Multi Level Quiz

Greetings all,

I'm sure this question has been asked before, so if someone can guide me on this, I'd really appreciate it.

I am constructing a quiz in Storyline 3, (It could have been done in SL 1/2) and there are 3 student levels (difficulty) and a fourth difficulty level (easiest) common to all.

When the user commences the quiz, they are offered a choice of quiz pertaining to their training/skills level, they click on the button and their quiz commences, so here is my question...

Can I have one quiz bank, where all levels of questions are graded to the appropriate skill level, in other word a person at the lowest skill level will not be given questions from a higher skill level? Is this possible?

I have 3 different quiz banks and have added the set of common questions to each, it looks sloppy, in the sense that I have three different quiz banks and three different results slides. I would love to make this more compact with only one result slide. 

Has anyone any ideas that may help? Thanks all - Vincent
