請幫忙以下文字譯做英文~thanks!

Dear Mr. Chan,

I am your student XXX who has been completed the course at the end of August. When I received the school result, I was shocked that it was grading at I, which is (assignment / examination not completed). In fact, I have completed all assigments and final examination. I have been noticed the secretarial department and they adviced me to contact you about the case directly. Therefore, would you please help me to re-confirm the result again? Or something else that affect the result ?

Thank you for your attention, sorry for any inconvenience caused to you.
