Since I used to go to UF I can say this.....
ZTA, KD and ADPi are very selective....you should feel really good about being invited back to those houses....I mean very good....also they are among the strongest chapters on campus. Rush gets better as you go along at UF the first two days are the worst. GOOD LUCK!!! And a word to the wise for UF dress up a little more than they tell you...if they are telling you to wear shorts, sneakers, and tshirts for first and second dont listen to them....wear capri pants, a skirt or a sundress instead
