How do I articulate my grade dispute in a letter of complaint (student grievance)?
Dear Committee,
This grade dispute seems like a simple math error. As shown on the
attached syllabus, the grade is 85% exams and 15% worksheets and
responses.

On the exams, I scored 76.5/85, which is a 90% (A)
On the worksheets/responses, there were three worksheets and I received a check mark on each of them. To my knowledge, no other
factors counted toward this part of the grade. Further, my class
participation was exemplary, so if there were other factors, they
should have been in my favor.

When I asked the professor about my grade, he said that 76.5 was a B
and he had used the worksheets and responses to &quot;bump me up&quot; to a B+.
But this is not mathematically consistent; 76.5/85 is an A, and the
professor admitted the worksheets/responses would &quot;bump me up,&quot; not
down. I never received any evidence or justification for why my grade
would be lower than 90%.
Regards,
Name
