If you think you deserve more points for your work, then you need to request a regrade within a week after the day the assignment is distributed in class. You are responsible for picking up your copy if you miss getting it on the day it is distributed. Before requesting the regrade, check the solution key (which will be posted on UNM Learn) and state precisely in your claim which step of your solution seems to have been overlooked by the grader.
Each student is expected to maintain the highest standards of honesty and integrity
in academic and professional matters. The University reserves the right to take disciplinary
action, including dismissal, against any student who is found responsible for academic dishonesty.
Any student who has been judged to have engaged in academic dishonesty in course work may
receive a reduced or failing grade for the work in question and/or for the course. Academic dishonesty
includes, but is not limited to, dishonesty on quizzes, tests or assignments; claiming credit for
work not done or done by others; hindering the academic work of other students.
No Make-up Policy
No late homework will be accepted. A student is allowed to submit homework by email in a SINGLE PDF file.

In accordance with University Policy 2310 and the American Disabilities
Act (ADA), academic accommodations may be made for any student who notifies the
instructor of the need for an accommodation. It is imperative that you take the initiative to
bring such needs to the instructor's attention, as the instructor is not legally permitted to inquire.
