Hello, I think your GPA is excellent and having all your prerequisites is a plus. The TEAS is not very difficult but I would definitely get the study guide and practice tests on the ATI website. Have you spoken with the nursing dept. advisor or attended an information session? I think they can answer your questions about the Chem or Biol class. Maybe you can get a waiver? Have you checked the MC Nursing dept website? There is a point system that the Nursing dept uses to accept students in the program which is on their website. Best wishes to you!
