Dear Mam, 

Please ignore my previous mail regarding leave application and consider this mail.
This is to inform you that I have to appear for my exams in the month of June 2019. So, I would require some leaves during my exams in June on the following dates-
05 June 2019 Full day leave, 
06 June 2019 Full day leave,
07 June 2019 Full day leave,
10 June 2019 Half day leave,

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
