If you wish to take a test or the examination at its default date you need do nothing but attend class. If you do not take a test by its default offering you will be assigned a grade of zero for that test and may NOT repeat it.
Email is preferred.
State your name, student number, the test you wish to take, and the day you wish to take it. Be sure that you are ready when you schedule a test or exam. The exam may not be repeated. Each of the nine tests may be repeated once if originally taken by the default offering with a score of at least one point. All tests and examinations will be graded by human beings.
