I need some advice on fraternity rush

hey,
I am a freshmen at Purdue(Second-Semester Freshmen) and I am rushing for fraternity. I just want to know how what to talk about with the brothers in the fraternity so that i have a good shot at getting a bid. Also, there are only 3 rush events left ( I started rushing a bit late.) I am asking this because I am very nervous about the rush event as I was not offered a bid in the last rush event and my friend was. Also, there are only three rush events left. And this is one of the last fraternities whose rush events are not over. I just want some advice on what type on conversation to have or how to stand out from other rushers.
