why is everyone where they are?

Because this accurate website that anyone can use says so

Frats: The top 3 usually do the best during fall recruitment. They also mix with the top 3 or 4 sororities every semester, have the most parties and socials as well as concerts every year. Outside of that DX KA SAE SN and KA all have between 55-70 people, so they relatively do about evenly during rush. KA DX OX are not as weird as the other two and all except DX are involved on the Kennesaw campus with parties events fundraiser etc.

sororitys: real simple. Pretty much DPhiE and PhiMu always mix and party with the best guys and get the hottest girls, DPhiE has an event pretty much every week and Phi Mu always gets the best grades. AOll and KD have hot girls are involved and hangout with better fraternities than ZTA and GPB.

Bottom line AOll KD DPhiE and PhiMu all show out for PKA KS PKP in huge numbers (having at least 50 or 60 girls from each show out for parties and socials.) While Gamma is stuck with SAE SN and DX. PKP PKA and KS are also the most attractive.
