help!

I graduated in 2012, went to a Christian school that fall, took a year off, and transferred to the U of A fall 2014 as a transfer freshman (11 hours didn't transfer from the private school). I really want to rush this fall, but I'm 21. Would that make make a difference to some sororities? I am in 4 honor societies, have a 3.8 GPA, and tons of volunteer work.
