Write an application to your principal requesting him to remit your fine
Most respectfully I am to say that my English teacher has fined me for not taking the special test. He thinks that I did not take the test intentionally. The fact is that I was suddenly taken ill just a day before.
As my parents were away to a marriage and there was no one in the house to deliver my application, I could not even apply for leave.
I shall feel obliged if you kindly remit the fine of Rs. 50/- imposed on me by the English teacher.
