Dear Sir/Madam,
Dear Headmaster/Headmistress,
I have been unwell for the past three days and could not attend school. My doctor advised me to rest before resuming my studies. Kindly grant me a leave of absence for these three days. I will catch up on missed lessons on returning to school. I have informed my class teacher and enclosed a medical certificate.
Thank you.
