Sir,
Through the columns of your esteemed newspaper, I would like to draw the attention of the concerned authority on the lack of seriousness in the teachers regarding teaching. The teachers do not focus on explaining the chapters rather they emphasize students on mugging up things. In my school, XYZ public School, this issue is very common. The parents have already complained to the school authority but the complaint went into vain. I hope that through this piece of work, the issue would be soon looked up and necessary steps would be taken as soon as possible.
Thanking you in anticipation.
