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.
