I should bear the unshirkable main responsibility for this mistake. I sincerely accept criticism and am willing to accept the treatment given by the school.
