  Note: The due date was originally erroneously shown
  as 8/26

Note 1) 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 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 2) 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.

Note 3) If you are having difficulty reading the latest version of this page it may have to do with your browser's cached memory. Read this note on cached pages to solve the problem.
