requirements

Hi! I am really confused on what the houses look for during rush. I fall rushed with a 4.0, volunteer hours, played volleyball, had several rec letters, knew at least 1 girl in every house (if not more), have clean social media (no private accounts either) and was OOS but got dropped by 8 houses after first cuts. After reading through greek rank many people would consider the houses i had left "bottom houses". I am genuinely confused on what the requirements are for rushing.
