bid day question

It's miniscule. You're really only at risk of going bidless if you have only 1 invite for pref. Girls who go to two houses and don't suicide always get a bid. Might not be to your first choice, but formal recruitment works in your favor and you won't go bidless. That's how RFM works. With that being said, it's still possible to get cut from everyone BEFORE pref. But if you make it to pref with 2 houses (and don't plan on suiciding) then congrats you're joining a sorority.

You'll hear a lot of girls saying they "didn't get a bid" but in reality they just didn't get a bid to the house they wanted so they dropped. But they don't like to say that because then no one feels sorry for them.
