Apex says activity is denied and is proctored. What does this mean?

It is a test and must be taken in class. CUSD requires that tests are taken in person. Be sure to plan ahead so that you are able to take your exams before the due date arrives.  Items are always due by midnight on the assigned date.  Once the due date has passed, a score of zero is automatically entered.  Zeros are recorded at 12:01 am.
