Write an application to the principal of your college to seek permission for a study tour.

Application 

I beg to say that I am the student of first year. My roll No. is 504. We, the students of first year have planned to go to the Derawar fort with our Professor of History to witness the historical importance of Derawar Fort. It will increase our knowledge of history. Sir, so you are requested to grant us permission for a study tour and also arrange for transport for us. In my opinion, it will be helpful in increasing our knowledge.
