Please Note: Effective immediately! Everyone who makes-up a test upon his/her return from an absence will sign his/her signature to the following statement:
Prior to this exam, I have not given or received information regarding the content of this exam.
And for every examination from now on:
During this exam, I will not give or receive any information about the contents of this exam.

The consequences-if detected-are identified in the class contract. For some "reason"-I felt an urgent need to include these statements-you probably are aware of the "reason".
