sorority

Im literally in the same boat with the same questions :((

Most sororities here don't do informal rush except for a few lower tier

Informal rush usually 1 or 2 chapters do it. DG pretty much always does it. Are you in formal recruitment now? A few chapters have taken juniors before.
If you chose not to participate in recruitment and informal doesn't go your way, Maybe colonizing Pi Phi would be a good option to consider? They're looking for all grade levels to start their sorority.
But colonizing a sorority is way different from formal sorority recruitment. Your getting interviewed by adult alumnae usually as opposed to your peers (sometimes they bring in collegiate members from another school, but usually not until the end). They're looking for leaders to build a good foundation and grow a chapter here. You probably won't get a typical big/little week or some of the typical established sorority things , but If you think you can do that give it a shot!

If you have questions and are in recruitment right now, GO ASK YOUR RHO GAMMA. That's what they're there for.

I didn't do formal rush and I'm a sophomore right now so I was wondering what I should do next year
