advice for incoming transfer

From what I've heard rush at TCU is nothing to stress about, but me being a transfer student I'm worried. I will be a sophomore this year and I know they only recruit a few every year. Based off what I've heard, I've narrowed it down to three fraternities: Pi Kapp, Lambda, and SAE. If anyone can give me some info on what to do before rush and how to prepare for it or just any tips I would really appreciate it.
