What gpa is considered too low?

please help!! what GPA is considered too low, I know they have a limit to which you can rush I mean even if my GPA as an incoming freshman from high school school is within the requirements to rush

Like which GPA do they see and think it's too low and drop them from round one?

i'm pace so i'm very nervous, im not picky ab sorority's i just want to join one!! I always tried hard in school, but academics has been difficult for me, I'm hoping they can look beyond my résumé and see my character.
thank you!
