Dear Professor Smith,

My name is John and I am currently enrolled in your course. I was wondering if there would be any extra credit assignments available for the semester. I am eager to make up for any missed assignments, if possible. I would very much appreciate if you could provide us with an opportunity to earn extra credit.

Thank you for your time.

Sincerely,

John Smith
