This page shows the dates that assignments will appear among your current WebAssignments. Once an assignment has appeared there, WebAssign will show you the due date for the assignment. All old (past due) assignments also remain visible within WebAssign.

Be sure to check the news page several times each week!

If you live more than 50 miles from campus and wish to attempt to negotiate special arrangements for taking tests without coming to campus, you MUST be enrolled via distance education (in MA 114 Section 601). All students in MA 114 Section 006 are expected to take their tests on campus.
