There are only 16 chapters that participate in formal recruitment, there are 26 time slots so the parties aren't so crowded. PNMs will have breaks in their days.
Thank you, dear ... I've been having some health issues for the past two years and thought I had missed a significant change.
How many first round parties do the chapters have to hold?
You would probably have 5-7 groups per part if you have 20 in a group but my guess is they have more than 20 per group. Don't really know how Bama does it, but the universities I work with have more than that in each recruitment group.
