Is there a way to prevent users from taking a test in Cp CS6 without first visiting all content slides?

[JoinerB]

For example: Can a course only be considered "complete" in an LMS once the user has visited all slides AND successfully passed the final test?

[RodWard]

Yes. You can set this in the Quiz > Reporting settings.

The Subject of your question is different from its content? Rod answered to the content, you can indeed set up the requirement to have both pass on the Quiz and % of slides visited. That will not solve the issue in your subject: prevent the user from taking a test in Captivate 6 (was never part of a Creative Suite, CS) before finishing the content slides. What did you really want to know, please?
