Mark course Complete in LMS by passing Quiz, not actually taking the course

Client has a course that includes Books, Book Pages, Simulations and a Quiz. The client wants to mark the course as Complete in their LMS if the user passes the Quiz - even if they skip all the course content.

What would be the best way to do this?

* All the Books have been set to not track completion (uncheck Track Completion of Book)

* The only KB I found was this one

* LMS is not SFSF LMS

* SCORM is 2004 4th Edition
