Most Efficient Way to Import and Implement 'Practice Quizzes'?

I was recently brought in as part of a company's Continuing Education department, and am currently working with them to migrate all of their courses (about 134 total) from the Moodle platform to a different Learning Management System. Unfortunately, the current courses were all built into Moodle in a piecemeal fashion as opposed to being in SCORM packages, as the new LMS requires.

I've been evaluating different authoring tools, and will likely end up using Captivate primarily for its ability to easily import Moodle's GIFT-format quiz questions. As you might imagine, this should be exceptionally more efficient than manually rebuilding each course's quiz questions.

I've been able to successfully export course questions from Moodle and import them into Captivate, which is fantastic, but there's one other wrinkle that I need to deal with. The licensing and certification board that oversees our field requires that, in addition to each course having a final graded quiz, each course also needs an ungraded 'practice quiz'.

I've explored Captivate's 'Knowledge Check' question type. That seems like it would be a great fit for our practice quizzes, except that Captivate imports questions for the 'standard' quiz by default and apparently lacks the ability to easily convert those slides into Knowledge Check slides. Another forum post definitively indicated that Captivate 9 had no ability to convert Knowledge Check and standard question slides; I'm assuming this is still the case in Captivate 2017?

If so, then I'm trying to figure out how to most quickly and easily set up the needed practice quizzes. The practice quiz questions are included along with the final quiz questions when exporting from Moodle, so it'd be ideal if I could just bring in everything at once and then modify the practice questions as needed. Keeping in mind that those practice questions do not need to factor into the user's final quiz 'score', would it be possible to build a second quiz into a course that has its own overall feedback screen, but is discrete from the final quiz questions, without using Knowledge Check slides? Would the Question Pool options be useful for this?

This is my first experience with Captivate, so I apologize if I'm missing something simple. I've tried to do my due diligence in searching through the help documents and forums, but I feel like someone who's more knowledgeable might be able to more quickly get me to the best approach for this need.

Thanks in advance!
