Girlwholived,
I wouldn't worry too much. I received my acceptance to UIC in mid March to the advanced standing program, however I know other people that are still waiting. I do think that concentrations are a factor in the process. I was also accepted to the mental health concentration and it is my understanding that less people apply to this concentration. I know someone currently attending Jane Addams that did not receive their acceptance until May last year. Also, I have declined the offer from UIC for another program. Hopefully that will free a spot for someone. Good luck! Don't worry too much, your stats sound really good! I'm sure it's just a matter of time.
