This year I have sought admission in XIth class in your school. I had intended to take Maths initially and with that aim I had filled up Maths group. But now I feel that I had made a mistake, Biology group would be better for me. Hence, I fervently request you to allow me to change to Biology group.

Hope you would sympathetically look into my matter and allow me to change my subjects.

Thanking you,

LETTER 

______________________________________

Write a letter to the Collector requesting him to ban the use of loud-speakers.

31, Ashish Nagar,
Katni
1st April, 20 ….

To,
The district Magistrate,
Katni

Subject: Ban on the use of loud-speakers

Sir,
I want to draw your attention to the nuisance caused by the use of loud-speakers. I am a student of high school and my examinations are near. It is a time when all the students are busy day and night preparing for the examinations. Their success depends upon the proper use of their time and the concentration of their minds. It is regrettable that majority of the citizens do not realise the importance of this time for ! students. They enjoy full liberty to use loud-speakers at their highest pitch to celebrate every occasion that comes to their hands. The result is that we are unable to make preparations in the right way. I therefore request you to kindly impose a ban on the use of loud-speakers for the period of Board Examinations and punish those who are found guilty.

Thanking you.

Yours faithfully
Raj Malhotra
