Multiple Choice Knowledge Check (Ungraded - Multiple Attempts Allowed) Restricted Menu

Hi, I am new to Storyline 360 (and eLearning development in general). I must include 10 multiple choice-type knowledge check questions throughout the course I am developing. The learner may attempt as many times as needed but must answer correctly before being allowed to move ahead (course is set up as restricted menu and navigation). A results slide is not needed as a "gradr" is not required - they simply have to slect the correct answer before moving ahead in the course. Once the correct answer is submitted, the learner should not have to answer again upon a revisit - so the slide is set to "Resume Saved State" upon revisit.

Could someone please review the knowledge check I created (attached) and let me know:

• if there is a better way to do it? Or,
• if you see any potential problems with restricted navigation, or the next button, that I may encounter down the road?

The "A" and "B" slides are there simply to illustate behaviors of the Prev and Next buttons.

I have practiced various anticipated learner behaviors depending on how and when the learner moves back and forth between slides and so far I can't see any issue. However, I feel there may be a better way to accimplish this, or perhaps I should be using some kinds of triggers/variables/conditions to make sure what I expect to happen does. I got burned earlier on an interactive slide I created with layers and had to add variables and conditions to keep the learner from getting stuck or bypassing content. I just need to make sure this knowledge check is okay, since it has layers as well, without adding anything more.

Thanks so much!
