There's a separate website for online inquiry questions. These sites are not required reading, only suggested reading, and no one is ever tested over them. From time to time, however, students may be given assignments involving one of these sites. Peruse them at leisure. You can probably do OK to read it once, although you may want to refer to it from time to time.
Some people like to follow the syllabus closely, so it's set up to enable that.
This means you better start coming to class. It also posts your final grade before the Registrar sends them out in the mail. Be patient on the grade postings, as I sometimes wait until weekends to update them. If you don't like your grade on something, please don't keep resubmitting the same assignment over and over again in hopes that one of them yields a higher grade. Just move on to the next assignment.
