Hello, I volunteered to join the math promotion class organized by xxxxxxx. I hope I can improve myself, exercise myself and make up for my shortcomings in mathematics through it.

Please rest assured that I will study hard in the advanced class and strive to be excellent.

In addition: parents and individuals who enter and leave the affordable housing are responsible, and have nothing to do with xxxxxx.

Please grant my request.

Believe me, I have been in an excellent class for three years. It's all in this format
