The Headmaster
Dhanmondi School
Subject: Prayer for changing elective subject.

I have the honour to state that I am a student of Class 9 in your school. At the time of admission I took Higher Maths as the elective subject. But now the subject seems to be very difficult to me and I find no interest in it. So I have decided to take biology in lieu of higher math.
I, therefore, pray and hope that you would kindly allow me to took Biology as the elective subject in lieu of Higher Maths and oblige thereby.
Your most obediently,
Md Shamsujjaman.
Class-9, Roll-09
