Teacher xx:

I am full of guilt and shame to write this letter of criticism. As a representative of math class, I should take responsibility, get good grades in math exams and set an example for my classmates. But I didn't do it. I owe my teacher's hard work. I feel sorry for the teacher. I know this is all my fault. My mistakes are as follows:

1. The main reason for not doing well in the exam is not paying attention in class at ordinary times.

2. I usually do my homework, run errands, and have no good habit of previewing before class and reviewing after class.

Because our team didn't pay enough attention to the exam, we were very proud and didn't review well.

4. No sense of responsibility, no good class representative role model.

I am usually rambling, and the teacher didn't listen carefully.

These are the reasons why I failed the exam. In order to make up for this mistake, I made a plan:

1. Study hard at ordinary times, listen carefully in class, listen carefully to everything the teacher says, and get a satisfactory test next time.

2. Finish the homework with good quality and quantity, and solve the problem in time.

You should compare your attitude towards learning, regard learning as fun, and don't be afraid of suffering. The so-called "there is no limit to learning the sea, and it is impossible to move forward."

4. Have a high sense of responsibility, be a good math class representative, and set an example with classmates.

5。 Solve your own discipline problems.

Please forgive me and give me a chance to correct it.
