As I understand it, if you have set "Reset on Revisit" to false in the Assessment configuration and 'Store Responses' set to true in the spoor configuration then the code should save and restore the user's responses to assessment questions if the user:

• quits the assessment without having answered all the questions
• completes and passes the assessment
• completes it and fails but has no more attempts remaining

One thing that could stop it from working is if you have a LOT of questions in your course. SCORM 1.2 is quite limiting in the amount of data that can be stored - just 4KB per SCO. You could exceed that if you have a lot of questions, particularly when creating content using the authoring tool which generates fairly lengthy (24 byte) component ids.
