Please come see me often. Call ahead if you are able, since I sometimes have seminars and so forth that take me out of the office. I am happy to schedule an appointment any time. Note, as a rule, I will be out of the office all day after lecture on Wednesdays. Here's a map that indicates how to get to my office.
Students seem to have a hard time finding it.
You must enter at 5620 S. Ellis Avenue and take the short tunnel to the basement of my building. A nice color version of this map is available on the course web page. You grade should reflect the degree to which you have demonstrated mastery of the material of the course. The grading will be based strictly on a comparative numerical score tallied at the end of the quarter. Your numerical score alone will determine your assigned grade.
