Hello, I'm sorry to submit this letter of criticism for failing the math exam. I feel deeply guilty that I didn't get the expected results in this exam. I must be a little sorry for my parents' concern and teachers' teaching. I hereby submit this critical letter to apologize.

Regarding my unsatisfactory mid-term exam results, I summarized the following reasons:

First of all, my learning attitude is not good. In the first half of the semester, because sometimes I don't listen to the lecture in class, I often miss the knowledge points told by the teacher and delay my study.

Secondly, I didn't review in time after class. In the first half of the semester, I have to say that not attending classes can make up for it by writing exercises after class. But for general reasons, I still didn't go back to the cram school, so I didn't have in-depth analysis and understanding of the knowledge points I didn't understand.

Third, I'm under too much pressure. In fact, this kind of pressure is not only imposed by my parents, but also my parents' concern for me. I hope I can get good grades and have a bright future. But I failed my parents, so that I would feel nervous during the exam, and my hand holding the pen would tremble because I couldn't do the problem.

There are many reasons for my poor performance this time, but in the final analysis, the fact that I failed in the exam is already in front of me. While reflecting on my mistakes, I have focused on the next exam. Here, I hand in this letter of criticism for failing the math exam and beg the teacher's forgiveness.

Example 2: Dear xx:

Regarding the problem of failing in the math exam, I hereby submit a written complaint about failing in the math exam, deeply reflect on my mistakes, give you a truthful guarantee, and put forward sincere rectification measures to make up for the mistakes to the greatest extent.

Looking back on my mistakes, I had a serious problem of weariness in the final stage of mathematics study. Once, I almost didn't listen carefully in math class, which led to many courses' knowledge points' not being mastered. In the end, I failed the unit math exam and got the lowest score in the class.

I feel extremely ashamed of my mistakes, which fully exposes many problems in my mind, such as relaxing myself and slacking myself. There are many problems, in the final analysis, I am not mature enough to fully realize the importance of learning mathematics.

Here, I assure you:

1, I will definitely improve my full understanding of the subject of mathematics in the future, and strive to improve the quality of my study, so as not to be biased or slack.

2. I will try my best to get into the exam, study math seriously, improve my math scores, and strive for good results in the next math exam.

3. I must take this as a warning, reflect on myself, reposition myself, and strive to become a good student with all-round development in morality, intelligence, physique, beauty and labor at an early date.

In short, I am willing to accept your supervision!
