Calculators will be cleared before the tests begin. Any stored data on them may be lost. The exact format may vary from test to test. Don't expect any particular format. Just make sure that you understand the material, and that you have practice enough so that solving any typical problem becomes a routine.
Time is always scarce time during a test.
Attendance will be kept and will constitute part of your grade. In addition, if you are absent from class, it is your responsibility to cover the portion of material you missed and the assignment that was given. However, do not expect a private lecture because you couldn t make it to class. A make-up test may be given only with a valid reason for absence. The instructor will determine if a reason is valid.
