Sophomore Quota

[PNM128]

Forgive me if this has been asked before but I've tried searching through the threads on here to have this answered. My school has a sophomore quota (and since I'm rushing as a sophomore, i thought this would be beneficial), however, I've read a lot on here that sophomore quotas aren't the same as regular quotas. Or something along that lines, meaning, that the sororities don't really need to fill it. My school's recruitment page states this about sophomore quotas: "An upperclassmen quota is a seperate quota that is used to specifically place upperclassmen Potential New Members. It makes the recruiment process more friendly!" So I thought it was like an extra added onto the regular quota. Like if the sororities had a quota of 60 and then they would have a sophomore quota of 10 or something that they would also fill. Is this right or do I have it wrong? Aren't sororities' goals to fill their quotas?
