Syllabus

Grade summary:  Please note:  I had an error in my original spreadsheet formula, and more than half the class had a lower grade posted than they should have.  The corrected formula and correct grades are shown below.  I will file grade change forms by hand, and the correct grade should appear within about 2 weeks.  If I filed the wrong grade for you, I will also e-mail you individually with the correct grade so that you know where you stand.  Sorry for the confusion!
