Dear Mr. Smith,

I am writing to express my sincere apologies for my recent behavior in class. I deeply regret the mistakes I made and the inconvenience they have caused.

During the computer class on [date], I should have been attending the lesson but instead, I chose to play computer games. In art class on [date], I failed to follow the assignment and only read books instead of creating art. These actions were contrary to the expectations set by the teacher and the objectives of the course.

I acknowledge my mistakes and take full responsibility for them. I realize that my lack of focus and commitment to my studies led to these errors. I should have been more disciplined and focused, but I let my interests distract me from my responsibilities.

To prevent such mistakes in the future, I have decided to take several steps. Firstly, I will prioritize my studies and ensure that I attend all my classes and complete all assignments. Secondly, I will seek help from the teacher if I need it to improve my performance. Additionally, I will avoid engaging in activities that distract me from my studies, such as playing games during class time.

I am committed to making amends and improving my academic performance. I hope that through my efforts, I can regain the trust of my teacher and classmates.

Thank you for your understanding. I look forward to your feedback and guidance.

Sincerely,

[Your Name]
