Explanation
Advising Pools is a feature that allows students to schedule appointments with any available advisor directly from a portal. Advising Pools enables advisors to set their availability and preferences, and students to see which advisors match their needs and book appointments accordingly. Email to Case, Success Teams, and Early Alerts are not features that allow students to schedule appointments with advisors from a portal.
