Possible Scenario:

1.  My exam term does not have all the classes, do I copy the term classes from here?


Do not copy the term classes from the Exam Terms.  The exam term may only include academic classes and disregard classes such as attendance, term comments, and etc. You will want to copy the classes from the most recent normal term. 

In the example below, you would copy from Quarter 2 to Quarter 3.
