Every Friday will be a test or a quiz. Each quiz will

average of the remaining quiz scores will be the total quiz grade. If you
miss a test due to illness or for some other legitimate reason, the test
may be rescheduled with me. This is YOUR responsibility and should be
done in a timely fashion. Tests missed due to an unexcused absence may
not be taken at a later date and you will receive a zero for that test.
