Notes concerning frivolous requests for regrades
I always encourage students to ask serious questions about a grade.
The reason I require it be submitted the following day is to lower the probability that a frivolous "knee jerk" request is submitted.
This would be a waste of my time. Submitting the request the next day gives the student time to
(1) check my answers that are always posted on my site
(2) check the book once again
(3) clearly think through the logical rationale - which I require them to submit. This rationale
must clearly state the reasons or references upon which the request is based.
