how to get zeta

ik i shouldn’t went a certain sorority going into rush and i don’t want to be bias but im rushing as a sophmore and since ive been at txst for a year i kinda know what i want in a sorority already and ik zeta well enough to want it more than the others but i dont know lots of girls to get in like that. soooo what do i have to do either during rush to get zta or socially?
