Sir,

I beg to say that I am a student of class XI in your college. I have offered Biology as one of my subjects. But I feel no interest in Biology.

Now I want to offer Art in place of Biology. Kindly allow me this change. I assure you that I shall soon come up to the level of the class. Thanking you, Sir.

Yours obediently,
XYZ
