How does General Admission seating work?

Family member wants to buy general admission tickets to Louisville game but wants to know if there are different types of general admission seating? For example, different levels?
Also, do you sit where the ticket printout assigns you for general admission, or is it open seating in the general admission area (ie: first come, first serve)?

open seating in either GA area, but the west endzone is the “family zone”. the east EZ is right over the student section and is student overflow

Thank you!
