My grades in this exam are not very satisfactory, which has a lot to do with my usual efforts. Recently, I have been a little playful and neglected my study. What's more, I am partial to mathematics, and I will be very tired to learn. However, I will never give up. I will try my best to refuel in peacetime and make up for the recent class. Ask your classmates and teachers with an open mind, never let go of the questions you can't, increase the training of doing the questions, and find the rules from them. I believe my math scores will improve. I promise I will improve my math scores in the next exam!

Dear teacher:

Today, I write this letter of guarantee to you with guilt and regret, to show you my deep understanding of the bad behavior of being addicted to computers and my determination not to be addicted to computers.

As early as when I set foot in the school, the teacher repeatedly stressed that all students in the school should not be addicted to computers. But my lack of understanding of mistakes led to such a thing. While writing this guarantee, I really realized the seriousness of this matter and my mistake. Third, my behavior affected my grades and damaged the image of the class. As students, we should obey the teacher's teaching, obey the teacher's arrangement, respect the teacher and attach importance to teaching. But my performance has brought a bad head to my classmates, which is not conducive to the construction of the school's style of study. How much the teacher cares about us and loves us! But I have given my teacher trouble, trouble, so I will abide by the regulations of the school, listen to my teacher, fully understand my teacher's requirements, and ensure that similar things will not happen again. I hope the teacher can give me a chance to turn over a new leaf. Through this incident, I deeply felt the teacher's behavior and emotion that ruined my study style, which made me feel very guilty psychologically. I am very grateful to my teacher for his profound education.

I promise that I will never be absent from class for no reason in the future, and similar situations will never happen again. I sincerely accept criticism and am willing to accept it. For all this, I will further summarize and deeply reflect, and sincerely ask the teacher to believe that I can learn lessons and correct my mistakes!

Now, the most important thing for me is to study. There is great competition in learning. I should study hard every minute, but I am relaxed at this time. ...

I feel so guilty!

Let's talk about how severe the exam form is now, and then what your goal is. Properly ambitious. Then explain that you want to enter a good class, and say what do you think of the learning atmosphere and how fierce the competition is.

Here, I promise my teachers, just like my parents:

1. No longer addicted to computers.

2. Seize the time, study hard and strive for ideal results.

3. Strictly abide by the rules and regulations of the school.

If I violate the above guarantee, (make up some punishment yourself! )

Sponsor, your student XXX

Date, year and month

I hope a little revision and supplement can help you, and I wish you progress in your study!
