Dear Sir/Ma’am,

I (Name) student of (A Levels/Grade) feeling sick since last week and now my sickness doesn’t allow me to attend classes because of flue and cough (State your situation). I request you for leave for at least three days (as your requirement). If I will require more leave I will inform you and send your application in email for leave after the medical checkup. I hope this rest will make me perfect for studies and again I will be the best student in my class.

Thanking you,

Sub: Leave Letter for School

Respected Dean!

Hope you find this in good health. Sir my mother has been discovered with cancer a few days back and now her health is getting worse and worse with each passing day (State your situation). If she would have lived in the same city I would have taken her to my home since she lives in another state I would have to go there for a few days to sort everything out and then mover her here with me.

In order to do that it would require of me to spend a few days there which would only be possible if you can grant my application of leave that I am presenting with this letter. I shall be very thankful to you.

Regards,
