I also remember there being 10-12 girls per group. One girl from my group was cut after the first round of open house. A few others dropped out of recruitment after pref. Only 6 from my group accepted bids.
Again, this is just my personal experience from over 5 years ago!

I'll be around Sunday, Monday, & Tuesday helping out with recruitment & Thursday for bid-matching.
Good luck & HAVE FUN!
