Write an application to the Principal of your school requesting him to allow you to change your subjects

Madam,

I have come to the conclusion that it was a mistake on my part to have taken Commerce with Mathematics as my subjects. 1 am an above average student and yet I feel I should change them for Physics, Chemistry and Engineering Drawing. My subject teachers have no objection to this change.

I shall be grateful if I am allowed this change as early as possible.

Thinking you

Yours obediently,
