Learner Home and adding courses

I am trying to add a course to My Courses for a student.  I see "Get Ready for xxx math" for grades and high school topics but not pre-algebra.  So, is "Get Ready for 8th Grade Math" a course for students entering 8th grade and/or students entering pre-algebra?  Or is "Get Ready for Algebra 1" for pre-algebra and Algebra 1?

How does a student add "Eureka Math/Engage NY" or "Illustrative Mathematics" to My Courses?  I see these math courses when I use the main search tool for courses but when I try to add to Learner Home it does not show up on the list even when I click on See All.

Thank You,

Linda C. McKinney
