Hence I would like to request you to consider my absence as leave.

Thank you

Students: Are you brave enough to let our tutors analyse your pronunciation?

Therefore, I kindly request you grant me a half-day on the date mentioned.

You began your text in the past tense. Thanking in anticipation sounds odd. Especially given the tense but also may come across as expectant.

Date: 25-01-2018
