Quiz in storyline

I am a new user, so if this has been answered before, I am terribly sorry.

I have a "Final Self-Test" that consists of 11 questions.  Our users will need to score 100% in order to pass the class.  My questions are:

1.  If they get one wrong, do I need to go into each slide and redirect it to where they learned it previously (which is what I did with 2 other quick quizzes earlier in the presentation)?

2.  Is there a way to then have them just re-answer the one(s) they get wrong instead of taking the whole test again?

Thank you!
