You can subscribe to the entire set of movies and view them as podcasts within iTunes. This saves the movies to your disk so they're always available for immediate viewing. To import the movies into your Podcasts playlist in iTunes click the subscribe button below. See the Quicktime page for more information.


The dates shown are DUE dates. You should start work on each assignment around 10 days before the assignment is due.


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.
