How to write an application to the Principal of your school for the change of section ?

To
The Principal
Cambridge School
Noida
Sir,

I am a student of class IX (A) in your school. My cousin sister Lata is in Class IX (B). We read in same class but in two different sections. As we are staying in a joint family, we all live together, study together. We prepare our home task together. We also read a few common help books. But as we attend the class in different section, sometimes the home task also differs and my father takes much pain while teaching us in our house.

I therefore, request you to kindly allow us to read in one section, so that we may study and do home-task together. I shall very much grateful for this kind favor.

Your obediently
