Here is the link to OSU Greek life:

I found the 17 NPC groups (since you mentioned going through recruitment) to be very informative as far as links to local and national websites. I'm sure if you were to check into these, that you'd find a lot of information about each group that will help guide you (such as philanthropy, ideals, etc.)
Also, for Alpha Chi Omega, we make our 5 membership requirements open to the public. Feel free to visit our website and see how each of these pertain to you:

Good luck in your quest for possible greek membership. I know that you will find out VERY quickly that stereotypes are just that!
Feel free to PM me for more information!!
