Dear sir/mam,

Myself a student of polytechnic wants to request you to postpone the early semester exams which are held too early due to elections. Sir within a period of only 2 months it is too difficult to prepare for the exams. Sir Please i humbly request you to give us at least 1 more month to prepare for the upcoming exams.
I hope my request comes to light soon.

Thanking you,
Yours sincerely.
