why did adpi get 87 new members

Because more than half will drop

There are two numbers that determine how many new members a chapter can take: quota and total. Quota is basically determined by taking all the PNM's attending preference parties and dividing it by the number of chapters on the campus. Each house can take up to that many girls as new members.

However, under RFM (the system most colleges use to place girls in sororities) every girl who attends all the preference parties she is invited to (doesn't suicide, doesn't drop out before preference) should get a bid somewhere, so if every chapter she goes to for preference filled their quota before they got to her name, she would be added to one of the houses she preffed as a quota addition, and that house might be a little over quota in that case.

Total is the total number of members any chapter on campus is allowed to have. This is determined by panhellenic. If a chapter is going to have fewer members than the total even after they add the quota amount, they are allowed to give bids to more girls than that amount (bid up to total), so they may have a larger pledge class. Hope that answers your question.

They got so many because ADPi is the bottom house and under RFM they keep inviting almost everyone. They have the most girls coming back to preference. So, everyone else takes their new members and then all left overs that attended ADPi at preference get bids there.

Have you ever thought that maybe a lot of the girls ADPI got actually preffed them first and actually want to be there? Be happy that they got the girls that they did because I'm sure that took a lot of hard work and dedication on their part. You all are making it seem like someone would rather be a GDI than be an ADPI, but based off the looks of their new PC this isn't the case 🤗
