Dear Mam,

This is to inform you that I have to appear for my exams in the month of June 2019. 
So, I would require 7 days leaves during my exams in June i.e. from 5th June to 11th June however, I would be available for any urgent assistance if required.

I request you to please sanction me leave for the above mentioned period.

Thanks & Regards
Rahul Aggarwal
