Note 1) Homework must be ready for peer grading and discussion in class on the first listed due date. It must be turned in for a final grade on the second listed due date. Peer grading will be 1/5 (20%) of the homework grade.

Note 2) Homework solutions are usually available one or two class periods after the due date. Click the "returned date" on this page to access the solutions. If the "Returned" date is not shown or is not a link (is black, not gold) then the solution is not yet posted. Check back later. If you click the link and get a login screen instead of the solutions, log in using your usual courses@dordt username and password. Then use the back icon (or alt-left-arrow on the keyboard) twice to get back to the link on this page and click the link again. The link only works when you are logged in to courses@dordt.

Note 3) Problems sets shown above with no "assigned" date are tentative. More problems might be added, expected due dates might change, but problems shown will eventually be assigned.
