Interest in Higher Education

I received a BSN over a year ago and have begun inquiring about MSN admission requirements. I graduated from my BSN program with a 2.7 G.P.A. Unfortunately, I am finding out that most schools want a person to have at least a 3.0 for admission. Can anyone offer ideas on how I might be able to get accepted with my low G.P.A or should I go back and retake Nursing classes to raise it? Any ideas will be greatly appreciated. Darlene
