So...that isn't 100% that is 100 points, which may not (depnding on the module) be a passing score. In Captivate, default score for a question is 10 points...if you have 20 questions, 100 would be 50%. Also, it depends on how you created the module. Is the module looking at a grade for passed/failed or is passed/failed determined by slide views? How you set up the module determines what Moodle does with it.
Other things that can impact are whether the student is using a computer or a mobile device (like a phone or a tablet) and whether they are using the mobile app if they use a mobile device. There are frequently issues with mobile devices reporting properly if not using the mobile app.
