How to create sections in same project

If I were doing this, I would just create my own quiz interactions using custom buttons and advanced actions. And this would control the ability to "pass" each section. 

Then, I would just do a final quiz at the end after completing all 3 sections that is actually caculated in Captivate and pushed out via SCORM. 

This allows you to "lock" each section behind a Knowledge check, and then have a clear representation of overall project knowledge by cumulative quiz at the end of the course. 

An alternative to that is using clearly distinct point values for the quizes for each section. Like, 10 points per question in Section 1, 11 Points per question in Section 2, and 13 points per question in Section 3. That way, each question is basically still worth the same in each section, but the total points will be unique enough to gauge which section they were missing the most questions out of. 

Hey There,

You can make a main slide and make interaction buttons for each section, when section ends and quiz completes last slides returns user to the main slide. This should be done, but I don't know how to handle 3 different quiz scores in Scorm. In Captivate 12, editing something is really limited.

So what I understand you are trying to do is have a single project with three sections. If a learner chooses a particulat section then only the slides for that section must be displayed. You then want a quiz to be completed based on each section. If this is what you want, why not just create three separate projects? 

Everything can be done except the quiz. I do not think a single project can have 3 separate quizzes in it.
