Exams:  A0  A1  A2   B0  B1  B2  

Answers:   A0  A1  A2   B0  B1  B2  

6 Tests = 3 versions x 2 variations: Each of the 2 variations (A, B, ...) represents a different random selection of questions taken from the study guide.The 3 versions (0,1,..) all have the same questions but in different order and with different numerical inputs. Unless all students take version "0" it is best to reserve it for the instructor because the questions are grouped according to the order in which they appear on the study guide.
