Hidden results not working as intended

Hi, we're using 360. We made a quiz with 10 questions. It's disguised as a survey. We are trying to determine if something that's occuring is training related or is a perfromance issue. We have people take the "survey" answering 10 questions.  At the end we just thank them for completing it. We don't show a pass or fail. There is a results slide where the results are submitted. To make sure this is a one and done item, the passing score is set to zero. This way the LMS  (Saba) will sign it off as completed. This works but we discovered a flaw. If a person does not complete all the questions, they still get marked as completed in the LMS due to the zero score requirement. I'm trying to figure out a way where they have to complete all the questions. If I use track by slides viewed will I still get a score reported to the LMS? I'm also wondering if this happens with other percentages? Like if I had 10 questions and I set the passing score to 80%, if I only answered and got the first 8 correct and then exited, would it report 80% to the LMS?
