I created a course in Captivate 2019 with non graded Knowledge Check Questions and a graded Quiz. I tried it in SCORM Cloud and it worked with no issues. The grade I received on the Quiz matched the report generated at the end. I then published it and uploaded the Zipped SCORM file to our LMS, Target Solutions (which supports SCORM 1.2). I went through the course, took the test and received my immediate score of 100% at the end. But when I received the generated report from Target Solutions it showed that I had received a score of 80% on the quiz. Does anyone have any ideas why there would be that discrepancy?
Since it works perfectly in SCORM Cloud, conclusion is that something is awry in that LMS, not with Captivate. You need to talk with the LMS people and tell about the checking in SCORM Cloud, the Standard for SCORM courses.
