The review that we had one week ago regarding my assignment grades resulted in an A. However, you put the wrong grade on Classroom. It should be an A. Thank you.

Subject line: ENG 111: Assignment 2 Grade

Dear Dr. Jones:

When our Assignment 2 essays were returned in class last week, I had received an A according to the grading rubric. However, I noticed today that the Assignment 2 grade listed in Classroom is a B+. I just wanted to confirm which grade I received. If my grade was an A, could you update this information on Classroom for me?

Thank you for your time and any clarification you can provide.

Sincerely,

John Smith
