To see which Assignments are Assigned to you, click the My Dashboard link in the top navigation menu and make sure you're on the Assignments tab.
From here, you should be able to see all Assignments that your Admin has assigned to you, and you can see details like who assigned the Assignment to you, when the due date is, and your completion status (In Progress, Completed, Past Due, etc.).
You can click on an individual Assignment line item to expand it and see what content is included in the Assignment. You can click on the sub-items directly to go to the Courses or Policies listed in the Assignment, making it easy to complete Assigned materials without having to scour the Academy site to find them.
