Answer:
Respective sir,
I recently applied for admission in your High school and got selected for the arts and culture program. Although I am proud that a popular school like this gave me a chance with their auspicious program. I want to change my course to science and technology.
Sir, I have been a science geek since the beginning and that is area of interest as well as expertise.
My core version is the nano technology, which your school has he best faculty for. I am sure studying in your programmer of nano technology, I will be able to grow very fast.
