Is it ok not be in a sorority at State

Is not being in a sorority ok at Mississippi State? Or will a girl’s college experience be doomed if she in not part of Greek life at State? And if a girl goes through rush week at State - should she be honored to be invited to join any sorority at State? Are all the sororities equal in popularity or are there any that are considered lower tier and a girl shouldn’t join if it’s considered lower tier?
