Write a letter to your younger brother reprimanding him for having neglected his studies and advising him to be more diligent.
D-20, Green Park,
October 4, 200__ Dear
Yesterday we received your report card from your school. We are disappointed to learn that you have failed in almost all the subjects. Also your house incharge has complained that you keep the company of bad students.
Mom and Dad were very much pained to learn all this as they have high hopes from you.
I advice you to study sincerely and leave the company of bad students. I am sure that if you study with sincerity you will come out with flying colours. If you need to engage a tutor, then do so.
I hope you will heed to my advice and do better in the next examination.
Your elder brother,
