Write An Application To The Head For Changing Subject In English

The Head of Department
Govt. Degree College

Subject:- An application for changing subject.

Respected Sir, 

  Most humbly and respectfully, I am writing this application to inform your goodself that after the college administration issued combinations of subjects to choose for the next year, I chose the following combination:- 

English/Computer Sciences/Geography

I would like to admit that this was a mistake from my side. Please allow me to modify my current combination and change it to English/Computer Science/Geology. I would be highly obliged and I also have full faith in your sense of justice.

Yours Faithfully
