The homepage of your account has two sections, What’s New? and Most Popular

What’s New? is a section that contains the Content Bundles, Learning Paths, Courses, and Resources that have been newly added in the system. You can buy the Catalog Items displayed here or enroll for the free courses available. This section also displays the free courses that you’ve been enrolled into directly. 

Most Popular section displays the Catalog Items based on their popularity among other users.
