Multiple scoring Scenarios (cross posted to Storyline forum)

Hi everyone,

I'm developing a course and taking a first step towards gamification.  I have a series of interactions that when a user finishes looking at allows them to choose to complete an embedded interactions. If they get everything correct they will receive one score, if they get it wrong they receive a different lower score. I want users to receive a third potential score for having at least viewed only the relevant information without having gone through the interactions. My problem is that I only want this to be scored once. Right now each time they view that set of slides the score continues to build. How can I get Storyline to add to my final score only once. I've attached my Storyline file for anyone to take a look at. Thanks in advance for any help.
