Write your father requesting him to permit you to engage a tutor (sample letter)

My dear father,

I am feeling that I cannot pull only with the class-room studies. I feel weak in mathematics. I need extra coaching for that.

So, I request you to allow me to engage a private tutor. One of my school teachers is ready to coach me. He will charge Rs. 300 per month.

Please send your consent and money, so that I may start taking coaching.

Your loving son
