Prevent a question from be randomly selected twice from a question

Hi Ashley,

My apologies if I’m being unclear!  I think I over-simplified my problem too much in my previous post. I’m re-opening this thread since there may be a problem with Pat’s proposed solution (although I may be misreading Pat’s proposed solution too!) …but the problem is this: I have an Exam for students. The Exam consists of 3 quiz questions that are randomly pulled from a bank of 12 possible questions (“A” to “L”).  

Here are the rules for the Exam:  

Rule 1 - The student is allowed to take the exam twice (at most).

Rule 2: the student is never allowed to be presented with a question s/he has seen on their first attempt.

Let’s say that on the first try, the student is presented with Questions “A” “I” & “L” (selected at random by Storyline). Let’s then suppose that the user fails. He/She is then allowed to re-take the Exam one last time.

Let’s then say that on the second attempt, the user is presented with “A”, “E” and “L”. The solution for “A”? Have Storyline re-direct a student to the next question ( “B” ) automatically. This works well for all questions …except for “L” (the last quiz page in the question bank). On the student’s second attempt, I can’t re-direct the student from “L” to the next question (since it doesn’t exist). How should I handle quiz "L"? Am I missing something when I read Pat’s solution?
