Please note the following guidelines for the course:
Grades: The final grade will be determined by homework & quizzes (25%), two midterms (50%) and a final exam (25%). Exam scores are posted on https://learn.unm.edu/ .
Homework: Homework from the previous week is due Monday at the beginning of class. There will be one HW
weekly. You can work together on the homework, but you do need to
write up your own solutions in your own words. To help the grader, please write
your solutions up neatly and clearly (no points for work that the reader
cannot follow- this is also true for exams), and staple the sheets.
The best ten homework/quiz grades only will be counted for a total of
100pts. Please no late homework .
Missed Exams: Make-up exams can be arranged for exams missed with a VALID excuse (illness, family emergency, active participation in scholarly or athletic activities), and ONLY if prior notice is given.
We will accommodate students with documented disabilities. During the first two
weeks of the semester, those students should inform the instructor of their
particular needs and they should also contact Accessibility Services in Mesa
Vista Hall, Room 2021, phone 277-3506. In addition, they should see CATS-
Counseling and Therapy Services;
