Letter to father asking him to hire a private tutor for you

Dear father,
This is the age of competition. I have been a good performer at middle school. I have been securing a position in every term exams.
Now I am at high school pursuing my educational career. I am good at mathematics you know. I performed 100% in my maths papers. But I have little interest in biology. So, here at high school, there is a complete subject of biology with full credit.
The concepts are very complex. Our biology teacher is a good person. He answers every question the students ask. But I could not understand this subject as much. I have tried my best to learn the concepts at school but I could not develop a complete understanding of the subject during my class period.
I am afraid that I won’t be able to perform well in this subject in the final term exams. It will affect my total in the exams. I feel an acute need for special attention to this subject. So, I request you to engage a biology tutor for me.
I assure you that you will reap the fruit of what you invest in my education. I am a responsible student you know. So, I will try my best to take full advantage of my private tutor. It will help me get a good position in the final term exams.
I hope you understand. I am expecting a positive response from you. Please do it as soon as possible as I do not want to lose more time.
Your son,
Your name goes here
