I go to a top tier public university and have a 3.98 cGPA and a 38Q MCAT. I have done research in a biochemistry lab for two years and also did research at Rush Medical School over last summer. Besides that I was the service chair for my pre-medical fraternity, volunteer in a local hospital (three years), and I am an EMT-B. I was wondering what my chances are for some of the top tier schools such as U of Chicago, Northwestern, U of Michigan, Columbia, etc. I know my scores are competitive but what are my chances coming from a state school?
