H1N1 Note: Those who have an influenza-like illness, with symptoms such
as cough, fever and sore throat, should stay out of close contact with
others and not come to work or class to reduce the spread of infection.
In order to accommodate students' absences due to flu-related issues,
make-ups for quizzes and exams will be offered during normal office
hours and at other times when necessary.
You will be
able to check your homework and exam grades at Score Reports,
which
is the Math Department's gradebook program. This will be
available
beginning approximately two weeks into the semester. All your
h/work,
quiz and exam grades will be posted there. You will be prompted for
your NetID
and NetID password after following the Score Reports

have been
correctly reported and tell me promptly about any errors. You are
responsible for keeping all of your graded homework and exams so that
any discrepancies
