Hello

I am a 25 year old single mom. My AS gpa currently is 3.40. I graduate in May 2012. I recieved 3 F's due to hardships and plan on retaking those classes in the summer. My advisor told me that it would boost up my gpa but I am unsure by how much and the influence it would have on grad school committees. I am planning on doing a double major for my bachelor's degree-- a BSN and biochemistry (I only have 6 more classes). I have not taken the GRE and do not have critical care experience yet. If I need to, I've heard suggestions to take higher level gradute classes and shadow. But am I on the right track or do I have a shot?
