Saving progress in Rise360 course

Hi there, I am having trouble searching for information that helps me understand the set up in my Rise360 course that enables the progress to be saved as you go in a Rise360 course.

I have there are 6 sections totaling 15 lessons in the course with a knowledge assessment or quiz after each section.  I want the learner to be able to start and come back to that spot later if needed and not have to restart.  

Thanks

Tanya
