Since most LMS have the ability to contain more than one Adobe Captivate published project as modules within a course. I would recommend that you publish the course content as one module with bookmarking turned on, then publish the quiz as a second module with bookmarking turned off. This is the only way I can think of that would accomplish what you want.
"...the learner has to resume through the quiz which they inevitably will fail because now there sum will only include the quiz question of the active session, not any quiz questions from the previous session."
Are you sure about this? Maybe different LMSs handle this in different ways, but ours - Cornerstone - retains the points scored during the first session when dropping off in the middle of a quiz, and then adds them to the ones scored after having resumed.
I agree with Gaanf. My understanding of the way Resume Data bookmarking is supposed to work is as he states. The LMS retains enough data from the bookmarking to know which quiz questions have been answered so far in the session and what answers were given.
However, not all LMSs have good functionality in this area of bookmarking. So it is quite possible that the original poster's LMS is one of those that doesn't retain all the information, leading to the error he describes.
I would suggest he upload the same module to SCORM Cloud and test the bookmarking there in that LMS. Then if a difference in behaviour is noted, go back to the technical people in charge of your own LMS and start asking questions. It may be that they haven't configured the course (or the LMS) to support Resume Data Bookmarking correctly.
Absolutly certain. I will verify in SCORM cloud as well as Rod suggests when I get back from holidays.If it's working there I'll reach out to the LMS vendor (Skillsoft) and get back to this post with my results. Thanks
